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.
Which type of PEX connection is best?
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.
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.
How long do PEX clamps last?
ASTM International, a standards organization, requires that the life expectancy for PEX pipe be at least 50 years. (Some PEX manufacturers offer a pipe life expectancy of more than 100 years.) In short, PEX is more durable and provides longer system longevity with less time and material invested in the installation.
Is PEX crimping reliable?
Each method requires a different tool and a different type of ring, but the styles are similar enough that PEX newcomers frequently wonder which method is preferable. Crimping and clamping create equally reliable seals that will not leak when performed properly.
Can PEX A be clamped?
Using stainless steel pinch clamps, also referred to as ear clamps, are a great way to connect PEX pipe to PEX fittings. Connections made using SS Pinch Clamps with an interlocking design provide the same high integrity connection as a copper crimp ring connection.
Do you need a PEX crimping tool?
Connections for most PEX supply jobs require a special tool. There are several PEX supply connection methods, but only two affordable enough to be practical for DIYers: crimp rings and cinch clamps. Crimp rings are a band of metal, usually copper, that you slip over the fitting and compress with a crimp ring tool.
Do PEX crimp fittings restrict flow?
At a rate of 8 feet per second, the CPVC fitting will cause less than 1% restriction in flow while PEX fittings create a 23% to 54% reduction in flow, depending on the fitting used.
Can I crimp PEX A?
Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX. Crimp fittings are preferred for many applications since they are widely available and are the most affordable.
Is PEX OK for drinking water?
There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.
Where should you not use PEX?
PEX can’t be installed in high heat areas.
You can’t install PEX in high heat areas like near recessed lighting. This also means you can’t connect PEX directly to a hot water heater, but you can use a connecting material to do this.
Which PEX is crimp?
PEX B uses an insert-style fitting. After inserting the fitting into the pipe, you fasten it in place with a copper sleeve, using the crimp tool. Pro: Because PEX B doesn’t require an expansion tool, the joining method is faster and simpler than the process for PEX A.
Why do my PEX fittings leak?
The leaching of zinc also makes the fittings weaker, resulting in dezincification. In PEX pipes, the zinc build-up can cause your kitchen and bathroom fixtures to clog. It also causes fittings to crack or break, leaking water within your walls or underneath your house.
Which is better 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.
Should I use brass or plastic PEX fittings?
Brass its typically the best choice when the application demands a stronger fitting. In addition, plastic PEX fittings have a thicker wall requirement under ASTM2159 Standard, resulting in a reduced ID which restricts flow, while brass PEX fittings are manufactured to ASTM F1807 allowing for a larger flow passage.
Can you use SharkBite on PEX?
SharkBite brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and SDR-9 HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and SDR-9 HDPE. The PEX stiffener does not need to be removed for Copper or CPVC applications.
