Pro-source 2557053065PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2557053065PRO is a push-to-connect tube fitting designed for fast, tool-free connections in pneumatic and fluid lines. It features a tube-to-universal-thread configuration with a 10-32 thread size and accepts tubing with a 5/32-inch outside diameter. The body is nickel-plated brass, offering corrosion resistance suitable for compressed air and water service. Rated to 250 psi maximum working pressure, this fitting handles a wide range of light-duty pneumatic applications. The Buna O-ring provides a reliable seal across a service temperature range of 0 degrees F to 160 degrees F. Plumbers, pneumatic system technicians, and instrumentation techs install this type of fitting during assembly or repair of small-bore tubing runs.

This fitting is intended for use with compressed air and water systems where small-diameter tubing connects to threaded ports. The 10-32 universal thread makes it compatible with a broad range of valves, manifolds, regulators, and instrumentation bodies that use that thread standard. Typical install scenarios include control panel pneumatic circuits, light industrial equipment, and laboratory or instrumentation tubing assemblies. Each package contains 5 fittings, making it practical for multi-point installations or keeping spares on hand during a service call.

Compatibility

Designed for use with compressed air and water systems utilizing 5/32-inch OD tubing and 10-32 universal threaded ports. Suitable for pneumatic control circuits, instrumentation assemblies, and light industrial fluid lines.

Installation Notes

Installation is performed by pneumatic system technicians, instrumentation technicians, or licensed plumbers depending on the application. Before installing or removing fittings, depressurize the line completely and verify zero pressure at the connection point. Tubing should be cut cleanly and squarely — use a dedicated tube cutter rather than a blade — to ensure a proper seal against the O-ring. Confirm thread engagement is complete before restoring system pressure and inspect for leaks at startup.
