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

Series 115, High-Flow, 80 MPa

  • Flat-face design
  • Non-drip on connection and disconnection
  • Dust caps included as standard
  • One-hand operated
  • Automatic safety locking device


CEJN has expanded its High-Pressure quick connect coupling range with new High-Flow Series hydraulic couplings. The new CEJN Flat-Face couplings are small in size but mighty in performance, making them particularly suitable for hydraulic tools with high-flow requirements
