Norgren 124250428 Push-to-connect Male Adapter 1/4in

Product Description

The NORGREN 124250428 is a Pneufit push-to-connect male adapter fitting in a straight configuration, designed for pneumatic tubing systems. It connects 1/4 inch OD tubing to a 1/4 inch male NPTF threaded port, providing a fast, tool-free tube connection on one end and a threaded seal on the other. The body is nickel-plated brass, rated for a maximum working pressure of 260 psi. This fitting is used by industrial maintenance technicians, HVAC mechanics, and pneumatic system installers who need a reliable, leak-free connection without compression sleeves or ferrules.

This adapter is suited for compressed air and pneumatic control lines in light industrial, commercial HVAC, and process automation applications. The straight geometry makes it a direct in-line connector where tubing must terminate into a male NPT port on a valve, manifold, cylinder, or instrument. The push-to-connect design allows rapid tube insertion and release, reducing installation time in panel builds and field service work.

Key Features

• Push-to-connect tube end accepts 1/4 inch OD tubing without tools or ferrules
• 1/4 inch NPTF male thread for a pressure-tight seal into female NPT ports
• Nickel-plated brass construction resists corrosion in typical pneumatic service environments
• Rated to 260 psi maximum working pressure
• Operating temperature range of -4 degrees F to 175 degrees F
• Vacuum-capable to 29.5 inches Hg for low-pressure vacuum circuit use

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic tubing systems using 1/4 inch OD tube and 1/4 inch female NPT port connections.

Installation Notes

Installation is performed by licensed pipefitters, HVAC mechanics, or qualified pneumatic technicians. De-energize and depressurize the pneumatic system fully before removing or installing any fittings. Ensure the tube end is cut square and deburred before insertion to achieve a proper seal. Thread engagement should follow NPTF hand-tight-plus practice per applicable piping codes; do not overtighten, as this is a brass fitting.
