Series 567, DN9 Brass

  • Compact design and one-hand-operated quick connect coupling
  • Unlimited combination possibilities
  • A drip-free and flat-face fluid connector

Quick disconnect series 567 Non-Drip couplings are suitable for liquid cooling applications. The dry-break design of the series ensures practically zero spillage and eliminates pollution and air inclusion during connection and disconnection. This affordable DN 9 brass version is available in three configurations: double shut-off, single shut-off and straight through. Series 567 quick connect couplings are also available with colour-coding and/or key coding for extra safety. Optional sealing material is available upon request.

The series is available in four other sizes: series 267, 467, 667 and 767. Please refer to series 577 for a stainless steel version.
