The CEJN 10 410 5452 is a high flow pneumatic connector designed for compressed air systems requiring efficient, high-volume airflow through a threaded fitting interface. Built from steel with a zinc finish, this Series 410 connector features a 3/8 inch body diameter and a 1/4 inch male NPT (MNPT) threaded connection. 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 industrial pneumatic service. Licensed tradespeople and pneumatic system technicians install this type of fitting in production, maintenance, and service environments.
This connector is used in high flow pneumatic tool and equipment circuits where standard interchange couplings restrict airflow. Typical applications include compressed air distribution lines, pneumatic tool connections, and service drop assemblies in commercial, industrial, and trade service settings. The 1/4 inch MNPT thread fits standard NPT-tapped ports and manifolds common in these systems.
Designed as an OEM-style high flow replacement connector for pneumatic systems using Series 410 high flow interchange couplings with 1/4 inch MNPT threaded connections.
Installation should be performed by a qualified pneumatic systems technician or licensed tradesperson. Depressurize and lock out the air supply before disconnecting or installing any pneumatic fitting. Apply thread sealant appropriate for compressed air service to the MNPT threads before installation. Do not exceed the rated working pressure of 232 psi for this fitting.
