GasTite CSST 1/2" Coupler

GasTite CSST 1/2" Coupler

The XR3CPL-8 GasTite CSST 1/2" Coupler is a reusable brass coupling designed to splice or extend GasTite XR3 corrugated stainless steel tubing (CSST) in fuel gas installations. Its Jacket-Lock™ fitting design helps maintain electrical continuity by contouring the metal shield, while the tool-less flare design and self-guiding assembly make installation straightforward without special tools. With a metal-to-metal seal and no O-rings, gaskets, split rings, or inserts, it provides a reliable connection built for repeatable use.
