Cejn 10 300 5004 Pneumatic Hose Coupling Aro

Product Description

The CEJN 10 300 5004 is a steel pneumatic hose coupling connector designed for compressed-air and pneumatic tool lines. It features a hose barb thread type with a 3/8-inch thread size and a 1/4-inch body diameter, making it a compact connector suited to light-duty pneumatic distribution systems. The zinc finish provides corrosion resistance in typical shop and industrial environments. Rated to 232 psi maximum working pressure, this coupling handles the demands of standard pneumatic tool and equipment applications. Licensed HVAC techs, plumbers, and general tradespeople who maintain pneumatic supply lines will find this connector a direct-fit solution for hose barb terminations.

This connector is intended for use in pneumatic hose assemblies requiring ARO interchange compatibility. It accepts a 3/8-inch inside diameter hose and is suited for residential and light commercial compressed-air systems, pneumatic tool drops, and similar low-to-medium pressure air distribution setups. The ARO interchange format means it integrates with widely deployed quick-connect infrastructure found in service shops and mechanical rooms.

Key Features

• ARO interchange type for broad compatibility with existing pneumatic quick-connect systems
• 232 psi maximum working pressure rating
• Hose barb thread with 3/8-inch thread size and 3/8-inch hose inside diameter
• 1/4-inch body diameter for compact inline installation
• Zinc-finished steel construction for durability and corrosion resistance
• Operating temperature range: -4 degrees F to 212 degrees F

Compatibility

Designed as an ARO-interchange replacement connector for pneumatic hose assemblies using 3/8-inch inside diameter hose with hose barb connections.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize the air supply line completely before removing or installing any coupling. Ensure the hose barb is fully seated and the hose is secured with an appropriate clamp to prevent blowoff under pressure. Verify the system operating pressure does not exceed the 232 psi rated maximum of this coupling.
