In the realm of venting solutions, DuraVent stands tall as the undisputed industry leader. We take immense pride in presenting the DuraVent PolyPro Viton Gaskets, a testament to our commitment to innovation, safety, and excellence. In an age where every component matters, these gaskets signify a pivotal stride towards enhancing your HVAC and hearth systems' performance.

At DuraVent, we recognize the importance of seamless venting in your everyday life. Our PolyPro Viton Gaskets are meticulously engineered to meet the highest industry standards, offering you a venting solution that not only excels in performance but also in ease of installation and durability. Gone are the days of compromising on quality or struggling with complex installations. With DuraVent, you are assured of a product that not only simplifies your life but also saves valuable time and resources.

These gaskets are specifically designed for use with PolyPro, an engineered alternative for condensing gas appliances. Unlike traditional PVC, which comes with its limitations, PolyPro boasts a higher operating temperature limit of 230°F/110°C. This means enhanced safety and performance, especially in demanding applications like water heaters, condensing boilers, and warm air furnaces. Plus, with DuraVent's cutting-edge condensation management system, you can bid farewell to worries about moisture-related issues.


  • Enhanced Safety: DuraVent PolyPro Viton Gaskets ensure secure and reliable venting, reducing the risk of accidents.
  • Time and Cost Savings: Easy installation means reduced labor costs, making it a cost-effective choice.
  • Extended Durability: With a higher temperature limit, these gaskets are built to last, even in challenging conditions.
  • Efficient Venting: The condensation management system ensures efficient venting, contributing to appliance longevity.
  • Industry Leader: Trust in DuraVent, the industry leader, for unparalleled quality and performance.

DuraVent PolyPro Viton Gaskets find their utility in a broad spectrum of applications.

Our commitment to safety is underscored by the fact that Intertek lists PolyPro to the ULC S636 standard in Canada as a Class IIA, IIB, and IIC vent system. This certification attests to the product's ability to handle exhaust temperatures of up to 230°F/110°C and a maximum positive pressure of 15 in-w.c.
