The CEJN 10 300 2004 is a steel pneumatic safety coupler designed for compressed air and pneumatic tool connections in industrial and trade service environments. It features a hose barb thread type sized at 3/8 inches and a body diameter of 1/4 inch, making it a compact and reliable fitting for securing air lines. Built to an ARO interchange standard, it is compatible with a wide range of pneumatic quick-connect systems already in the field. The zinc finish provides basic corrosion resistance. Licensed HVAC technicians, mechanics, and industrial maintenance professionals install this type of coupler when servicing or assembling pneumatic tool supply lines.
This coupler is suited for light industrial, shop, and field service applications where ARO-pattern pneumatic fittings are the standard. It connects to hose with a 3/8-inch inside diameter and handles working pressures up to 232 psi. The rated temperature range of -4 degrees F to 212 degrees F covers most indoor and outdoor service environments. It is sold individually and is a direct replacement for worn or damaged ARO-interchange couplers on existing pneumatic lines.
Designed as an OEM-style replacement fitting for pneumatic systems using ARO-interchange safety couplers with hose barb connections and 3/8-inch inside diameter hose.
Depressurize and bleed the air line completely before removing or installing any pneumatic coupler. This coupler is typically installed by maintenance technicians or pneumatic tool service professionals using standard hand tools. Ensure the hose inside diameter matches the 3/8-inch barb before securing with an appropriate clamp. Verify that the system working pressure does not exceed the 232 psi rating of this fitting.
