Series 667, DN14 Brass

  • One-hand-operated coupling to simplify maintenance and serviceability
  • Safety lock to prevent unintentional disconnection
  • Precision-made no-spill flush-face connectors for liquid cooling

 

Thermal control requires safe, easy and reliable quick connect couplings. CEJN series 667 with DN14 are affordable non-drip modular couplings adaptable to virtually all applications and system requirements. The series ensures practically no spillage and eliminates pollution and air inclusion. Tests confirm that the Non-Drip series withstands over 10,000 connection cycles. Series 667 quick disconnects are available in double shut-off, single shut-off and straight through versions. Upon request they come in colour-coding and/or key coding for extra safety. Optional sealing material can be arranged.

 

The series is available in four other sizes: series 267, 467, 567 and 767. Please refer to series 677 for an all-stainless steel version. Additional sizes in stainless steel are series 277, 477, 577 and 777. If you can’t find a product that meets your requirements, don’t hesitate to contact us, and we’ll put our R&D department at your disposal. Applications: Data server chiller cooling lines, chassis manifolds, IGBTs, power converters, power inverters, rectifiers, industrial drives, power generators, heat exchangers, medical and industrial lasers, traction control, machine tools, solar power, alternative energy.
