Coilhose Pneumatics 123 Pneumatic Hose Coupler 1/2 in

Product Description

The COILHOSE PNEUMATICS 123 is a threaded pneumatic hose coupler designed for use in compressed air systems requiring a reliable, leak-resistant connection. Built from steel with a nickel-plated finish, this coupler features a 1/2 inch body diameter and a 3/8 inch female NPT (FNPT) thread. It handles a maximum working pressure of 300 psi and operates across a wide temperature range of -40 to 250 degrees F. The Industrial Interchange profile makes it a widely compatible choice for shop air lines, pneumatic tool connections, and general-purpose compressed air distribution. Licensed contractors and industrial maintenance technicians are the primary installers.

This coupler is suited for both light commercial and industrial pneumatic systems where the Industrial Interchange standard is specified. It is a threaded-connection coupler, making it appropriate for permanent or semi-permanent air line terminations on drops, manifolds, and tool connection points. The 1/2 inch body diameter supports adequate airflow for most pneumatic hand tools and small automation equipment. The nickel-plated steel construction offers corrosion resistance in typical shop environments.

Key Features

• 3/8 inch FNPT threaded connection for secure, leak-resistant installation
• 1/2 inch body diameter supports adequate airflow for pneumatic tools
• Rated to 300 psi maximum working pressure
• Operating temperature range: -40 to 250 degrees F
• Nickel-plated steel construction for durability and corrosion resistance

Compatibility

Designed as an OEM-style replacement or direct-install coupler for compressed air systems using the Industrial Interchange standard with 3/8 inch FNPT threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system safety practices. Depressurize and lock out the air supply before servicing any pneumatic line connection. Apply thread sealant tape or paste appropriate for compressed air service to the FNPT threads before tightening. Do not exceed the rated 300 psi working pressure.
