SharkBite 10 Pack 3/4" Poly Alloy Barb Insert Pex Coupling is designed for cross-linking polyethylene tubing used in hot and cold water systems. It is compatible with True Value #608-933 cinch clamps and requires a cinch tool (True Value #608-743) or copper crimp rings for installation on cross-linked polyethylene PEX tubing. After crimping, each fitting can be immediately tested to over 100 PSI. These NSF-listed poly alloy inserts serve as replacements for brass PEX insert fittings, complying with California AB1953 and Vermont S152 low lead laws. Connect two pieces of the same-sized PEX pipe together using crimp or clamp rings, ensuring a secure and durable connection. Made from high-performance Acudel Polymer, this coupling is corrosion-resistant and certified for use in potable water and hydronic heating system applications.
