Cejn 10 430 5455 Pneumatic Coupling 1/2 in Mnpt

Product Description

The CEJN 10 430 5455 is a high-flow pneumatic hose coupling connector designed for industrial compressed-air systems. Built from zinc-finished steel, this Series 430 connector uses a 1/2-inch male NPT (MNPT) threaded connection and features a 3/8-inch body diameter. It is rated for a maximum working pressure of 232 psi and handles temperatures from -4 degrees F to 212 degrees F, making it suitable for demanding shop and production-floor environments. HVAC technicians, industrial maintenance crews, and pneumatic-tool operators install this type of fitting when building or servicing compressed-air distribution lines.

This coupling is intended for industrial interchange pneumatic systems operating on standard shop air supplies. The threaded MNPT connection allows direct installation into air hose assemblies, manifolds, or tool inlets without adapters. Its high-flow connector design reduces pressure drop across the coupling, which matters when running air-hungry tools or multiple drops from a single compressor. The zinc finish provides corrosion resistance in typical shop and light-industrial settings.

Key Features

• High-flow connector design minimizes pressure drop in pneumatic lines
• 1/2-inch MNPT threaded connection for direct installation into standard fittings
• 3/8-inch body diameter — industrial interchange compatible
• Maximum working pressure: 232 psi
• Operating temperature range: -4 degrees F to 212 degrees F
• Zinc-finished steel construction for durability and corrosion resistance

Compatibility

Designed as an industrial interchange-style pneumatic coupling connector compatible with standard industrial interchange pneumatic systems and tool inlets accepting a 1/2-inch MNPT threaded connection.

Installation Notes

Installation should be performed by a qualified technician or maintenance professional familiar with compressed-air systems. Always depressurize and bleed down the air line completely before disconnecting or installing any coupling. Apply thread sealant appropriate for pneumatic service to the MNPT threads before installation. Verify that the system operating pressure does not exceed the 232 psi maximum working pressure rating of this fitting.
