Oatey® invented the flashing 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. Flashings are available in a variety of thermoplastic, aluminum, galvanized and copper materials. All Oatey Flashings are rated for a minimum of 180°F continuous heat and approved for Type B Installations. Oatey also offers the Master Flash® for commercial applications, along with a variety of specialty items including Rain Collars and Mushroom Caps.
