Thermal Control Products, Non-Drip Couplings & Nipples

Series 467, DN6 Brass

  • One-hand-operated coupling with compact dimensions
  • Precision-made, no-spill coupling for liquid cooling
  • Safety lock to prevent unintentional disconnection


With unlimited combination possibilities in color-coding and/or key coding for extra safety, series 467 with DN6 is adaptable to most applications within thermal management. The durable design of the connector withstands more than 10,000 connection cycles, while the spill-free design and dry-break function eliminates contamination and air inclusion. Connection/disconnection is possible under full working pressure. The series is available in three configurations: double shut-off, single shut-off and straight through. Other sealing materials are available upon request.


The series is available in four additional sizes: series 267, 567, 667 and 767. Please refer to series 477 for a stainless steel version. Other sizes in stainless steel are series 277, 577, 677 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: High-performance computing racks/switch blades, Chassis manifolds, cold plates, rack CDU manifolds, GPU manifolds, LED equipment, fuel cells, graphic cards, theater projectors, medical imaging equipment.
