Ultra High-Pressure Hydraulic Products, Couplings & Nipples

Series 116 Stainless Steel, 21,750 PSI (150 MPa)

  • Stainless steel
  • Compact design
  • Non-drip on disconnection
  • Connects with other series 116 products


A CEJN original design for use on traditional tools such as tensioners, wrenches, pullers, power packs and more in harsh and corrosive environments. It features extremely small outside dimensions, and non-drip functionality is a given feature. All exposed components are stainless steel, or even acid proof steel, to provide the longest possible service life and thus saving both the environment and money. To further extend service life of the entire hydraulic system, both coupling and nipple are provided with plastic dust caps. Aluminum dust caps can be ordered separately.
