Norgren 121250618 Push-to-connect Straight Adapter Fitting

Product Description

The NORGREN 121250618 is a straight push-to-connect adapter fitting designed to connect 3/8 inch OD tubing to a 1/8 inch male BSPT threaded port. Constructed from nickel-plated brass, this fitting handles maximum working pressures up to 260 psi and operating temperatures ranging from -4 degrees F to 176 degrees F. It also carries a vacuum rating of 29.5 inches Hg, making it suitable for both pressure and vacuum applications. The overall installed length is 1.25 inches. HVAC technicians, plumbers, and pneumatic system installers use this fitting where a quick, reliable tube-to-male-thread connection is required without additional tools on the tube side.

This adapter is suited for use in compressed air, pneumatic control, and fluid handling systems that require a transition from push-to-connect tubing to a BSPT male threaded port. Typical applications include pneumatic actuators, instrumentation lines, and HVAC control tubing runs in both light commercial and industrial settings. The push-to-connect design allows fast field assembly and reduces installation time on multi-fitting manifolds or panel builds.

Key Features

• Push-to-connect tube end accepts 3/8 inch OD tubing with no additional tools required
• 1/8 inch male BSPT thread on the port end for direct threaded connection
• Nickel-plated brass construction for corrosion resistance in pneumatic and fluid service
• Rated to 260 psi maximum working pressure
• Vacuum-rated to 29.5 inches Hg for suction-side applications
• Compact overall length of 1.25 inches for tight installation spaces

Compatibility

Designed as a standard push-to-connect straight adapter for pneumatic and fluid control systems using 3/8 inch OD tubing and 1/8 inch BSPT male threaded ports.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid system assembly. Depressurize and isolate the system fully before removing or installing any fittings. Ensure the BSPT male threads are sealed with an appropriate thread sealant or PTFE tape rated for the service fluid and pressure before tightening. Insert tubing fully into the push-to-connect end until it seats, and verify a secure connection by applying light pull-back force on the tube before returning the system to service.
