Cejn 10 430 5452 Pneumatic Coupling 1/4 in Mnpt

Product Description

The CEJN 10 430 5452 is a high flow pneumatic hose coupling connector designed for compressed air and pneumatic tool systems. Built to the Industrial Interchange standard, this threaded connector features a 1/4 inch MNPT thread and a 3/8 inch body diameter. The steel construction with a zinc finish gives it solid corrosion resistance for shop and field environments. It is rated for a maximum working pressure of 232 psi and a temperature range of -4 degrees F to 212 degrees F, making it suitable for demanding pneumatic service. HVAC technicians, industrial maintenance mechanics, and plumbing contractors commonly use this type of fitting when connecting pneumatic tools and hose assemblies.

This connector is suited for use in residential and commercial pneumatic systems where Industrial Interchange couplings are the shop standard. It installs inline between a hose and a tool, compressor outlet, or manifold port using a standard 1/4 inch MNPT threaded connection. The Series 430 high flow design reduces pressure drop at the coupling point, which benefits air tools that require consistent volume delivery. Typical applications include air compressor hose connections, pneumatic control lines, and compressed air distribution in service vehicles and shop environments.

Key Features

• Industrial Interchange coupling type for broad tool and hose compatibility
• 1/4 inch MNPT threaded connection for standard pneumatic fittings
• 3/8 inch body diameter high flow design reduces pressure restriction
• 232 psi maximum working pressure for demanding compressed air service
• Steel body with zinc finish for durability and corrosion resistance
• Wide operating temperature range: -4 degrees F to 212 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit connector for pneumatic hose assemblies using the Industrial Interchange standard with 1/4 inch MNPT threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize the air line completely before removing or installing any coupling. Apply thread sealant appropriate for pneumatic service to the MNPT threads before tightening. Do not exceed the rated working pressure of 232 psi during operation.
