The LEGRIS 3159 08 17 is a push-to-connect tube-to-male BSPT fitting designed for pneumatic and fluid-transfer plumbing applications. It accepts tubing with an 8mm outside diameter and connects to a male BSPT threaded port. The fitting body is constructed from nylon and is rated to 290 psi. An internal nitrile O-ring provides the primary seal at the threaded connection. Installation requires no tools on the tube side — the push-to-connect mechanism locks the tube in place on insertion and releases on retraction of the collet. This fitting is handled by plumbers, pipefitters, and pneumatic system technicians working on compressed-air, water, or compatible fluid lines.
This fitting is suited for light industrial, commercial, and OEM pneumatic or fluid-distribution systems where a quick tube-to-threaded-port connection is needed. The BSPT thread form is a parallel-sealing tapered thread common in European and Asian equipment, making this fitting a direct-fit solution for imported machinery, pneumatic control panels, and process equipment that specifies BSPT porting. Nylon construction keeps the fitting lightweight and resistant to corrosion in clean-air and low-contamination fluid environments.
Designed as an OEM-style push-to-connect BSPT male fitting for pneumatic and fluid-transfer plumbing systems that specify 8mm OD tubing and a 3/8 inch male BSPT threaded port.
Installation is performed by a licensed plumber, pipefitter, or qualified pneumatic technician. Depressurize and isolate the system completely before removing any existing fitting or inserting this one. Ensure the mating BSPT port is clean and free of debris before threading; apply thread sealant compatible with the service fluid on the BSPT threads as required by local code. Insert tubing fully into the collet until it bottoms out to ensure a leak-free seal, and perform a pressure test before returning the system to service.
