PolyPro Applications

PolyPro is a polypropylene vent pipe for use with ANSI Category II and IV gas-burning appliances, including high-efficiency water heaters, condensing boilers, and warm air furnaces. PolyPro is an environmentally safe and engineered alternative for condensing gas appliances. Engineered for venting, it is 100% recyclable and contains no toxic or carcinogenic materials, chlorides, or heavy metals. PolyPro does not release hazardous gases during combustion, and has been used safely throughout Europe for over 20 years. PolyPro is engineered with a corrosion-free condensation management system, and is suitable for exhaust temperatures up to 230°F/110°C and a maximum positive pressure of 15 in-w.c.

The PolyPro Commercial Difference

Available in 5in. (130mm), 6in. (150mm) and 8in. (200mm) diameters.

Completely smooth inner wall for optimal flow performance.

Components designed for complete discharge of condensate.

Design allows for system distance adjustment from the back of the appliance.

PolyPro Testing


Wind Tunnel Laboratory

The wind tunnel lab allows us to gather precise data with 270° of measurement on terminations. All data is analyzed for product performance under rigorous conditions before going to market.


Rain Testing

Labs test the vapor/moisture barrier of products by subjecting them to extreme rain and wind conditions.These tests are compliant with both the US and Canadian requirements as well as the stringent European standards.


Climate Testing

Labs have developed a patented ice testing system in the climate room. Tests run to -4°F (-20°C). PolyPro vertical terminations are engineered to remain icicle free.

Commercial and OEM Product Development

DuraVent engineers are expertly skilled to develop venting components to OEM specs. To satisfy specific venting requirements, DuraVent has the experience to provide custom design, prototyping and testing of vent systems and components engineered to the demands of specific appliances.
