Coilhose Pneumatics 15C90B4F 1/4 Inch Brass Pneumatic Coupler

Product Description

The COILHOSE PNEUMATICS 15C90B4F is a brass pneumatic hose coupler designed for compressed-air distribution systems in industrial and commercial service environments. It features a 1/4 inch female NPT (FNPT) threaded connection and a 1/4 inch body diameter, conforming to the Industrial Interchange standard — the most widely adopted coupler format in North American trade shops. Rated to 300 psi maximum working pressure and suitable for temperatures ranging from -40 degrees F to 250 degrees F, this coupler handles demanding shop-air and pneumatic-tool applications. Brass construction provides corrosion resistance and reliable sealing across the rated temperature range. Installed by HVAC technicians, pipefitters, and general maintenance trades wherever threaded pneumatic connections are required.

This coupler is suited for use in shop-air systems, pneumatic tool lines, and compressed-air distribution manifolds in both residential service vehicles and commercial facilities. The Industrial Interchange profile ensures broad compatibility with standard pneumatic plugs and fittings found throughout North American trade environments. The FNPT thread allows direct connection to standard pipe fittings, hose barbs, and manifold ports without adapters in most installations.

Key Features

• Industrial Interchange coupler profile — compatible with the most common pneumatic plug standard in North America
• 1/4 inch FNPT threaded connection for direct pipe and fitting attachment
• 300 psi maximum working pressure rating for shop-air and pneumatic-tool service
• Operating temperature range: -40 degrees F to 250 degrees F
• Brass body construction for corrosion resistance and durability
• 1/4 inch body diameter — compact form for tight panel or manifold installations

Compatibility

Designed as an OEM-style replacement or new-installation coupler for Industrial Interchange pneumatic systems using 1/4 inch FNPT threaded connections in compressed-air service.

Installation Notes

Shut down and bleed all air pressure from the pneumatic line before removing or installing any coupler. Apply thread sealant tape or paste rated for compressed-air service to the FNPT threads before assembly. Tighten to snug plus a turn — do not overtighten brass fittings, as the material is susceptible to thread damage under excess torque. Pneumatic fitting work in commercial facilities may be subject to OSHA 29 CFR 1910.169 compressed-air system requirements; verify compliance before placing the system back in service.
