Push-to-connect fittings for copper, PEX and CPVC, in 3/8" through 2". No tool, no solder, no crimp ring — the tube is pushed in and a stainless grab ring plus an O-ring hold and seal it.
They are the fastest repair fitting available and work on a wet line, which is why they live on service vans. The trade-off is cost per joint and the requirement that the tube be cut square, deburred and inserted to the full depth mark. A tube cut at an angle or left with a burr will cut the O-ring and leak later, not immediately.
Copper and CPVC must be deburred; PEX needs a stiffener insert on some brands and not others, so follow the specific manufacturer's instruction rather than assuming.
Most are rated for concealed use when installed to the listing, but some jurisdictions restrict them behind finished surfaces — worth confirming locally before closing a wall.
Bodies are lead-free brass. Stocked from SharkBite and Elkhart.
