Coilhose Pneumatics 166 Pneumatic Hose Coupler Brass

Product Description

The COILHOSE PNEUMATICS 166 is a brass pneumatic hose coupler designed for compressed air systems using the Tru-Flate Automotive interchange standard. It features a 1/4 inch body diameter and a hose barb thread type sized for 3/8 inch inside diameter hose. Rated to 300 psi maximum working pressure and operable across a temperature range of -40 degrees F to 250 degrees F, this coupler is built for reliable service in shop and industrial pneumatic tool lines. It is typically installed by HVAC technicians, maintenance mechanics, or industrial service pros working with air-powered equipment.

This coupler fits compressed air tool setups where the Tru-Flate Automotive interchange style is the shop standard. The hose barb connection suits 3/8 inch ID pneumatic hose commonly used with impact wrenches, ratchets, blow guns, and other automotive and light industrial air tools. Its brass construction resists corrosion in typical shop environments. Sold individually, it is a straightforward one-for-one replacement or new-installation fitting for any Tru-Flate-compatible pneumatic circuit.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize the air line fully before disconnecting or installing any coupler fitting. Ensure the hose barb is fully seated and secured with the appropriate clamp before returning the line to service. Verify that the connected hose and downstream fittings are also rated for the system operating pressure.
