Coilhose Pneumatics 5901 Pneumatic Hose Connector 3/8 Npt

Product Description

The COILHOSE PNEUMATICS 5901 is a male NPT pneumatic hose connector designed for use with Tru-Flate automotive interchange-style couplings. Built from nickel-plated steel, this connector offers corrosion resistance and reliable sealing in compressed-air service. The 3/8-inch body diameter and 3/8-inch MNPT thread make it a direct-thread fitting for standard air lines found in automotive shops, service bays, and light industrial environments. Licensed HVAC techs, auto service technicians, and general mechanics install this type of connector when building or repairing pneumatic tool circuits. The nickel finish extends service life in environments where moisture and oil mist are present.

The 5901 connector is suited for residential garages and commercial automotive service facilities running Tru-Flate-compatible quick-disconnect systems. It mates with Tru-Flate automotive interchange couplers on air compressor outlets, drop lines, and tool whips. The 3/8-inch NPT thread is the most common size in light- to medium-duty compressed-air distribution, making this fitting a routine replacement or add-on component when extending or reconfiguring an existing air line layout.

Key Features

• Tru-Flate automotive interchange type — mates with widely used quick-disconnect coupler systems
• 3/8-inch MNPT thread for direct connection to standard NPT-threaded air line ports
• 3/8-inch body diameter consistent with typical 3/8-inch air hose assemblies
• Nickel-plated steel construction resists corrosion in oily and humid shop environments
• Threaded connection type for secure, leak-resistant assembly

Compatibility

Designed for use with Tru-Flate automotive interchange-style couplers in standard 3/8-inch NPT compressed-air systems.

Installation Notes

Installation is performed by mechanics, HVAC technicians, or any trade working with compressed-air systems. Always depressurize and bleed the air line before removing or installing fittings. Apply thread sealant tape or paste rated for pneumatic service to the MNPT threads before assembly — do not overtighten, as this can crack the fitting body or distort the thread. Follow all applicable shop safety practices and local codes governing compressed-air systems.
