Ultra High-Pressure Hydraulic Products, Flat-Face Couplings & Nipples

Series 115 Flat-Face

CEJN Series 115 offers a Flat-Face design and a patented auto-lock function. The couplings are light in weight with an aluminum back part, making the series ideal for applications in which lightweight components are a requirement. Series 115 is recommended primarily for rescue equipment, torque tools and cable cutters. A standard version is also available.
