Thermal Control Products, Non-Drip Couplings & Nipples

Series 777, DN19 Stainless steel

  • Stainless steel version with high resistance to corrosion
  • 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.


The series is also available in four other sizes: series 277, 477, 577 and 677. Please refer to series 767 for an all-brass version. For other sizes in brass, refer to series 267, 467, 567 and 667.
