TruDesign Vented Loops

TruDesign Vented Loops are the superior composite siphon break solutions for marine applications. Vented Loops prevent water siphoning from underwater skin fittings back into a vessel, thereby guarding against accidental flooding and sinking. Vented loops are used predominantly in toilet to overboard applications, toilet inlet applications, and holding tank to overboard applications. They can also be used in genset or small engine inlet cooling water systems. The duckbill one-way valve is designed to seal even when particles are present in the fluid.


  • Silicone duck bill valve – Long life with no perishing or hardening
  • Constant internal diameter – No reduction in flow
  • Self-contained mounting – 3 screw mounting posts give secure and easy installation
  • Chemical resistant – Impervious to waste water and common toilet cleaning products
  • UV resistant – These fittings will not break down with ultraviolet light or discolour from the sun
  • High quality surface finish – Will not discolour with green film as similar bronze fittings do
  • Large operating temperature range – Suitable for all marine environments, from -40°C to +110°C
