Coilhose Pneumatics 1509 Pneumatic Hose Coupling Connector

Product Description

The COILHOSE PNEUMATICS 1509 is a pneumatic hose coupling connector designed for compressed air and pneumatic tool applications. Built to Industrial Interchange standards, this connector features a 1/8 inch FNPT threaded connection and a 1/4 inch body diameter. Constructed from nickel-plated steel, it delivers reliable, corrosion-resistant performance in shop and field environments. This style of coupling is used by HVAC technicians, plumbers, electricians, and general trade professionals who operate pneumatic tools powered by shop air compressors. The threaded design allows for straightforward installation into standard air line fittings and manifolds.

This coupling connector is suited for light industrial and commercial shop environments where Industrial Interchange pneumatic fittings are the standard. It threads into ports on air hose assemblies, quick-connect manifolds, and pneumatic tool inlets using a 1/8 inch FNPT connection. Typical applications include air-powered tool stations, compressor outlet connections, and in-line air distribution systems. Its compact 1/4 inch body diameter keeps it compatible with standard bench and portable compressor setups found across multiple trades.

Key Features

• Industrial Interchange coupling type for broad cross-brand compatibility with matching couplers and plugs
• 1/8 inch FNPT thread size for direct connection to standard air line ports and fittings
• 1/4 inch body diameter suits compact air tool and hose assembly configurations
• Nickel-plated steel construction resists corrosion and wear in shop environments
• Threaded connection type provides a secure, leak-resistant fit without additional tooling

Compatibility

Designed as an OEM-style connector compatible with Industrial Interchange pneumatic coupling systems using 1/8 inch FNPT threaded ports.

Installation Notes

Installation should be performed by a qualified technician with the compressed air system fully depressurized and locked out before service. Use appropriate thread sealant tape on FNPT threads to ensure a leak-free connection. Hand-tighten first, then snug with a wrench — avoid overtightening steel threaded fittings to prevent thread damage. Verify system pressure ratings are within the component specifications before returning the air supply to service.
