Cejn 10 340 3452 Pneumatic Coupler 1/4 Inch Mnpt Ss

Product Description

The CEJN 10 340 3452 is a stainless steel pneumatic hose coupler designed for industrial compressed air and pneumatic tool systems. Built to the industrial interchange standard, it accepts a 1/4 inch MNPT threaded connection and features a 1/4 inch body diameter. The stainless steel construction handles a maximum working pressure of 507 psi and an operating temperature range of -22 degrees F to 212 degrees F, making it suited for demanding shop floor, manufacturing, and industrial maintenance environments. Licensed HVAC and mechanical contractors, maintenance technicians, and industrial service professionals install this type of fitting as part of pneumatic distribution systems.

This coupler fits pneumatic hose assemblies requiring an industrial interchange-style quick-connect in a 1/4 inch MNPT configuration. It is typically used in industrial facilities, maintenance shops, and production environments where compressed air lines connect to tools, actuators, or other pneumatic equipment. The stainless steel body makes it a practical choice in areas with exposure to moisture, mild chemicals, or elevated hygiene requirements. Sold individually as a single unit.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize the air line completely before removing or installing any pneumatic fitting. Apply thread sealant appropriate for compressed air service to the MNPT threads per the fitting manufacturer and applicable facility standards. Inspect the mating plug for wear or damage before connecting to ensure a leak-free seal.
