Coilhose Pneumatics 15C90B6F Pneumatic Coupler 1/4 in Brass

Product Description

The COILHOSE PNEUMATICS 15C90B6F is a brass Industrial Interchange pneumatic coupler designed for use in compressed air systems. It features a 1/4-inch body diameter with a 3/8-inch female NPT (FNPT) threaded connection, allowing it to mate with standard air hoses and fittings in industrial and shop environments. Rated for a maximum working pressure of 300 psi and a temperature range of -40 to 250 degrees F, this coupler handles the demands of daily compressed air service. Licensed HVAC techs, plumbers, mechanics, and general contractors regularly use Industrial Interchange couplers as a widely adopted standard across air tool and hose assemblies.

This coupler is suited for residential shops, commercial facilities, and light industrial environments wherever Industrial Interchange-pattern quick-connect air fittings are the shop standard. The threaded FNPT inlet connects directly to air hose ends, manifolds, or tool inlets with a matching male NPT fitting. Its brass construction makes it appropriate for applications requiring corrosion resistance and durability under repeated connect-disconnect cycles. Sold individually, it is a straightforward replacement or addition to any existing Industrial Interchange air system.

Compatibility

Designed as an OEM-style replacement or addition for Industrial Interchange compressed air systems using 3/8-inch FNPT threaded connections and 1/4-inch body couplers.

Installation Notes

Installation is performed by a qualified mechanic, pipefitter, or pneumatic systems technician. Always depressurize the air line fully before removing or installing any coupler. Apply thread sealant tape or compound to the FNPT threads per shop practice to prevent air leaks. Do not exceed the rated 300 psi working pressure for this fitting.
