Ultra High-Pressure Hydraulic Products, Couplings & Nipples

Series 116, 150 MPa

A CEJN original, Series 116 is offered in both standard and Flat-Face designs for use on cylinders, bolt tensioner tools, bearing pullers and more. It features extremely small outside dimensions, and non-drip connection and disconnection are standard. All exposed components are made of zinc-plated steel. The series includes a safety ring design featuring a locking sleeve that prevents accidental disconnection. The couplings and nipples are available in stainless steel and chemically nickel-plated steel for use in corrosive environments. The series also includes a coupling with a 90° angled swivel connection for use in confined areas. Extending the service life of the entire hydraulic system, plastic dust caps are standard on both the couplings and nipples. Aluminum dust caps can be ordered separately.
