Are all PEX crimp fittings the same?

Are all PEX crimp fittings the same?

PEX crimp and PEX clamp connections use the same fittings, normally referred to as “crimp” or “barbed” PEX fittings. 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.

Which is better PEX cinch or crimp?

The stainless steel Cinch Clamps are stronger than the copper Crimp Rings. I know this from personal experience after working with frozen water lines. When the fitted connection freezes with water in the line it will cause the copper Crimp Ring to expand just enough to cause a leak when it thaws.

What is better PEX Clamp or PEX crimp?

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.

Are PEX crimp tools universal?

This universal PEX crimping tool will work with all stainless steel crimps of sizes ranging from ⅜ of an inch to 1 inch. If you need to calibrate your tool, no need to worry because the tool to do so is included.

How can you tell the difference between 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.

What is the difference between PEX A and PEX B?

Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.

What is the flow rate of 1/2 PEX pipe?

At a design velocity of 8 feet per second (fps) in a ½” PEX system, water velocity will reach at least 12.7 fps and as high as 19 fps, depending on the type of fitting used.

What is the Standard Dimension Ratio for PEX pipe?

PEX made to US standards must comply with a SDR-9 (Standard Dimension Ratio), which is the ratio of OD (Outside Diameter) to pipe wall thickness (9:1). Exceptions are nominal sizes 1/2″ and below.

What is CTS size of PEX pipe?

PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). OD of PEX, copper and CPVC pipe with the same size (CTS) is the same. This is why push fittings can be used with all of these pipes.

What are the dimensions of a PEX tub?

How close together can you run parallel runs of PEX pipe?

Parallel runs of pipe can be spaced as close as necessary. Typical elongation is anywhere from 1″ to 2.5″ for every 100ft of PEX pipe at a 10°F temperature rise. Since PEX expands and contracts with temperature changes, it should be secured so as to provide sufficient space for expansion to occur.
