Coilhose Pneumatics 120A 1/2 Inch Fnpt Pneumatic Coupler

Product Description

The COILHOSE PNEUMATICS 120A is a brass pneumatic hose coupler designed for industrial compressed air systems. It features a 1/2 inch female NPT (FNPT) threaded connection and a 1/2 inch body diameter, conforming to the Industrial Interchange standard — the most widely used coupler style in North American shops and industrial facilities. 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 heavy-use pneumatic tool and equipment hookups. HVAC technicians, plumbers, pipefitters, and general contractors install it wherever a reliable threaded coupler connection is required on a compressed air line.

The 120A is suited for use on stationary air compressors, portable compressor rigs, pneumatic tool manifolds, and shop air distribution systems in both residential service and commercial or light industrial settings. The Industrial Interchange profile accepts mating plugs from most major pneumatic tool and accessory brands that follow the same interchange standard, making it a practical replacement or added connection point in existing systems.

Key Features

• Industrial Interchange coupler profile — compatible with the most common pneumatic plug standard in North American shops
• Brass construction for corrosion resistance and durability in compressed air service
• 1/2 inch FNPT threaded connection for direct pipe or fitting installation
• Maximum working pressure of 300 psi handles high-demand pneumatic tool applications
• Operating temperature range of -40 to 250 degrees F suits indoor and outdoor installations

Compatibility

Designed as a replacement or supplemental coupler for compressed air systems using the Industrial Interchange standard with 1/2 inch FNPT threaded connections.

Installation Notes

Installation is performed by a qualified trades professional or experienced DIYer familiar with compressed air systems. Depressurize and lock out the air supply before removing or installing any coupler. Apply thread sealant tape or compound to the FNPT threads per standard plumbing practice to ensure a leak-free connection. Verify that the system operating pressure does not exceed the 300 psi rated maximum of this coupler.
