Coilhose 1401 ARO Connector, 1/4 In. MPT

Description

Coilhose 1401 connector is a 1/4 inch ARO interchange pneumatic connector with 1/4 inch male pipe thread for shop air lines, hoses, and tool hookups. The plated steel connector gives maintenance teams a harder sealing surface for repeated coupling cycles in compressed-air service.

Coilhose 1401 connector Applications

• Air-tool hoses that use 1/4 inch ARO interchange couplers.
• Replacement plugs for shop benches, fabrication cells, and service carts.
• Threaded tool or hose ends that need a 1/4 inch MPT connector.
• Pneumatic accessory kits organized by interchange type.
• Repairs where damaged connectors cause leaks or poor seating.

Match this connector to an ARO interchange coupler before installation. Coupler families are not universal, and a near-match can connect poorly or leak under pressure. Keep ARO fittings separated from industrial, automotive, and Lincoln interchange parts so the correct connector is easy to find during a repair.

Coilhose 1401 connector Setup Notes

Clean the female thread on the tool, hose end, or adapter before adding the connector. Apply thread sealant approved for compressed-air systems, then tighten the connector without distorting the mating component. Pressurize the line and check the connection before returning the tool to daily work.

Because connectors take repeated impacts at the bench, inspect the nose and sealing surface when air loss starts or when a tool disconnects roughly. Replacing a worn plug can restore the connection without changing the hose or coupler.

This connector fits the plug side of the air connection, so it is often installed on tools, adapters, or hoses that move between stations. If a tool is used in several departments, confirm each station uses the same ARO standard before sending the tool out. Mixed standards slow repairs and can leave a crew chasing an air leak that is really an interchange mismatch.

Keep spare connectors near couplers, thread sealant, and hose repair parts. When a connector is replaced, check the coupler sleeve for dirt or wear and inspect the hose for cracking near the fitting. A clean pair of matching parts helps air tools connect quickly and hold pressure during repeated use.
