Coilhose Pneumatics 1204 Pneumatic Hose Coupling 1/2 in

Product Description

The COILHOSE PNEUMATICS 1204 is a female NPT (FNPT) threaded pneumatic hose coupling designed for use in compressed air systems where reliable, leak-free connections are required. Built from nickel-plated steel, it features a 1/2-inch body diameter and a 3/8-inch thread size, conforming to the Industrial Interchange standard — the most widely used coupling format in North American shops and facilities. This connector-style coupling is suited for use in demanding environments where durability and corrosion resistance are priorities. HVAC technicians, plumbers, and general contractors rely on Industrial Interchange fittings for their broad tool and hose compatibility.

This coupling is intended for use in residential and light commercial pneumatic systems, including air compressor lines, pneumatic tool setups, and shop air distribution networks. Its FNPT thread connection allows direct installation onto standard NPT-threaded ports, manifolds, and air hose assemblies. The Industrial Interchange design ensures interoperability with the broad range of Industrial-standard couplers and plugs commonly found across trades and service applications.

Key Features

• Industrial Interchange standard for broad cross-brand compatibility with plugs and tools
• FNPT thread connection for direct installation on standard NPT-threaded ports
• 3/8-inch thread size with 1/2-inch body diameter
• Nickel-plated steel construction for corrosion resistance and durability
• Connector (coupler) type configuration for straightforward inline use

Compatibility

Designed as an OEM-style replacement or upgrade fitting for compressed air systems using Industrial Interchange standard couplings with FNPT threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air systems. Depressurize the air line completely before removing or installing any coupling. Apply thread sealant tape or compound rated for pneumatic service to the FNPT threads to ensure a leak-free connection. Torque to fitting manufacturer standards and verify with a soap solution or leak detector before returning the system to service.
