This flashing is part of the Selkirk MetalBest RV line, a round Type B gas vent system built for residential and light commercial and industrial applications. It accommodates roof pitches from 0 to 6 over 12, making it a practical fit for a wide range of rooflines without requiring a separate flashing for each slope. HVAC installers and service technicians rely on this type of roof flashing to create a weathertight seal around the vent penetration while maintaining proper clearance and alignment for the gas vent system. The 8 inch size refers to the inside diameter of the vent pipe or fitting. The outside diameter of RV pipe is approximately one half inch larger than the listed inside dimension. The outer shell is constructed from 28 gauge galvanized steel, which resists corrosion and holds up well against outdoor exposure including rain, temperature swings, and UV. The inner liner is aluminum, which is well suited for the byproducts of gas combustion and helps maintain the integrity of the venting path over time. Type B gas vent systems like the RV line are approved for use with natural gas and propane appliances including furnaces, boilers, water heaters, and unit heaters. Proper roof flashing is a critical component in any venting installation. It prevents water intrusion at the roof deck and keeps the vent pipe properly supported and sealed through the roofline. This adjustable design simplifies installation by eliminating the need to match a fixed-pitch flashing to the exact slope of the roof. HVAC contractors, sheet metal installers, and mechanical trades professionals working on residential or light commercial gas appliance venting projects will find this flashing a reliable and code-compliant choice for completing a Type B gas vent penetration through the roof.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdjustable pitch range of 0 to 6 over 12 fits a wide variety of roof slopes\u003c\/li\u003e\n\u003cli\u003e28 gauge galvanized steel outer shell provides durable weather and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eAluminum inner liner is compatible with Type B gas vent applications for natural gas and propane appliances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 108825 RV Adjustable Roof Flashing gives HVAC and mechanical installers a flexible, code-compatible solution for sealing 8 inch Type B gas vent penetrations through roofs with pitches from flat to 6 over 12.
