Coilhose Pneumatics 5804 Pneumatic Hose Coupling 3/8 in

Product Description

The COILHOSE PNEUMATICS 5804 is a threaded pneumatic hose coupling connector designed for compressed-air distribution lines in industrial and shop environments. Built from nickel-plated steel, this connector uses a 1/4-inch FNPT (female national pipe taper) thread and features a 3/8-inch body diameter. The Industrial Interchange design makes it compatible with the most widely used quick-connect coupler standard in North American shops and facilities. At 0.2 pounds, it is a compact, single-piece connector intended for permanent or semi-permanent installation on air lines, tools, and manifolds. Licensed trades and industrial maintenance techs will find the nickel-plated finish useful in environments with moderate corrosion exposure.

This coupling connector is suited for use in residential and commercial compressed-air systems, including production facilities, automotive service bays, general manufacturing, and contractor job sites. It threads directly into standard 1/4-inch FNPT female ports on air hoses, tools, regulators, and distribution manifolds. The Industrial Interchange profile is the most common quick-connect standard in the U.S. market, making the 5804 a practical stock item for shops that need to maintain consistent coupler compatibility across multiple tools and hose assemblies.

Key Features

• Industrial Interchange coupler type for broad compatibility with U.S. shop-standard quick-connect fittings
• 1/4-inch FNPT threaded connection for direct install into standard air-line ports
• 3/8-inch body diameter suits mid-range compressed-air flow requirements
• Nickel-plated steel construction for corrosion resistance and durability
• Compact and lightweight at 0.2 pounds for use in tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-install connector for compressed-air systems using the Industrial Interchange quick-connect coupler standard with 1/4-inch FNPT threaded ports.

Installation Notes

Installation is typically performed by industrial maintenance technicians, plumbers, or HVAC service pros working on compressed-air distribution systems. Always depressurize and bleed the air line completely before removing or installing any coupling or fitting. Apply thread sealant tape or pipe compound rated for compressed air to the FNPT threads before assembly. Hand-tighten first, then wrench-tighten to avoid cross-threading the steel fitting.
