Ultra High-Pressure Hydraulic Products, Couplings & Nipples

Series 115, 100 MPa

Series 115 is available in both standard and Flat-Face designs. The series is a CEJN original with extremely small outside dimensions. Like all couplings in CEJN’s High-Pressure range, non-drip connection and disconnection are standard. All exposed components are made of zinc-plated steel. The couplings are also available in a safety ring design featuring a locking sleeve that prevents accidental disconnection. Extending the service life of the entire hydraulic system, plastic dust caps are standard on both the couplings and nipples. Aluminum dust caps are also available upon request. The nipples are also available with a hose rupture valve. In the event of a ruptured hose, the nipple closes and prevents oil spills that could disrupt production and harm the environment.
