These Pex Fittings & adapters are designed to connect two pieces of PEX piping together. The polyphenylsulfone (PPSU) material is safe for drinking water systems and strong enough to be installed in radiant heating applications.

Molded from Acudel Resin, PPSU is the highest performing polysulfone. It is known for its high toughness, high flexibility and tensile strength, and good resistance to chemicals and heat. PPSU is often an excellent choice for components that are exposed to high temperatures and corrosive media because of its exceptional chemical resistance.
