Cejn 10 300 5454 Pneumatic Hose Coupling Aro

Product Description

The CEJN 10 300 5454 is a high flow pneumatic hose coupling connector designed for compressed air and pneumatic tool applications. Built to ARO interchange standards, this threaded connector fits into existing ARO-compatible pneumatic systems without modification. The body diameter measures 1/4 inch with a 3/8 inch MNPT thread for a secure, leak-resistant connection. Constructed from zinc-finished steel, the 10 300 5454 handles a maximum working pressure of 232 psi and operates across a temperature range of -4 degrees F to 212 degrees F. It is sized and rated for demanding shop floor and industrial pneumatic service where high flow capacity matters.

This coupling connector is suited for use in residential, commercial, and light industrial pneumatic systems. Typical applications include air compressor outlet lines, pneumatic hand tools, blow guns, and shop air distribution networks that use ARO-style quick-connect fittings. Technicians, maintenance mechanics, and service pros working with ARO-interchange pneumatic systems will find this connector a direct-fit replacement or new installation component. The 3/8 inch NPT male thread is a common size across a wide range of pneumatic tool and equipment connections.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with pneumatic system service. Depressurize and lock out the air supply before connecting or disconnecting any pneumatic fitting. Apply thread sealant or PTFE tape to the MNPT threads in accordance with standard shop practice before threading into the mating port. Tighten to snug using an appropriate wrench — do not overtighten steel threaded fittings into softer port materials.
