Norgren 104251048 Push-to-connect Straight Adapter Fitting

Product Description

The NORGREN 104251048 is a straight push-to-connect adapter fitting designed to join tube lines to a male NPT port and back to tube in a single inline connection. Constructed from nickel-plated brass with a nitrile O-ring, this fitting handles working pressures up to 260 psi and operates across a temperature range of 0 degrees F to 175 degrees F. The push-to-connect mechanism on both tube ends allows for tool-free tube insertion, reducing installation time on compressed air, pneumatic control, and general-purpose fluid lines. The male thread is NPTF, providing a pressure-tight seal on tapered pipe thread ports.

This fitting is suited for general-purpose pneumatic and fluid system applications in both residential and light commercial settings. Typical installations include compressed air distribution lines, pneumatic control panels, and instrument tubing runs where a tube-to-NPT-to-tube inline adapter is required. The 10 mm tube outside diameter and 1.2 inches overall body length make it appropriate for compact manifold and inline plumbing configurations. Plumbing and mechanical contractors, as well as HVAC and industrial service technicians, commonly install this type of fitting.

Key Features

• Push-to-connect ends on both tube ports allow tool-free tube insertion and release
• Nickel-plated brass construction for corrosion resistance in general-purpose pneumatic service
• NPTF male thread provides pressure-tight seal on tapered pipe thread ports
• Rated to 260 psi maximum working pressure
• Nitrile O-ring for reliable sealing across the rated temperature range
• Compact straight inline design with 1.45 inch overall length

Compatibility

Designed for general-purpose pneumatic and fluid line applications using 10 mm outside diameter tubing with NPTF male pipe thread connections.

Installation Notes

Depressurize and isolate the system completely before removing or installing any fitting. Ensure tubing is cut squarely and deburred before insertion into the push-to-connect ports to achieve a proper seal. NPTF threads are self-sealing by thread deformation; verify thread engagement is sufficient before pressurizing. Installation should be performed by a qualified plumbing or mechanical technician in accordance with applicable local codes and system pressure ratings.
