Pro-source 2555538165PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555538165PRO is a push-to-connect tube-to-universal-thread fitting manufactured from nickel-plated brass. It accepts 3/8 inch OD tubing on the push-in end and transitions to a 1/4 inch universal thread on the opposite end. Rated at 250 psi maximum working pressure, this fitting handles the pressure demands common in pneumatic and fluid distribution systems. The Buna O-ring provides a reliable seal across a working temperature range of 0 degrees F to 160 degrees F. Plumbers, HVAC technicians, and industrial maintenance technicians use this fitting when a fast, tool-free tube connection to a threaded port is required.

This fitting is suited for residential and light commercial pneumatic lines, compressed air distribution, and fluid transfer applications where a tube-to-threaded-port transition is needed. The push-to-connect design allows tubing to seat and lock without ferrules, compression nuts, or thread sealant on the tube side. It is a practical choice for control line work, instrument tubing runs, and similar low-to-medium pressure plumbing tasks. Sold in a package quantity of 5 units per order.

Compatibility

Designed as an OEM-style push-to-connect replacement or addition fitting for pneumatic and fluid systems using 3/8 inch OD tubing terminated to a 1/4 inch universal thread port.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance technicians. Depressurize and isolate the line before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect end; a ragged cut will compromise the O-ring seal. To release tubing, depress the collet ring before pulling the tube free.
