Pro-source 2558014865PRO Push-to-connect Fitting 1/4 Od 5 Pack

Product Description

The PRO-SOURCE 2558014865PRO is a push-to-connect tube fitting with a female NPT port, designed for quick, tool-free tube connections in pneumatic and fluid distribution systems. Constructed from nickel-plated brass, it handles working pressures up to 250 psi and operating temperatures from 0 degrees F to 160 degrees F. The fitting accepts 1/4 inch OD tubing on both tube ends and threads onto 1/8 inch NPTF female ports, making it a compact inline connector. A Buna O-ring provides a reliable seal across both compressed air and water service applications. Each package contains 5 fittings.

This fitting is suited for residential and light commercial HVAC, refrigeration, compressed air distribution, and plumbing applications where push-to-connect convenience is needed at an NPT branch or instrument port. Typical installations include air handler drain lines, pneumatic control circuits, water supply connections, and compressed air manifold branches. The connection type — tube by FNPT by tube — allows it to serve as an inline tee or pass-through connector at a threaded port without additional tools for the tube side.

Key Features

• Push-to-connect design on both tube ends — no ferrules, sleeves, or tools required for tube insertion

• Rated to 250 psi maximum working pressure
• Temperature range of 0 degrees F to 160 degrees F covers typical HVAC and compressed air environments
• Buna O-ring sealing material compatible with compressed air and water media
• 1/8 inch NPTF female thread provides a pressure-tight connection at the NPT port
• Sold in a 5-pack for multi-point or service-stock use

Compatibility

Designed for use with compressed air and water systems requiring 1/4 inch OD tubing and 1/8 inch NPTF female threaded ports. Suitable as an OEM-style or aftermarket fitting in pneumatic controls, HVAC instrumentation, and light-duty plumbing distribution lines.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pipefitters working on low-pressure air or water circuits. Shut off the compressed air supply or isolate the water line and relieve system pressure before removing or installing any fitting. Ensure the 1/8 inch NPTF male port is clean and free of debris before threading the fitting; apply thread sealant appropriate for the service medium in accordance with applicable plumbing or mechanical codes. To insert tubing, push the tube firmly and squarely into the fitting until it seats; to release, depress the collet ring while withdrawing the tube.
