Norgren 121250628 Straight Adapter 3/8in Od 1/4in Bspt

Product Description

The NORGREN 121250628 is a push-to-connect straight adapter fitting designed to join pneumatic or fluid tubing to a male BSPT threaded port in a single inline configuration. Constructed from nickel-plated brass, it accepts 3/8 inch outside diameter tubing on the push-to-connect end and threads into a 1/4 inch BSPT male port on the opposite end. Rated to 260 psi maximum working pressure, this fitting is suited for compressed air lines, pneumatic control circuits, and light fluid distribution systems. The push-to-connect mechanism allows fast, tool-free tube insertion, reducing installation time on production equipment, HVAC controls, and industrial pneumatic panels.

This adapter is used in applications where a rigid or semi-rigid tube must terminate directly into a BSPT-threaded valve, manifold, cylinder, or instrument port. Typical install environments include industrial automation, pneumatic actuation systems, compressed air distribution, and building automation control panels. The straight configuration keeps plumbing compact where inline transitions are needed. Operating temperature range spans -4 degrees F to 176 degrees F, making it suitable for year-round indoor and light industrial service conditions.

Key Features

• Push-to-connect tube end accepts 3/8 inch OD tubing without tools or ferrules
• 1/4 inch BSPT male thread for direct installation into standard British Standard Pipe Taper ports
• Nickel-plated brass construction resists corrosion in compressed air and light fluid service
• 260 psi maximum working pressure rating for pneumatic and low-pressure fluid circuits
• 29.5 in-Hg vacuum rating supports vacuum line applications
• Wide temperature range of -4 degrees F to 176 degrees F covers most indoor and light industrial environments

Compatibility

Designed as an OEM-style push-to-connect straight adapter for pneumatic tubing systems using 3/8 inch OD tube and 1/4 inch BSPT male threaded ports.

Installation Notes

This fitting is typically installed by instrumentation technicians, pipefitters, or HVAC controls technicians working on pneumatic systems. Depressurize and lock out the air supply before removing or installing any fittings. Ensure the mating BSPT port thread form is confirmed before installation, as BSPT is not interchangeable with NPT threads. To seat the push-to-connect end, insert clean, burr-free tubing with a square-cut end firmly until it bottoms out in the collet.
