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

Series 217 High-Flow, 72 MPa

  • High ratio working pressure vs. flow performance
  • Non-drip on connection and disconnection
  • Safety locking included
  • Compact design
  • One-hand operated
  • Flat-face design


Series 217 couplings and nipples offers a superior flow performance in relation to working pressure. The product has a flat-face design that keeps air inclusion and spillage down to a minimum, protecting both the hydraulic system and the environment from contamination. The flat-face feature also enables one-handed operation and easy maintenance. To prevent unintentional connection and disconnection during operation, a safety lock is standard on all couplings. The CEJN Series 217 ultra high-pressure hydraulic quick disconnect is particularly suitable for high flow hydraulic systems.
