Coilhose Pneumatics 122 Pneumatic Coupler 1/2 Inch Mnpt

Product Description

The COILHOSE PNEUMATICS 122 is a 1/2 inch MNPT pneumatic coupler designed for industrial interchange air systems. Built from steel with a nickel-plated finish, it connects compressed air hoses and tools in demanding shop and field environments. The 1/2 inch body diameter and threaded NPT connection provide a secure, leak-resistant fit rated for pressures up to 300 psi. Operating temperature range spans -40 to 250 degrees F, making it suitable for both cold-weather outdoor work and high-cycle indoor installations. Industrial mechanics, maintenance technicians, and pneumatic system installers are the primary trades that specify this fitting.

This coupler is suited for use in industrial and commercial compressed air distribution systems where Industrial Interchange-style quick-connect fittings are the standard. Typical applications include assembly lines, vehicle service bays, maintenance facilities, and general-purpose air tool hookups requiring a reliable 1/2 inch threaded male connection. It mates with Industrial Interchange-style plugs commonly found throughout North American trade environments.

Key Features

• Industrial Interchange coupling type for broad compatibility with standard air tool plugs
• 1/2 inch MNPT threaded connection for direct pipe or hose-end installation
• 300 psi maximum working pressure for high-demand pneumatic circuits
• Steel construction with nickel-plated finish for corrosion resistance
• Wide operating range of -40 to 250 degrees F suits most shop and outdoor conditions
• 1/2 inch body diameter matches standard half-inch air line configurations

Compatibility

Designed as an OEM-style replacement or direct-install coupler for Industrial Interchange pneumatic systems using 1/2 inch MNPT threaded connections.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant tape or compound rated for compressed air to the NPT threads before tightening. Follow applicable OSHA and shop-safety guidelines for compressed air system work.
