The PRO-SOURCE 2557504665PRO is a push-to-connect tube fitting with a tube-to-female BSPP tube-to-female connection configuration, constructed from nickel-plated brass. It accepts 4 mm outside diameter tubing on each push-to-connect end and threads into a 1/8 inch BSPP female port. Rated for a maximum working pressure of 250 psi, this fitting handles both compressed air and water service. The Buna O-ring seals support a temperature range of 0 degrees F to 160 degrees F, making it suitable for a broad range of industrial and mechanical service environments. It is installed by plumbers, pipefitters, and mechanical technicians working on pneumatic or fluid distribution systems.
This fitting is used in compressed air distribution, water service lines, and general fluid transfer applications where a push-to-connect interface connects to a BSPP-threaded female port. The tube-in, thread-out configuration suits panel-mount or manifold installations where quick tube insertion is needed on one or both ends. Sold in a package quantity of 5, it is appropriate for both new installations and service work requiring multiple fittings at a single job site. It is suited for light industrial, commercial, and OEM equipment applications.
Designed for use with compressed air and water systems requiring a push-to-connect tube fitting with a 1/8 inch BSPP female threaded port and 4 mm outside diameter tubing.
Shut off and depressurize the system before replacing or installing any push-to-connect fitting. Confirm that tubing outside diameter matches the 4 mm specification and that tube ends are cleanly cut and free of burrs before insertion. Thread engagement should be made by hand first to avoid cross-threading the BSPP port; use thread sealant appropriate for the service fluid as required by applicable codes. Inspect the Buna O-ring and push-to-connect collet for damage prior to installation.
