Oatey® invented the flashing industry more than 100 years ago. Today Oatey Flashings are used in commercial and residential applications where a water-tight seal around plumbing vent pipe or outside wall penetrations is required. Oatey Color Roof Flashings feature a color base that are available in brown, black or gray. Made of aluminum or galvanized materials, its self-sealing collar slides over pipe and requires no caulking.
