Imperial GV1379 Galvanized Vent Pipe Collar Flashing 8 in

Product Description

The IMPERIAL GV1379 is a galvanized collar flashing designed to seal the joint between a single wall vent pipe and the chimney or roof penetration point. Made from galvanized steel, this flashing prevents water intrusion at the collar, protecting the surrounding structure from moisture damage. The GV1379 fits an 8-inch diameter single wall vent pipe and ships as a single unit. Licensed HVAC technicians and chimney installers use this flashing during new vent installations or as a replacement when existing flashings become corroded or damaged.

This flashing is intended for use with 8-inch single wall vent pipe applications in residential and light commercial settings. It is commonly installed where a gas appliance vent, water heater flue, or similar single wall metal pipe passes through a roof deck or chimney chase. It is part of the IMPERIAL GV137x series, which covers 4-inch (GV1376), 6-inch (GV1378), and 8-inch (GV1379) pipe diameters, allowing installers to match the correct flashing to the installed pipe size.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified roofer as part of a venting or chimney service call. Shut off and allow the connected appliance to cool before working on or near the vent pipe. Verify the flashing diameter matches the installed pipe size before fastening. Follow local building codes and applicable provisions of the International Fuel Gas Code (IFGC) for venting system requirements.
