Round Butterfly Vent Gasket, with pre-drilled holes
Made to perfectly fit our round aluminum butterfly vent. Closed cell foam means the gasket won't absorb water, and the vent won’t leak when shut. Works best if silicone is used on both sides of the gasket. Much neater than using weather-stripping or caulk.
Gasket is 1/16" thick, 1" wide material, 6" ID, 7 3/4" OD.We recommend using the vent & gasket together for vents installed on exterior walls of trailers.
