Pneumatic Quick Couplings

The 140 Series is an original CEJN quick connect coupling designed for hydraulic applications with working pressures up to 400 MPa. Recommended for bearing pullers, dividers, bolt tensioning applications, hydraulic test installations, and extreme mining applications.
The 141 series mini-couplings are the smallest model of couplings on the market. The series offers the features of all CEJN products in a compact design and is suitable for fluid and vacuum applications as well as pneumatic applications.

The 135 series has been designed by CEJN for very high working pressures. In the disconnected position, the couplings and nipples can withstand a pressure of up to 300 MPa. The total absence of leaks during connection and disconnection is a general characteristic throughout the high pressure range.
