Coilhose Pneumatics 340A 3/4 Inch Brass Pneumatic Hose Coupler

Product Description

The COILHOSE PNEUMATICS 340A is a brass pneumatic hose coupler designed for industrial compressed air systems. It features a 3/4 inch female NPT (FNPT) threaded connection and a 3/4 inch body diameter, conforming to the Industrial Interchange standard widely used in production and maintenance environments. Rated to 300 psi maximum working pressure and tested across a temperature range of -40 to 250 degrees F, the 340A handles the demands of continuous shop-floor use. Licensed contractors and industrial maintenance technicians install this coupler to connect hose assemblies to air lines, tools, and supply manifolds.

The 340A is suited for use in compressed air distribution systems in light industrial, heavy manufacturing, and commercial maintenance applications. Its Industrial Interchange profile makes it compatible with the broad range of couplers and plugs that conform to that standard, which is among the most common formats found on production floors, service trucks, and maintenance facilities across North America. The threaded FNPT connection accepts standard pipe fittings and adapters, supporting straightforward integration into existing pneumatic circuits.

Compatibility

Designed for use with Industrial Interchange standard pneumatic plugs and hose assemblies. Compatible with any compressed air system utilizing 3/4 inch FNPT pipe connections and Industrial Interchange format couplers.

Installation Notes

Installation is typically performed by a qualified maintenance technician or pipefitter working on compressed air distribution systems. Depressurize and lock out the air supply before removing or installing any coupler. Apply thread sealant appropriate for pneumatic service to the FNPT threads before assembly. Verify that system pressure does not exceed the 300 psi rated working pressure of this coupler.
