Compression Coupler Propane Fitting, 3/4"CTS-Compression

Compression Coupler Propane Fitting, 3/4"CTS-Compression X 3/4"CTS-Compression

The M750C17 Compression Coupler Propane Fitting is a Chicago Fittings 750PP Series plastic service coupling designed for plastic-to-plastic connections in natural gas and propane applications. Built with a Sealastic® rugged, leak-resistant design, it uses a molded rubber seal/ferrule assembly with an integral stiffener plus a bottoming nut (positive stop) to simplify installation. The self-seating, bi-directional seal/ferrule assembly helps eliminate the need for torque measurement, while the one-piece, CNC-machined solid bar stock construction and hex body make it easier to assemble with flat-jawed wrenches and reduce surface damage compared to bite-style tools.
