What is the difference between Type A and Type B PEX?

PEX A vs PEX B: Burst Pressure 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 is the difference between Type A and Type C 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. PEX C is created using the Electronic Irradiation, or Cold, method of cross-linking.

What is PEX B type?

PEX B. Technically referred to as a silane process, but is more often called steam or moisture cross-linking. Unlike the PEX-A process, it’s done after the HDPE is extruded into tube. Passing the finished product through steam in the presence of a silane catalyst encourages the polymers to form cross-links.

What is Type C PEX?

PEX C pipe is made using an electronic irradiation process to cross-link, known as “Cold cross-linking”. The cross-linking of the molecules is done after the process of extrusion by exposing the pipe to electron radiation.

Is SharkBite PEX type A or B?

Cross-linking is defined as polyethylene material that has undergone a change in molecular structure using a chemical or a physical process whereby the polymer chains are chemically linked. SharkBite non oxygen barrier pipe is manufacture as PEX-B and SharkBite oxygen barrier pipe is manufactured as PEX-C.

Is all Uponor PEX A?

Uponor manufactures PEX-a tubing is considered the superior type of PEX in the industry because the crosslinking is done during the manufacturing process when polyethylene is in its amorphic state (above the crystalline melting point).

What is PEX-C used for?

While PEX-C may be suitable for hydronic and radiant heating use, it offers little practical advantage over the other two types for hot and cold-water plumbing.

What is the difference between PEX a PEX B and PEX C?

PEX B pipe is made using Silane or moisture cure method of cross-linking, the links between the molecules of the HDPE form after the extrusion process using a catalyst and exposing the PEX pipe to hot water. PEX C pipe is made using an electronic irradiation process to cross-link, known as “Cold cross-linking”.

Can I use PEX-B fittings on PEX A?

There are two parts to this transition: the PEX-A MIP adapter and the PEX-B FIP adapter. These parts will thread together and allow you to join PEX-A to PEX-B. The PEX-A side will require an expansion ring while the PEX-B side requires the crimp ring.
