Coilhose Pneumatics 1105 Pneumatic Hose Coupling

Product Description

The COILHOSE PNEUMATICS 1105 is a high-flow interchange pneumatic hose coupling connector designed for use in compressed-air distribution systems. Built from nickel-plated steel, this connector features a 3/8-inch FNPT threaded connection and a 1/4-inch body diameter. The high-flow interchange design allows increased air delivery compared to standard industrial interchange couplings, making it a practical choice for air tools, pneumatic equipment, and shop air lines. HVAC technicians, plumbers, and general trade professionals routinely use couplings of this type to connect pneumatic hoses to tools or fittings at air supply points.

This coupling is suited for residential and commercial shop environments where compressed-air tool lines require a reliable threaded connector. The 3/8-inch FNPT thread size fits standard pipe threads commonly found on air compressor outlets, manifolds, and inline fittings. The high-flow interchange format is compatible with other high-flow interchange series components, supporting efficient airflow to demanding pneumatic tools. It ships as a single-piece unit and is a direct fit for new installations or replacement of worn couplings in existing pneumatic systems.

Key Features

• High-flow interchange design for increased air delivery compared to standard industrial interchange couplings
• 1/4-inch body diameter with 3/8-inch FNPT threaded connection
• Nickel-plated steel construction for corrosion resistance in shop environments
• Threaded connection type for secure, leak-resistant installation
• Single-piece unit sold individually for targeted replacement or new installation

Compatibility

Designed as a high-flow interchange series connector compatible with other high-flow interchange pneumatic coupling components. Suitable for use with compressed-air systems using 3/8-inch FNPT threaded ports.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed-air system work. Always depressurize and isolate the air supply line before removing or installing couplings. Use thread sealant tape rated for pneumatic service on the FNPT threads to prevent air leaks. Do not overtighten threaded connections, as this can damage the female pipe threads on the mating fitting.
