The most common crimp for PEX is a copper sleeve with an integral stainless steel stiffening clip, which is sometimes referred to as a “cinch” or “crimp-style” fitting. It is most widely used for connecting rigid piping to PEX.
This fitting is frequently used for PEX water supply lines, as it is easy to install and highly reliable. There are a variety of different cinch style fittings available; one of the most widely used is the Cinch-Seal® from Oetiker Group.
This fitting is designed to provide a secure connection and seal against leakage. It comes in various sizes and can be used in a wide range of applications. Additionally, other types of crimps, such as SeaTech’s crimp-style clamps, are best suited for use with flexible tubing, such as PEX-AL-PEX.
This type of fitting does not require the use of an integral stiffening clip and provides a quick and easy installation process.
Are all PEX crimp fittings the same?
No, not all PEX crimp fittings are the same. PEX crimp fittings come in a variety of different materials and sizes, allowing you to choose the right type of fitting for your project. For example, some PEX crimp fittings are made of brass, while others are made of stainless steel or polyurethane.
Additionally, the size of PEX crimp fittings can range from ¼” up to 2”, depending on the job being performed. Therefore, PEX crimp fittings can vary considerably, making it important to make sure you select the right fitting for the job.
What is the difference between PEX crimp and PEX Clamp?
PEX Crimp and PEX Clamp are two different methods of connecting PEX (cross-linked polyethylene) tubing with fittings. The primary difference between the two systems is the type of tool required and the amount of force needed to make secure connections.
PEX Crimp is the most common type of connection, and it requires a PEX crimp tool to make secure connections. This system uses a copper crimp ring with a reusable PEX crimp fitting to make a connection.
The crimp ring is inserted into the PEX fittings, and the PEX crimp tool is used to apply pressure on the crimp ring, which compresses the ring and securely connects the fittings. PEX Clamp is the second type of connection and is commonly referred to as the “cinch” style system.
This system requires a PEX Clamp Tool and a PEX Clamp to make secure connections. The PEX Clamp is inserted into the PEX fitting, and the PEX Clamp Tool is used to apply pressure on the PEX Clamp, which compresses the clamp and securely connects the fittings.
PEX Clamp is the preferred method for hot and cold water applications due to the secure fit of the connection, and the amount of force required to make a secure connection is much less than with PEX Crimp.
Overall, both the PEX Crimp and PEX Clamp methods of connection are reliable, however the choice of which system to use should be based on the application and the specific requirements of the project.
Which is better PEX crimp or pinch?
It depends on the situation and the preference of the user. PEX crimp fittings are more secure and less prone to failure than pinch clamp (or crimp) fittings. This is because the PEX crimp fittings employ rings that are placed around the tubing and crimped with special crimping tools to create a tighter seal than can be achieved with pinch clamps.
PEX crimp fittings also provide a cleaner look, since no hardware is visible after being installed.
Pinch clamps (or crimp) fittings are a bit easier to use since there are no special tools needed and the installation process is fairly simple. However, due to the lack of compression, pinch clamps may have a higher failure rate over time.
Also, pinch clamps are more likely to leak due to movement and vibration.
In conclusion, it really depends on the usage and preference of the user. PEX crimp fittings are generally more secure and less prone to failure, while pinch clamps are a bit simpler to use, but may not always be as reliable.
Can you crimp PEX twice?
Yes, you can crimp PEX twice, as it requires two crimps in order to secure the tubing to the fitting. The first crimp should be done on the tubing with a cinch clamp tool, and the next crimp should be done near the fitting with a crimp ring tool.
It’s important the tubing is cut cleanly and the crimp ring is properly centered on the fitting barb before crimping. Even with two crimps, PEX tubing should be tested for leaks before putting a structure back together.
Can PEX A be used with PEX B fittings?
The answer to this question depends on the type of PEX A and PEX B fittings you’re talking about. While most PEX A and B varieties are interchangeable, there may be exceptions depending on the particular product.
Generally, if the fittings are both made for the same PEX type (e. g. both for PEX A or both for PEX B) then they can be used together. However, if different PEX varieties are being used (e. g. a PEX A fitting and a PEX B fitting) then they may not be compatible, or they may require a special transition fitting to make them work together.
It’s always best to consult with a professional to make sure the fittings are compatible before attempting to install them.
Is there a difference in blue and red PEX?
Yes, there is a difference between red and blue PEX pipes. The difference between these two types of PEX pipes is mainly due to the way in which they are manufactured. Blue PEX is manufactured using a cross-linked polyethylene (PE-X) process, which results in a higher degree of elasticity, flexibility and strength.
Red PEX is made using a different process called acrylonitrile butadiene styrene (ABS) and it is less flexible and slightly less durable than blue PEX. Both have similar heat and pressure resistance, but the difference in elasticity and flexibility is the main reason they are used in different applications.
Blue PEX is commonly used for plumbing and hot and cold water pipes, while red PEX is more often used for hydronic heating applications.
Are plastic or brass PEX fittings better?
When it comes to deciding between plastic or brass PEX fittings, there is no single right answer. Both have their own benefits and drawbacks and ultimately the choice is up to the individual based on their own needs and preferences.
Plastic PEX fittings are usually less expensive than brass fittings, making them a more cost-friendly choice. Additionally, plastic fittings are easier to install and provide a secure connection. However, plastic fittings are not as durable as brass, so they may not last as long in certain harsh environments.
Additionally, brass fittings tend to be more aesthetically pleasing and may be better for certain décor applications.
Brass PEX fittings tend to be more durable and may be better for applications such as exposed piping in garage or outside. Brass fittings are also preferable for applications that may require high pressure such as water lines.
However, brass fittings can be more expensive than plastic and may require additional tools for installation.
In the end, the decision between plastic or brass PEX fittings is up to the individual and based on their own budgetary and aesthetic needs.
Are all brands of PEX the same?
No, not all brands of PEX are the same. Different brands of PEX can have different flexibility, chemical resistance, temperature range, water flow, and other properties. In addition, different brands may be priced differently, so it’s important to do some research to find the best value for your money.
Additionally, some brands may be more widely available than others in your area. Researching available brands and comparing the features of each can help you determine the best fit for your project.
Which PEX connection method is best?
The best PEX connection method depends on the type of project. Crimp rings are the most common and economic connection method, and they are easy to install. They can be used in both hot and cold water applications, but they are not recommended for potable water systems.
Cinch rings are the next most common connection option and they are easy to install. They require no additional tools, and they are recommended for potable water systems. In addition, they are slightly more secure than crimp rings, which make them a good choice for in-floor heating systems.
Clamp rings are a more secure connection type but they require special tools and they can be more costly. They are usually used in high-demand water systems such as hot tubs and outdoor sprinkler systems.
Finally, expansion rings are the most secure PEX connection methods, but they cannot be used on any type of system. They require more time and skill to install, but they are the best option for systems with high water pressures.
Do PEX crimp fittings restrict flow?
PEX crimp fittings do not usually restrict flow, though they can depending on the specific fitting used. Most PEX crimp fittings use a series of ridges on the inside of the fitting that helps focus the water flow and maintain a certain pressure in the pipe.
In some cases, if the wrong type of fitting is used, then the pressure being exerted can create a partial blockage, which can in turn reduce the amount of water that flows through the pipe. Generally, as long as the fitting is installed properly, it should be able to maintain a good flow rate.
In addition, most PEX crimp fittings are designed to provide an airtight seal, which can also contribute to a better water flow rate.
Can you use crimp fittings on expansion PEX?
Yes, you can use crimp fittings on expansion PEX. Expansion PEX is a type of polyethylene pipe that is designed to expand lengthwise as it is heated, which allows for greater flexibility when connecting fittings.
Crimp fittings are also well-suited for use with expansion PEX because they are easy to install and provide a secure, reliable connection. To connect expansion PEX to a crimp fitting, you will need a special tool designed to crimp the fitting onto the pipe.
This tool compresses the fitting onto the pipe and should be used according to the manufacturer’s instructions. The crimp fitting must also be manufactured specifically for use with expansion PEX. With the right tools and materials, crimp fittings are a great choice for connecting with expansion PEX.
Is PEX-A or B better?
When it comes to deciding between PEX-A and PEX-B, it is important to consider the type of project you are working on. PEX-A, or Cross-Linked Polyethylene, is a thermoplastic that is produced through a process called “engel”.
This process bonds the molecules together in a stronger and more durable way. This type of PEX is the most popular and is often used in plumbing projects since it is approved for potable water applications.
It is also more flexible and has less chance of breaking in freezing temperatures.
PEX-B, also known as Non-Cross Linked Polyethylene, is also thermoplastic created using a different production process. While it is not as flexible, it is stronger and more resistant to chemicals or abrasives.
It can be used in industrial grade applications or projects exposed to extreme temperatures (hot cycles), but not in those that involve potable water.
Ultimately, the best option for your project will depend on the application. If you need the flexibility of PEX-A and the assurance that it is approved for potable water projects, then it is the better option.
If, however, you need something more resistant to chemicals and abrasives, then PEX-B may be the better choice.
Do you need a special tool for PEX clamps?
Yes, you do need a special tool for PEX clamps. These tools are fairly inexpensive and are an important part of the PEX installation process. There are two types of tools available: a standard crimp tool and a clamping tool.
The crimp tool is used to make crimp rings, which are then fitted around the end of the PEX pipe before the clamp is placed over it. The clamping tool has blades which score the clamp and then press it down for a secure fit.
Using the wrong tool or not crimping the rings correctly can result in water leakage or improper sealing. For these reasons, it is important to use the right tool and to follow the manufacturer instructions when installing PEX clamps.
What can I use to crimp PEX?
The most common and recommended way to crimp PEX is to use a cinch tool or cinch clamp. This tool is designed to work with PEX clamps and rings. To use, simply insert a PEX clamp or ring over the PEX pipe and press the tool over the clamp.
The jaws of the tool will then compress the clamp or ring, securing the pipe in place. This method provides a secure watertight connection that is easy to install and maintain. Additionally, there are crimping tools specific to the type of PEX you are using, which provide a more precise crimp and are designed to fit specific sizes of clamps.
While these tools are more expensive than cinch tools, they are ideal for the more complex PEX connections. No matter which type of crimping tool you choose, they all offer a fast, safe, and foolproof way to connect PEX tubing.
Is it better to crimp or clamp PEX?
The answer to this question ultimately depends on the situation and the needs of the homeowner. Generally speaking, crimping PEX is the most popular and effective way to join the pipes because it provides a permanent connection when done correctly.
Crimp rings provide a reliable, watertight seal, with no need for additional sealants or tapes. Additionally, since crimping does not require glue, it does not require extra drying time, so the connection can be used right away.
However, for certain applications, or for those who do not have the necessary tools for crimping, clamps can also be used to form a connection. These clamps are typically made of stainless steel, making them a reliable option.
With clamps, there is no need for glue or sealants which makes the connection process much faster. The main downside of clamps is that they are not as strong as a crimped connection, and can be more prone to developing leaks over time.
In the end, it comes down to the situation and personal preference of the homeowner. For tight spaces, ease of installation, and faster connection times, clamps may be the best option – whereas for a more permanent and secure connection, crimping is usually the way to go.
How do you crimp PEX fittings without a tool?
You can crimp PEX fittings without a tool, however it is not recommended. A PEX crimp tool is specifically designed for the purpose of creating a secure and watertight connection. When using the crimp tool correctly, it will ensure the PEX rings are the correct size for a secure connection.
Without the crimp tool, it is very difficult to create a watertight connection, as the PEX rings will have to be crimped with a needlenose tongue and groove pliers, adjustable pliers, or vise grips. The pliers and vise grips lack the proper amount of pressure or a uniform crimping shape, making it difficult to get the right amount of compression needed to create a secure connection.
If the connection is not secure, leaks can occur, leading to water damage and higher water bills. It is not recommended to attempt to crimp PEX fittings without a tool, as it can be unsafe, inefficient, and lead to costly repairs.
