Imperial GV1376 Galvanized Vent Pipe Collar Flashing 4 in

Product Description

The IMPERIAL GV1376 is a galvanized steel collar flashing designed to seal the joint between a single-wall vent pipe and a chimney or roof penetration, preventing water infiltration at that critical transition point. Constructed from galvanized steel for corrosion resistance, this flashing fits a 4-inch diameter single-wall vent pipe. It is a standard component in residential and light-commercial venting installations and is typically installed by HVAC technicians or plumbers during new construction or vent system service.

This collar flashing is intended for use with 4-inch single-wall vent pipe in residential and light-commercial applications. It is commonly installed where a vent pipe passes through a roof deck or wall penetration adjacent to a chimney chase. Proper sealing at this location is essential to prevent moisture intrusion that can cause structural damage, mold growth, and deterioration of nearby insulation or framing members.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Before installing, ensure the vent system is fully shut down and cooled. The flashing should be seated firmly against the roof deck or chimney surface and sealed with an appropriate high-temperature or roofing-grade sealant as required by local building codes. Follow applicable IFGC and local mechanical code requirements for vent pipe clearances and penetration sealing.
