Coilhose Pneumatics 122A 1/2 Inch Mnpt Pneumatic Coupler

Product Description

The COILHOSE PNEUMATICS 122A is a brass pneumatic hose coupler designed for Industrial Interchange pneumatic systems. It features a 1/2 inch male NPT (MNPT) threaded connection and a 1/2 inch body diameter, making it a standard-fit component for compressed air lines in shop and field environments. Rated to 300 psi maximum working pressure and operable across a temperature range of -40 degrees F to 250 degrees F, this coupler suits demanding service conditions. It is installed by HVAC technicians, pipefitters, and pneumatic system mechanics working on air tool lines, compressor drops, and distribution headers.

This coupler is suited for use in both residential and light commercial compressed air systems where Industrial Interchange compatibility is required. Common applications include air compressor outlet connections, inline hose assemblies, and tool drop lines in shop environments. The threaded MNPT connection allows direct installation into standard NPT female ports on compressor outlets, manifolds, and hose fittings. The brass construction resists corrosion in environments where moisture in the air supply is a factor.

Key Features

• Industrial Interchange coupler style for broad compatibility with standard pneumatic fittings
• 1/2 inch MNPT threaded connection for direct installation into NPT female ports
• Brass construction for corrosion resistance in moist compressed air environments
• 300 psi maximum working pressure rated for demanding shop air applications
• Wide service temperature range: -40 degrees F to 250 degrees F

Compatibility

Designed as an OEM-style replacement or new-installation coupler for Industrial Interchange pneumatic systems using 1/2 inch NPT threaded connections.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant tape or compound to the MNPT threads in accordance with the fitting manufacturer's guidelines and applicable piping codes. Do not overtighten brass fittings, as the material is subject to thread damage under excessive torque.
