Parker EZ-371-6PL Push-lok Hose Barb Coupler 3/8 in Steel

Product Description

The PARKER EZ-371-6PL is a Push-Lok hose barb coupler designed for industrial pneumatic systems. Built from steel, it features a 3/8-inch body diameter and accepts 3/8-inch hose ID Push-Lok hose assemblies. The barb design locks hose in place without clamps, making it a reliable choice for compressed-air and pneumatic fluid-transfer lines. Licensed technicians and industrial maintenance professionals install this fitting in applications where a secure, tool-free hose connection is required. The steel construction provides durability under typical shop-air pressures and mechanical stress conditions.

This coupler fits 3/8-inch Push-Lok hose and is used in industrial pneumatic plumbing, compressed-air distribution, and general fluid-transfer setups. It is suited for both in-shop equipment and field pneumatic assemblies. The Push-Lok hose barb design eliminates the need for external clamps or crimp tooling, speeding up assembly and reducing hardware count. Maintenance technicians and industrial plumbers working on pneumatic tool lines, air-actuated equipment, and portable compressor systems commonly select this fitting for quick-connect hose terminations.

Installation Notes

Depressurize the pneumatic system fully before removing or installing any hose fittings. Push-Lok fittings are installed by hand — push the hose end firmly onto the barb until it seats; no clamps or tools are required for hose attachment. Verify that the hose ID matches the specified 3/8-inch barb before installation. Follow applicable industry and facility safety procedures when working on pressurized pneumatic lines.
