Pro-source 2559014165PRO Push-to-connect Tube Stem Fitting

Product Description

The PRO-SOURCE 2559014165PRO is a push-to-connect tube-to-stem tube fitting designed for quick, tool-free connections in pneumatic and fluid transfer lines. Built from nickel-plated brass, it accepts tubing with a 5/32-inch outside diameter and connects to a stem with a 1/4-inch outside diameter. The fitting is rated for 250 psi service and is sealed with a Buna-N O-ring for reliable performance across a range of operating conditions. Plumbers, HVAC technicians, and pneumatic system installers use this fitting when a fast, secure tube connection is required without threading or soldering. Each package contains 5 fittings.

This fitting is suited for use in compressed air and water service lines, making it a practical choice in light commercial and residential mechanical systems. Typical applications include connecting flexible tubing to barbed or straight stems on manifolds, valves, control devices, and instrumentation ports. The push-to-connect design speeds up installation in tight or hard-to-reach locations where traditional fittings are impractical.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• Nickel-plated brass construction provides corrosion resistance in both air and water service
• Rated to 250 psi for use in compressed air and low-pressure water lines
• Buna-N O-ring seals for leak-resistant performance across typical service temperatures
• 5/32-inch tube OD inlet with 1/4-inch stem OD connection
• Packaged in quantities of 5 for multi-point installations

Compatibility

Designed for use with compressed air and water service lines requiring a 5/32-inch OD tube connection to a 1/4-inch OD stem.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pneumatic system mechanics. Depressurize and isolate the line completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely, free of burrs, before inserting into the push-to-connect port to guarantee a proper seal. Follow applicable codes including ASME and local mechanical codes when installing in pressurized systems.
