3/8" CTS ProLock End Cap

ProLock Push-to-Connect End Caps are the easiest and most dependable way to cap Copper, PEX, or CPVC pipe in any combination with no solder, glue, or tools required. End caps are reusable and especially popular for pressure testing systems. JG ProLock fittings use a collet with stainless steel teeth that grips the pipe when fully inserted, and an EPDM O-Ring to provide a permanent, leak-proof seal. Disconnection is just as easy with no tools needed; simply depress the collet against the fitting and pull to remove. Lead-free, Full flow, & UV Resistant. ProLock Twist-to-Lock fittings are suitable for hot and cold potable water and hydronic heating applications. They have been specifically designed for the Professional Plumber. Code approved for behind-the-wall installations. 25-Years warranty. Specifications: 160 psi @ 73°F, 100 psi @ 180°F, 80 psi @ 200°F
