Oatey® invented the flashing industry nearly 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 Rain Collars act as a protective water shield that slides over the existing flashing and prevents water damage. It can be used as a secondary seal for commercial and residential applications that require a watertight seal for roof penetrations around the plumbing vent pipe.
