Tru-flate 13-235 Push-to-connect Air Coupler 1/4 in Fnpt

Product Description

The TRU-FLATE 13-235 is a push-to-connect air line coupler designed for industrial and Milton-series pneumatic systems. It features a 0.25-inch female NPT (FNPT) inlet and uses a tubular valve construction that promotes greater airflow compared to standard poppet-style couplers. The 13-235 delivers a 100% air-tight seal and includes accidental disconnect protection to keep the air line secured under working pressure. Weighing 0.196 pounds, it is a compact, durable fitting suited for use on compressors, blow guns, impact wrenches, and other pneumatic tools common in shop and field environments.

This coupler is intended for use in industrial pneumatic applications where reliable, leak-free connections are required. The push-to-connect design allows for fast tool changes without the need for additional hardware. It fits standard 0.25-inch FNPT threaded ports found on a wide range of air-line accessories, manifolds, and compressor outlets. Both shop technicians and field service professionals regularly install this style of coupler on fixed and portable compressed-air systems.

Key Features

• 100% air-tight seal prevents pressure loss at the connection point
• Accidental disconnect protection keeps the line secured under load
• Tubular valve construction promotes higher airflow than standard poppet designs
• Push-to-connect mechanism allows fast, tool-free plug insertion and removal
• 0.25-inch FNPT threading for compatibility with standard air-line fittings

Compatibility

Designed as an OEM-style replacement or upgrade coupler for industrial and Milton-series pneumatic systems using 0.25-inch FNPT connections.

Installation Notes

Installation should be performed by a qualified technician with the compressed-air system fully depressurized and the compressor shut off before handling any fittings. Apply thread sealant tape to the FNPT threads in accordance with standard plumbing and pneumatic practices before tightening. Inspect the coupler body and O-ring for damage before putting the line back into service. Follow applicable shop safety guidelines and local codes when working on compressed-air systems.
