  • Durable and robust to tolerate long periods of connection
  • No-spill sealing suitable for cooling applications

 

The robust and reliable quick connect coupling series 777 with DN19 made of stainless steel is corrosion-free and adaptable to virtually all applications within the thermal management field. The non-drip design of the series ensures no spill and eliminates contamination and air inclusion into the cooling system. The one-hand-operated series is available in three versions: double shut-off, single shut-off and straight through. The coupling withstands over 10,000 connection cycles. Series 777 is available with colour-coding and/or key coding for extra safety. Optional sealing material is available upon request.
