The new patent pending AutoSnap® fittings are the only CSST fittings that do not require any disassembly or reassembly of the fitting to the TracPipe® Counterstrike® CSST. This greatly reduces installation difficulty and time as there are no small loose gaskets, O-rings or retainer rings to contend with in a dark and/or cold work place environment! AutoSnap is CSA listed and features a metal to metal cup seal without any exposed stainless steel pipe behind the new fitting. Reduced torque value and reusability all make for an optimum installer friendly fitting.
