Parker H4F Pneumatic Hose Coupling 1/2 in Tru-flate 300 Psi

Product Description

The PARKER H4F is a steel pneumatic hose coupling connector designed for compressed air lines using the Tru-Flate Automotive interchange standard. It features a 1/2 inch body diameter and a hose barb thread type sized for 3/8 inch inside diameter hose. Rated to 300 psi maximum working pressure, this connector is built for reliable service in shop air systems, pneumatic tool circuits, and similar industrial or automotive air distribution applications. The zinc chromate finish provides corrosion resistance in typical service environments. Overall length is 2.53 inches and the unit weighs approximately 0.11 pounds.

This coupling connector is suited for use in automotive service shops, light industrial facilities, and commercial air supply setups where the Tru-Flate Automotive interchange standard is the established system. It connects to 3/8 inch ID air hose via the hose barb end and mates with standard Tru-Flate compatible plugs and sockets. Installation is typically performed by maintenance technicians, pneumatic system mechanics, or experienced shop personnel working with compressed air distribution lines.

Compatibility

Designed as an OEM-style replacement or new-installation connector for compressed air systems using the Tru-Flate Automotive interchange standard with 3/8 inch ID hose.

Installation Notes

Depressurize the air line completely before removing or installing any coupling components. Hose barb connections should be secured with an appropriately sized hose clamp rated for the working pressure of the system. Verify that the mating plug or socket is also Tru-Flate Automotive interchange compatible before assembly. Follow applicable workplace safety and compressed air system codes during installation and testing.
