Coilhose Pneumatics 5902 Pneumatic Connector 3/8 in

Product Description

The COILHOSE PNEUMATICS 5902 is a threaded pneumatic hose connector designed for use in compressed air systems requiring Tru-Flate Automotive interchange compatibility. Built from nickel-plated steel, it features a 3/8-inch female NPT (FNPT) thread and a 3/8-inch body diameter. This connector is a standard coupler-side fitting used to join air hose assemblies to tools, compressors, and pneumatic equipment. It is installed by HVAC technicians, pipefitters, automotive service techs, and general maintenance professionals wherever a reliable, leak-resistant threaded air connection is needed.

The 5902 fits residential, commercial, and light industrial compressed air applications. Its Tru-Flate Automotive interchange profile makes it a direct fit in shops and service environments already running Tru-Flate-style quick-connect systems. Typical install scenarios include connecting air hose to impact wrenches, air ratchets, blow guns, and other pneumatic hand tools. The threaded FNPT design allows direct installation into standard pipe-threaded ports and fittings.

Key Features

• Tru-Flate Automotive interchange profile for compatibility with widely used quick-connect systems
• 3/8-inch FNPT threaded connection for standard pipe-thread ports
• 3/8-inch body diameter — a common size for mid-range compressed air tools
• Nickel-plated steel construction for corrosion resistance and durability
• Connector-type coupler suitable for tool-side and hose-side assembly configurations

Compatibility

Designed as an OEM-style replacement or standard connector for compressed air systems using Tru-Flate Automotive interchange quick-connect fittings with 3/8-inch FNPT threaded ports.

Installation Notes

Install and service compressed air fittings only after depressurizing the air line and disconnecting the supply at the compressor. Apply thread sealant tape to FNPT threads per standard plumbing practice before tightening. Use an appropriately sized wrench — do not overtighten, as steel NPT threads can crack cast ports if torqued excessively. Refer to applicable shop-safety and compressed air codes when installing in commercial or industrial environments.
