Coilhose Pneumatics 582 Pneumatic Hose Coupler 3/8 in

Product Description

The COILHOSE PNEUMATICS 582 is a threaded pneumatic hose coupler designed for industrial compressed-air systems. It features a 3/8-inch body diameter and a 1/4-inch female NPT (FNPT) threaded connection, making it a standard-size fitting for shop air lines, pneumatic tools, and air distribution networks. Constructed from steel with a nickel finish, the 582 is built to handle a maximum working pressure of 300 psi and operating temperatures ranging from -40 degrees F to 250 degrees F. Licensed HVAC technicians, maintenance mechanics, and industrial service pros install this coupler as part of quick-disconnect fitting assemblies on compressed-air systems.

The 582 follows the Industrial Interchange (I/M) coupling standard, the most widely used quick-connect format in North American shops and industrial facilities. It is suited for residential shop setups, light manufacturing, and commercial maintenance environments where a reliable, pressure-rated coupler is needed for air tool connections, blow guns, or pneumatic hose assemblies. The FNPT thread type allows direct connection to standard pipe-threaded fittings and manifolds without adapters in most configurations.

Key Features

• Industrial Interchange (I/M) standard for broad tool and fitting compatibility
• 1/4-inch FNPT threaded inlet for standard pipe-threaded connections
• 3/8-inch body diameter rated to 300 psi maximum working pressure
• Steel construction with nickel finish for corrosion resistance
• Wide temperature range: -40 degrees F to 250 degrees F
• Compact, single-unit package suitable for replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation coupler for Industrial Interchange pneumatic quick-disconnect systems using 1/4-inch FNPT threaded connections.

Installation Notes

Installation is performed by qualified maintenance mechanics or pneumatic system technicians. Depressurize and bleed down the air line completely before removing or installing any coupling. Apply thread sealant or PTFE tape to the FNPT threads per standard practices, and tighten to fitting-manufacturer specifications using appropriate wrenches. Do not exceed the rated 300 psi working pressure or operating temperature limits of the coupler.
