DuraVent PolyPro EPDM Replacement Gasket: standard rubber seals for rigid pipe and fittings
The DuraVent PolyPro EPDM Replacement Gasket is a replacement for the standard rubber seal in rigid PolyPro pipe and fittings. It sits inside the female end, the wider opening that receives the next piece. Choose 2, 3, 4, 5, 6, or 8 inch to match your vent. Packs contain 12 gaskets for 2 through 4 inch sizes and 6 for 5 through 8 inch sizes. Use only soapy water for lubrication. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
The gray plastic resists corrosion from the acidic liquid in cool, wet exhaust and tolerates hotter exhaust than PVC or CPVC. Wall straps carry the vent’s weight, not the appliance. They support horizontal, sloped, and vertical sections, with a strap near each elbow or tee. A firestop, a barrier around the vent opening, goes at every floor and ceiling the vent crosses, including the attic floor but not the roof deck. Looking for the other gasket material? See the DuraVent PolyPro Viton Replacement Gasket. The DuraVent PolyPro EPDM Replacement Gasket ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
