Coilhose Pneumatics 583 Pneumatic Hose Coupler 1/4 in Mnpt

Product Description

The COILHOSE PNEUMATICS 583 is a pneumatic hose coupler designed for industrial compressed air systems. It features a 1/4 inch male NPT (MNPT) threaded connection and a 3/8 inch body diameter, conforming to the Industrial Interchange standard — the most widely used coupler profile in North American shop and production environments. The body is steel with a nickel-plated finish for corrosion resistance. Rated to 300 psi maximum working pressure and a temperature range of -40 degrees F to 250 degrees F, this coupler handles the demands of continuous-duty pneumatic tool and equipment applications. Licensed HVAC techs, plumbers, electricians, and general contractors rely on this profile for air-powered tools at the job site or in the shop.

The 583 is suited for use in residential, commercial, and light industrial settings wherever Industrial Interchange pneumatic fittings are specified. It connects to air hose assemblies via the 1/4 inch MNPT thread and mates with any standard Industrial Interchange female coupler body. Typical applications include air compressor outlet connections, drop-line assemblies, and pneumatic tool quick-disconnect setups in both permanent and portable compressed air systems.

Compatibility

Designed as an OEM-style replacement or new-installation coupler for compressed air systems using the Industrial Interchange quick-disconnect standard with 1/4 inch MNPT threaded connections.

Installation Notes

Installation is typically performed by a pipefitter, plumber, or qualified maintenance technician. Depressurize and bleed the compressed air line completely before removing or installing any pneumatic fitting. Apply thread sealant tape (PTFE) to the MNPT threads per manufacturer and applicable code recommendations. Do not overtighten threaded connections; use a wrench and back-wrench as appropriate to avoid stressing downstream components.
