4″- 7″ Hightemp Silicone Pipe Boot Gasket


This High-Temp silicone (not EDPM) pipe boot is used for sealing your stove pipe and roof for a perfect water-tight seal.  Fits our 3″ insulated pipe (5″ outer diameter) out of the box with no trimming.  Can be trimmed to fit larger pipes up to 7″ diameter as long as the hole in the roof does not exceed 10″ across in any direction. Works great for flat or pitched roofs, with a nonporous roofing material like metal (including standing seam or corrugated) or rubber roofs.  Not compatible with most shingle roofs.

These boots are custom made for us in gray for aesthetic reasons. Any silicone pipe boot you can source in North America is orange, but there’s no physical reason why they need to be orange.  You can source black or gray EDPM boots but they don’t have the same temp ratings as silicone.

Availability: In stock
