Coilhose Pneumatics 110 Pneumatic Coupler 1/4 in Fnpt

Product Description

The COILHOSE PNEUMATICS 110 is a brass pneumatic coupler designed for high-flow compressed air applications. It features a 1/4-inch female NPT (FNPT) threaded connection and a 1/4-inch body diameter, making it a compact and reliable fitting for connecting air hoses and tools. Rated to 300 psi maximum working pressure and capable of handling temperatures from -40 to 250 degrees F, this coupler suits demanding shop and field environments. It is sold individually and is a direct fit for High Flow interchange systems.

This coupler is used in industrial, commercial, and professional shop settings where high-flow pneumatic tool connections are required. Typical installations include air compressor lines, manifolds, and hose assemblies used by automotive technicians, pipefitters, machinists, and general maintenance trades. The FNPT thread type allows straightforward connection to standard pipe-threaded ports on air supply equipment and fittings.

Key Features

• High Flow interchange type for increased airflow and reduced pressure drop
• 1/4-inch FNPT threaded connection for compatibility with standard pipe-threaded fittings
• Brass construction for corrosion resistance and durability in compressed air service
• 300 psi maximum working pressure rating
• Wide operating temperature range: -40 to 250 degrees F
• 1/4-inch body diameter — compact form factor for tight installations

Compatibility

Designed as a High Flow interchange-style replacement coupler for 1/4-inch FNPT pneumatic hose and tool connection points in compressed air systems.

Installation Notes

Installation is performed by qualified pneumatic or maintenance technicians. Before servicing or replacing any coupler, depressurize the air line completely and verify zero pressure with a gauge. Apply thread sealant tape appropriate for compressed air service to the FNPT threads before installation. Follow all applicable OSHA and local shop safety codes for compressed air system maintenance.
