Cejn 10 550 5004 Pneumatic Hose Coupling 1/2 in

Product Description

The CEJN 10 550 5004 is a high-flow pneumatic hose coupling connector designed for industrial compressed-air systems. Built from steel with a zinc finish, this Series 550 connector features a 3/8-inch hose barb thread and a 1/2-inch body diameter, accepting hose with a 3/8-inch inside 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 year-round shop and field use. Licensed HVAC technicians, plumbers, and industrial mechanics install this type of fitting when assembling or repairing pneumatic tool lines and air supply systems.

The 10 550 5004 fits within the Industrial Interchange standard, allowing it to pair with Industrial Interchange-compatible couplers and bodies widely used across maintenance, manufacturing, and trade service environments. Its hose barb connection style is appropriate for flexible pneumatic hose assemblies where a secure, tool-free hose attachment is needed. This connector is sold individually and is well suited for both single-point repairs and larger pneumatic line builds in residential, commercial, and light industrial settings.

Installation Notes

Installation is typically performed by a qualified mechanic or technician. Depressurize and bleed the air line completely before disconnecting or installing any pneumatic fitting. Ensure the hose inside diameter matches the 3/8-inch barb before seating the hose, and secure with an appropriate clamp per the hose manufacturer's recommendation. Inspect the connection for leaks after pressurizing the system.
