Series 677, DN14 Stainless steel
- Precision-made dry-break coupling suitable for liquid cooling
- Safety lock feature to prevent unintentional disconnection
- One-hand-operated connector with compact dimensions
This robust stainless steel quick connect coupling series 677 is adaptable to virtually all thermal control applications. The colour-coding feature helps to separate incoming cool lines from outgoing hot lines. The non-drip design ensures zero spillage and eliminates pollution and air inclusion during connection and disconnection for long-term use. This stainless steel disconnect series with DN14 is available in three configurations: double shut-off, single shut-off and straight through. In addition, 677 can be delivered with colour-coding and/or key coding for extra safety. Optional seal material is available upon request.
The series is available in four other sizes: series 277, 477, 577 and 777. Please refer to series 667 for an all-brass version. For other sizes in brass, refer to series 267, 467, 567 and 767.
