Looking at the marking is one of the easiest ways to identify PEX pipes since most manufacturers label them for this purpose. Usually, there are markings/printing on the exterior of PEX tubing that clearly says “PEX A” or “PEX B,” indicating the type of PEX tubing you have.
Can any PEX fittings be used with PEX-A or PEX-B pipe? Apollo PEX-A (Expansion PEX) pipe can be used with Apollo PEX-A or Apollo PEX-B fittings, brass and poly alloy.
Pex-A is slightly more flexible than pex-b. Pex-A fittings are not flow restrictive. If you compare fittings side by side, you'll see the inside diameter of the pex-b is much smaller.
SharkBite non oxygen barrier pipe is manufacture as PEX-B and SharkBite oxygen barrier pipe is manufactured as PEX-C.
SharkBite push-to-connect fittings listed to ASSE 1061 approved for PEX-A, PEX-B and PEX-C pipe. Note: Install SharkBite fittings at least 1 inch apart to enable disassembly of the joint.
Most plumbers say SharkBite fittings aren't strong enough to produce durable, reliable, long-lasting connections. Despite the absence of evidence, they continue to rely on soldering for their long-term plumbing projects. Thus, finding a firm that uses push-to-fit fittings can be difficult.
Apollo PEX-B tubing is cross-linked, high density polyethylene and is available for potable water distribution systems in red, white and blue colors for easy identification of hot, cold and main water lines.
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.
Yes, crimping is the best connection method when working with PEX B tubing and fittings.
Pinch Clamp Tools Work Better in Tight Spaces
Especially when your PEX is pressed up against a wall—or there is just otherwise very little wiggle room to work—crimp tools can become a much bigger hassle. The larger jaw of the tool means you need ample room behind your PEX to be able to make a proper connection.
Never try to expand the end of a PEX B pipe, as it is inflexible. The fittings are smaller as well, so pipe diameter is tighter at the joint. This increases resistance to flow, meaning the volume of water reaching fixtures is decreased.
The general answer is YES: PEX B fittings can be used with PEX A pipes, especially in residential applications, which offer flexibility in installation options.
In the case you're looking for a quick answer, the key differences between PEX-a and PEX-b piping are: PEX-a is approximately 64% more expensive.
The wall thickness of PEX A systems is normally greater than PEX B because it has a lower burst strength and hence requires the greater thickness to cope with the same operating pressures. Yes PEX A is more flexible than PEX B but both types of PEX have the same minimum bending radius.
PEX pipe can be used as a service line based on its corrosion resistance to soil and water, its long life and its oxidative resistance. Our PEX pipe is not suitable for use in areas where the soil is or may become contaminated, including soil used for backfilling.
The lifespan of PEX pipes is one of their most appealing features. On average, PEX pipes can last anywhere from 40 to 50 years, and in some cases, even longer.
Is Poly-B the same as PEX? No, they are actually very different types of piping. To discuss, poly-b is a type of plastic piping made from polybutylene, while PEX (cross-linked polyethylene) is a newer and more durable option that has been gaining in popularity over the past few years.
Expansion PEX tubing is cross-linked, high-density polyethylene. It's available in white, red, or blue colors for easy identification of hot and cold water lines.
“Soldering pipes is a skill, any allowing anyone to use plastic push fit fittings devalues the trade.” - There is still skill in fitting push fit systems - the MOST important skill a professional plumber can have is their knowledge and ability to recommend the best system for each individual application, and if this ...
Anyone who had problems with their SharkBite “Push-to-Connect” water heater hoses. What's Going On? Class action lawsuits have been filed alleging that the rubber inside the hoses can deteriorate and cause a host of problems, including the appearance of black flakes in the hot water supply and low water pressure.
How long can a SharkBite fitting last? SharkBite fittings and PEX pipe carry a 25-year warranty against any manufacturer's defect as long as the item has been installed in accordance with the installation instructions and complies with local code.
