Quick-Connect Coupling for Nitrogen Tire Inflation

The SPEEDAIRE 30E653 is a 1/4 inch body-size socket designed for nitrogen tire inflation equipment. Its sleeve locking mechanism enables tool-free connection and disconnection. The anodized aluminum construction with a silver finish provides durability, while a poppet valve regulates airflow through the 1/4 inch NPT female thread.

Suits Workshops Using ARO Interchange Standard

This coupling fits technicians who need fast, secure hookups on nitrogen inflation systems compatible with the ARO interchange standard. The nitrile seals and operating range of -40°F to 150°F cover typical shop environments. Buyers requiring a different interchange profile or a plug-style component should look at alternative fittings.

High-Flow Capacity With Temperature Headroom

A maximum flow rate of 991.09 liters per minute handles demanding inflation tasks without restriction. The wide temperature span gives headroom for cold outdoor bays and hot compressor rooms. The poppet valve closes automatically on disconnect, preventing pressure loss when the coupling is not engaged.

Questions about this item

What thread size must the nitrogen inflation hose have to screw into the 1/4 in NPT female fitting?

The hose needs a 1/4 in NPT male thread to mate with the female port on this coupling.

Will the ARO interchange standard let this socket work with my existing ARO-style plugs?

Yes, the coupling follows the ARO interchange standard so it will accept compatible ARO plugs you already use.

How can I confirm the poppet valve is sealing properly after installation?

Pressurize the line and check for air leaks at the connection; a sealed poppet will hold pressure without audible loss.
