Cejn 10 550 2004 Safety Coupler 1/2 in Industrial Interchange

Product Description

The CEJN 10 550 2004 is a safety-style pneumatic hose coupling designed for industrial compressed-air systems. It features a 1/2 inch body diameter and connects to hose with a 3/8 inch inside diameter via a hose barb thread type. Constructed from brass and steel, it is rated for a maximum working pressure of 232 psi. This coupler is the female half of a quick-disconnect pneumatic connection point and is installed by HVAC technicians, pipefitters, and industrial maintenance mechanics who work on compressed-air distribution lines and pneumatic tool circuits.

This coupling is suited for industrial interchange applications where a standard Industrial Interchange-pattern safety coupler is required. The safety coupler design holds pressure until the connection is fully engaged, reducing the risk of accidental disconnection and uncontrolled air release. It is appropriate for use on shop-air headers, portable compressor whip lines, and pneumatic tool drops in both light industrial and commercial service environments where 232 psi or lower working pressures are present.

Key Features

• Safety coupler design prevents accidental disconnection under pressure
• Industrial Interchange pattern for broad compatibility with standard pneumatic fittings
• 1/2 inch body diameter with 3/8 inch hose barb inside diameter
• Rated to 232 psi maximum working pressure
• Brass and steel construction for durability in shop and industrial environments
• Hose barb thread type for direct attachment to pneumatic hose without additional adapters

Compatibility

Designed as an OEM-style replacement safety coupler for industrial compressed-air systems using Industrial Interchange-pattern pneumatic quick-disconnect fittings with a 1/2 inch body and 3/8 inch ID hose barb connection.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with compressed-air system safety practices. Depressurize and lock out the air supply line before removing or installing any coupler. Secure the hose barb connection with an appropriate clamp rated for the system working pressure. Verify that all fittings and hose are rated for at least 232 psi before returning the system to service.
