Coilhose Pneumatics 5802 Pneumatic Hose Coupling 3/8 in

Product Description

The COILHOSE PNEUMATICS 5802 is a steel pneumatic hose coupling connector designed for industrial compressed-air systems. It features a 3/8-inch female NPT (FNPT) threaded connection and a 3/8-inch body diameter, finished in nickel plating for corrosion resistance. This coupling follows the Industrial Interchange standard, making it widely compatible across industrial pneumatic tool setups. It is installed by HVAC technicians, pipefitters, maintenance mechanics, and other trades professionals who build or service compressed-air distribution lines and pneumatic tool drops.

This connector is suited for industrial and light commercial compressed-air applications where Industrial Interchange couplings are the shop or facility standard. Typical uses include connecting air hoses to manifolds, quick-disconnect lines, and pneumatic tool supply ports. The threaded FNPT design allows direct installation into female-threaded ports on air hose assemblies, distribution headers, and inline fittings. It is a single-piece connector sold individually.

Key Features

• Industrial Interchange coupling type — compatible with the most widely used pneumatic quick-connect standard in shop and industrial environments
• 3/8-inch FNPT threaded connection for direct installation into standard female-threaded ports
• 3/8-inch body diameter matches common air hose and fitting sizes
• Steel construction with nickel-plated finish for durability and corrosion resistance
• Lightweight at 0.13 pounds — minimal added load on hose assemblies

Compatibility

Designed as an OEM-style replacement or addition for industrial compressed-air systems using Industrial Interchange standard pneumatic couplings with 3/8-inch FNPT threaded connections.

Installation Notes

Installation is performed by qualified mechanics or trades professionals working on compressed-air systems. Depressurize and bleed the air supply line completely before removing or installing any coupling. Apply thread sealant tape (PTFE) to the male threads per standard practice before threading the connector into its port. Torque to hand-tight plus a firm wrench turn — do not overtighten steel fittings in aluminum or brass ports.
