Series 267, DN4 Brass

- One-hand-operated coupling with non-drip design
- Durable and robust to withstand long periods of connection
- Different safety levels to avoid mixing media and incorrect flow direction
CEJN series 267 no-spill quick connect couplings are adaptable to virtually all thermal management applications and system requirements. Made of brass, this affordable DN4 coupling with non-drip design ensures zero spillage and eliminates pollution and air inclusion during connection and disconnection for long-term use and reliable liquid cooling. The quick disconnect is available in three configurations: double shut-off, single shut-off and straight through. Series 267 is also available with colour-coding and/or key coding for extra safety. Optional seal material is available upon request.
The series is also available in four other sizes: series 467, 567, 667 and 767. Please refer to series 277 for a stainless steel version. For other sizes in stainless steel, refer to series 477, 577, 677 and 777.
