PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.
Should I use PEX A or B?
Bottom line, PEX A is more resistant to burst pressure than PEX B. PEX A’s expansive material can handle up to 500 PSI, which makes it reliable in extremely cold temperatures. Since PEX B is a more rigid material, it will not hold up as well in similar situations.
What’s the difference in PEX A and PEX B?
Again, the main distinction lies in the manufacturing method, which is what assigns an A, B or C to PEX. PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there.
Should I use PEX AB or C?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
Is PEX expansion or crimp better?
PEX crimp equipment is a lot more affordable than the expansion kits. However, despite the pricing and form shortcomings, most plumbers prefer to work with expansion because installation is more efficient. There are fewer leaks, and it also seems to be more durable against extreme colds and frozen pipes, etc.
What is the difference between PEX and ProPEX?
The letters PEX stand for cross-linked polyethylene, and this acronym usually refers to a type of water pipe that’s revolutionizing the plumbing and heating industries. PEX pipe is made by a handful of companies, but the best version I’ve discovered so far is part of a system called ProPEX.
Which is better PEX crimp or clamp?
If you are looking for a fast and more secure connection that will stand the test of time, crimp tools are your better option. But if you want more flexibility without working more, go for PEX clamps.
Is SharkBite PEX type A or B?
SharkBite non oxygen barrier pipe is manufacture as PEX-B and SharkBite oxygen barrier pipe is manufactured as PEX-C.
Is Apollo PEX A or B?
Apollo offers PEX-A (Expansion PEX) and PEX-B tubing. PEX-A tubing (Expansion PEX) is produced using the Peroxide or Engel method. PEX-B tubing is produced using the Silane or moisture-cured method.
Is Zurn PEX A or B?
Zurn Pex, Inc. chooses the Silane (PEX-b) method to manufacture its tubing. While high degrees of cross-linking can be achieved using this method, it is unnecessary because the density of the base resin for Zurn PEX is higher compared to PEX-a and PEX-c methods.
What happens if you expand PEX B?
Lab tests have shown that while you can create an expansion connection with PEX-b, it will not hold as securely as a PEX-a connection. The stiffer quality of PEX-b pipe can create tiny cracks in the pipe wall when expanded, compromising the fitting connection.
Can you use blue PEX for hot water?
Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold. These colors are just for your convenience. Plumbing code does not require the pipe color to match the type of water supply.
What is better crimp or cinch?
Asides for its versatility, the cinch tool is also cheaper than the crimp tool. The cinch rings can be slightly more expensive than crimp rings. A cinch connection will last over 5 years and can last more than 10 years. Crimp connections consist or a crimp ring, a crimp tool, proper fittings and a go/no-go gauge.
How long does PEX pipe last?
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
Is there a recall on PEX plumbing?
$43.5 Million NIBCO PEX Class Action Settlement Announced On October 26th, 2018, the NIBCO PEX Settlement Administrator and Plaintiffs’ law firms announced a class action settlement involving allegedly defective PEX tubing, fittings and clamps. Polybutylene piping replaced under the class action settlement in 1995.
Is Viega PureFlow PEX-A or B?

Is Uponor and Wirsbo the same?
Uponor (formerly Wirsbo) has been making PEX pipe for radiant floor heating since 1970, longer than any other PEX manufacturer.
What type of PEX is Viega PureFlow?
The Viega PEX system uses the PEX-b tubing (although you could also use another brands PEX-a) and a pressed ring securing the PEX to the fittings. Some advantages with the pressing system is that the fitting are now available with press rings already built-in.
