Coilhose Pneumatics 1403 Pneumatic Hose Coupling Aro

Product Description

The COILHOSE PNEUMATICS 1403 is a pneumatic hose coupling connector designed for use in compressed-air distribution systems. Constructed from nickel-plated steel, this connector features a 3/8 inch male NPT (MNPT) thread and a 1/4 inch body diameter. The ARO interchange design ensures broad compatibility across pneumatic tool setups and air supply lines commonly found in shop, industrial, and field service environments. Weighing 0.1 pounds, it is a compact, durable fitting suited for installation by HVAC technicians, pipefitters, machinists, and general mechanical trades working with pneumatic systems.

This coupling connector is intended for use in threaded pneumatic connections where ARO-style interchange couplings are the standard. Typical applications include connecting air hoses to compressors, pneumatic tools, and inline fittings in both light industrial and heavy shop environments. The MNPT thread type makes it straightforward to install into standard NPT-tapped ports without adapters. It ships individually and is well suited for single-point replacements or new pneumatic line installations.

Key Features

• ARO interchange type for wide cross-brand pneumatic coupling compatibility
• 3/8 inch MNPT thread for direct connection to standard NPT-tapped ports
• 1/4 inch body diameter rated for typical shop air line sizing
• Nickel-plated steel construction for corrosion resistance and durability
• Threaded connection type — no crimping or barb tools required
• Lightweight at 0.1 pounds, compact form factor for tight installation spaces

Compatibility

Designed as an ARO-interchange replacement connector compatible with pneumatic systems using 3/8 inch MNPT threaded ports and 1/4 inch body couplings. Suitable for use wherever ARO-style pneumatic couplings are specified.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed-air systems. Before servicing any pneumatic connection, depressurize the air line completely and verify the system is isolated from the compressor. Apply thread sealant tape to the MNPT threads per standard practice before torquing into the receiving port. Follow applicable shop safety procedures and local codes governing compressed-air system work.
