Norgren 121250428 Push-to-connect Tube Fitting Adapter

Product Description

The NORGREN 121250428 is a straight push-to-connect tube-to-male BSPT adapter fitting designed for pneumatic and fluid-conveyance plumbing assemblies. Constructed from nickel-plated brass, it accepts 1/4-inch outside-diameter tubing on one end and threads into a 1/4-inch BSPT male port on the other. The push-to-connect mechanism allows fast, tool-free tube insertion while maintaining a rated working pressure of 260 psi. At 0.99 inches in overall length and 0.05 pounds, it is a compact inline adapter suited to tight manifold and panel installations. Licensed plumbers, pipefitters, and pneumatic system technicians typically install this type of fitting.

This fitting is appropriate for use in compressed-air distribution lines, pneumatic control circuits, and fluid-handling systems that terminate in BSPT-threaded ports. It supports operating temperatures from -4 degrees F to 176 degrees F, making it suitable for both indoor and light industrial environments. The 29.5 in-Hg vacuum rating also allows use in low-pressure vacuum applications. Single-piece packaging makes it convenient for service calls and one-off panel builds where a single adapter is needed.

Key Features

• Push-to-connect tube end accepts 1/4-inch OD tubing without tools
• 1/4-inch BSPT male thread for direct port connection
• 260 psi maximum working pressure rating
• Nickel-plated brass construction for corrosion resistance
• Vacuum-rated to 29.5 in-Hg for low-pressure suction service
• Compact 0.99-inch overall length for space-constrained installations

Compatibility

Designed as an OEM-style inline adapter for pneumatic and fluid-system assemblies that use 1/4-inch OD tubing and 1/4-inch BSPT male threaded ports.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified pneumatic systems technician. Depressurize and lock out the system before replacing or installing any inline fitting. Ensure the BSPT thread is compatible with the receiving port — BSPT is a parallel thread standard and requires a sealing method such as thread-seal tape or a compatible O-ring face seal. Verify tube cut is clean and square before inserting into the push-to-connect end to ensure a leak-free grip.
