PEX (cross-linked polyethylene) pipe fittings are made from the same material as PEX pipes: cross-linked polyethylene. This material undergoes a process that links the individual polyethylene molecules to create a three-dimensional network, enhancing the properties of the polymer. There are three primary types of PEX, distinguished by the method used to crosslink the polyethylene molecules:
PEX-A (Engel Method):

PEX (cross-linked polyethylene) pipe fittings are made from the same material as PEX pipes: cross-linked polyethylene. This material undergoes a process that links the individual polyethylene molecules to create a three-dimensional network, enhancing the properties of the polymer. There are three primary types of PEX, distinguished by the method used to crosslink the polyethylene molecules:
PEX-A (Engel Method):
Produced using the Engel method, which involves the peroxide method of crosslinking. This results in a more uniform and stronger crosslinking structure throughout the material. PEX-A tends to be the most flexible type and has better shape memory, meaning it can return to its original shape after being expanded or bent.
PEX-B (Silane Method):
Manufactured using the silane method of crosslinking. It is crosslinked after the extrusion process. PEX-B is slightly less flexible than
PEX-A but is still highly durable and commonly used in plumbing systems.
PEX-C (Electron Beam or Radiation Method):
Produced by exposing the polyethylene material to electron beam radiation. This method allows for crosslinking after the extrusion process. PEX-C is known for its resistance to stress cracking and has properties similar to PEX-B.
Regardless of the specific type, PEX
pipe fittings are known for their durability, flexibility, and resistance to corrosion and scale. They are designed to efficiently connect PEX pipes using various connection methods like crimping, clamping, or push-fit systems, providing a reliable and watertight seal. The material's characteristics make PEX fittings a popular choice for a wide range of plumbing applications, from residential to commercial use.
