Norgren 124250528 Push-to-connect Male Adapter 5/16 Od

Product Description

The NORGREN 124250528 is a Pneufit push-to-connect male adapter fitting designed for pneumatic tubing systems. It creates a fast, tool-free connection between 5/16-inch OD tubing and a 1/4-inch NPTF male threaded port. The body is nickel-plated brass, rated to a maximum working pressure of 260 psi. This fitting is installed by HVAC technicians, pneumatic system mechanics, and industrial maintenance trades wherever a reliable tube-to-male-NPT transition is needed. The push-to-connect design eliminates compression sleeves and ferrules, reducing assembly time on pneumatic control lines and instrument air circuits.

This fitting is suited for pneumatic control systems, instrument air lines, and compressed air distribution in both light industrial and commercial HVAC applications. It accommodates 5/16-inch OD tubing with a 1/4-inch NPTF threaded male end. The working temperature range of -4 degrees F to 175 degrees F makes it appropriate for indoor mechanical rooms and light-duty outdoor pneumatic panels where temperature extremes remain moderate. It is commonly used in control valve actuator lines, air pilot circuits, and building automation pneumatic runs.

Key Features

• Push-to-connect design accepts 5/16-inch OD tubing without ferrules or compression nuts
• 1/4-inch NPTF male thread for a pressure-tight connection at the port end
• Nickel-plated brass body for corrosion resistance in moist mechanical environments
• 260 psi maximum working pressure rating
• Temperature range: -4 degrees F to 175 degrees F
• Compact overall length of 1.23 inches for tight-clearance installations

Compatibility

Designed as an OEM-style push-to-connect male adapter for pneumatic tubing systems using 5/16-inch OD tubing and 1/4-inch NPTF male threaded ports.

Installation Notes

Depressurize and lock out the pneumatic circuit before replacing or installing this fitting. Ensure tubing is cut cleanly and squarely, with no burrs, before inserting into the push-to-connect collet. Apply thread sealant compatible with brass fittings to the NPTF male threads per the applicable system specification. Verify that tubing OD matches the 5/16-inch rating before final pressurization.
