Coilhose Pneumatics 1404 Pneumatic Coupling 1/8 in Mnpt Aro

Product Description

The COILHOSE PNEUMATICS 1404 is a pneumatic hose coupling connector designed for compressed-air systems in industrial, commercial, and trade service environments. Built from steel, this connector features a 1/8-inch MNPT threaded connection and a 1/8-inch body diameter. It follows the ARO interchange standard, making it compatible with ARO-style pneumatic systems and tooling. The threaded NPT connection provides a secure, leak-resistant fit when properly installed. Licensed HVAC technicians, plumbers, industrial maintenance techs, and pneumatic tool service professionals are the typical installers for this type of fitting.

This connector is suited for use in compressed-air distribution lines, pneumatic tool hookups, and air-line assemblies where ARO interchange fittings are specified. The 1/8-inch thread size makes it appropriate for smaller-diameter air lines and light-duty pneumatic circuits. It is commonly used in workshop, service truck, and facility maintenance applications where ARO-type quick-connect or threaded coupling systems are already in place.

Key Features

• ARO interchange standard for broad compatibility with ARO-style pneumatic systems
• 1/8-inch MNPT threaded connection for secure, NPT-standard fitment
• 1/8-inch body diameter for use in small-bore air lines
• Steel construction for durability in compressed-air service
• Threaded connection type for reliable, tool-assisted assembly

Compatibility

Designed as an ARO interchange-style connector for pneumatic air-line systems using 1/8-inch MNPT threaded fittings.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed-air systems. Depressurize and lock out the air supply before removing or installing any coupling or fitting. Apply thread sealant or PTFE tape to NPT threads per standard practice, and tighten with appropriate wrenches — do not overtighten steel fittings into soft or cast bodies. Verify all connections are leak-free before returning the system to service.
