Cejn 10 550 5405 Pneumatic Coupling 1/2 in Fnpt Steel

Product Description

The CEJN 10 550 5405 is a high flow pneumatic hose coupling designed for compressed air and pneumatic tool applications in industrial environments. Built from zinc-finished steel, this connector features a 1/2-inch female NPT threaded connection and a 1/2-inch body diameter. It is rated for a maximum working pressure of 232 psi and operates across a temperature range of -4 degrees F to 212 degrees F, making it suitable for demanding shop floor and industrial service conditions. The Series 550 design follows the Industrial Interchange standard, ensuring broad compatibility with common pneumatic quick-connect systems. Installation is handled by maintenance technicians and industrial mechanics.

This coupling is suited for use in industrial facilities, manufacturing plants, and maintenance operations where pneumatic tools and equipment are connected to compressed air lines. The Industrial Interchange design makes it a practical choice for shops running standard pneumatic quick-connect infrastructure. It is commonly installed at air distribution drops, tool stations, and compressor outlets where a threaded female NPT port is required for a secure, leak-resistant connection.

Key Features

• Industrial Interchange coupling type for wide system compatibility
• 1/2-inch female NPT threaded connection for secure, standard fitment
• 232 psi maximum working pressure rating
• Operating temperature range from -4 degrees F to 212 degrees F
• Steel construction with zinc finish for corrosion resistance in shop environments
• Series 550 high flow design supports efficient air delivery

Compatibility

Designed for use with Industrial Interchange pneumatic quick-connect systems using a 1/2-inch female NPT threaded port. Compatible with standard compressed air lines and pneumatic tool connections following the Industrial Interchange standard.

Installation Notes

Installation is performed by qualified maintenance technicians or industrial mechanics. Depressurize the air line completely before connecting or disconnecting the coupling. Apply thread sealant tape to the male NPT threads per standard practice, and tighten to hand-snug before using a wrench for final seating. Verify the line pressure does not exceed the 232 psi rated maximum before returning the system to service.
