Coilhose Pneumatics 584 Pneumatic Hose Coupler 3/8 in

Product Description

The COILHOSE PNEUMATICS 584 is a threaded pneumatic hose coupler designed for use in compressed air systems across industrial and commercial applications. Built from steel with a nickel-plated finish, this coupler features a 3/8-inch body diameter and a 1/2-inch female NPT (FNPT) threaded connection. It conforms to the Industrial Interchange standard, the most widely used coupler interchange type in North American pneumatic systems. Rated to 300 psi maximum working pressure, it handles the demands of shop air tools, air-operated equipment, and production line pneumatic circuits. Licensed HVAC techs, mechanics, and industrial maintenance technicians install this type of fitting as part of compressed air distribution and tool connection assemblies.

The 584 coupler is suited for both residential shop and commercial industrial environments where Industrial Interchange compatibility is required. Its FNPT thread accepts standard 1/2-inch male pipe-threaded fittings, making it a straightforward drop-in component for compressed air hose assemblies, manifolds, and quick-connect stations. The nickel-plated steel construction resists corrosion in typical shop air environments. This coupler ships individually and is appropriate for single-point replacement or new assembly builds.

Key Features

• Industrial Interchange standard for broad compatibility with common North American pneumatic fittings
• 1/2-inch FNPT threaded connection for secure, leak-resistant installation
• 3/8-inch body diameter coupler size
• 300 psi maximum working pressure rating
• Steel construction with nickel-plated finish for corrosion resistance
• Sold individually — no minimum order beyond single unit

Compatibility

Designed as an OEM-style Industrial Interchange coupler compatible with standard 1/2-inch FNPT compressed air hose and fitting assemblies. Specific system or model compatibility was not provided in the product data.

Installation Notes

This coupler is installed by mechanics, pipefitters, or industrial maintenance technicians working on compressed air distribution systems. Depressurize and bleed the air line completely before removing or installing any pneumatic fitting. Apply thread sealant tape or compound rated for compressed air service to the FNPT threads before tightening. Do not exceed the 300 psi maximum working pressure rating of this fitting in the assembled system.
