This insert is sold separately. Note 2: Speedfit fittings cannot be used on stainless steel pipe.DO NOT USE FOR gas, fuel oil or compressed air applications. John Guest Speedfit Push-to-Connect Couplers are the easiest and most dependable way to join Copper, PEX, or CPVC pipe in any combination with no solder, glue, or tools required. JG Speedfit 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. When twisted into place, the locking cap locks the pipe in place ensuring maximum security. Disconnection is just as easy with no tools needed; simply twist the cap counterclockwise to unlock then depress collet against the fitting to remove the pipe.
