What are the different types of PEX tubing?

What are the different types of PEX tubing?

If you’ve ever shopped for PEX tube you probably know there are three main types. These are PEX A, PEX B and PEX C. In hindsight, that’s an unfortunate naming scheme, because it makes it sound like these are grades and implies that one is better or worse than the other.

What is Uponor PEX pipe?

What is Uponor PEX? Uponor PEX plumbing systems is a flexible, durable plastic piping product called crosslinked polyethylene (PEX) tubing used to distribute the water throughout your home. PEX tubing is a clean, non-toxic, and extremely durable piping product that will not pit, scale or corrode.

Is uponor the same as PEX?

Uponor (formerly Wirsbo) has been making PEX pipe for radiant floor heating since 1970, longer than any other PEX manufacturer.

Is PEX A or B better?

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. PEX-B is a clear winner in terms of price vs. both other types.

How can you tell PEX B from PEX A?

How to identify PEX pipe

  1. Check the label. If you look closely at the pipe, you will see information printed on the side.
  2. The second way is to identify the style of fittings. PEX-B will have metal rings — either cramp or clamp — whereas the PEX-A uses an expansion ring made out of PEX or a similar material.

Is ProPEX the same as PEX?

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. It’s a proprietary brand of PEX connections and pipe invented by an international company named Uponor (uponor.ca) and based in Finland.

What is the ODOD of PEX pipe?

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. 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).

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 advantages of using PEX tubing?

It is flexible, resistant to scale and chlorine, doesn’t corrode or develop pinholes, is faster to install than metal or rigid plastic, and has fewer connections and fittings. PEX tubing is made from crosslinked HDPE (high density polyethylene) polymer.

How much does PEX pipe elongate?

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.
