Oatey No-Calk 4" Thermoplastic Roof Pipe Flashing features a one-piece construction that eliminates any possibility of the collar coming off, ensuring durability and reliability. This innovative design includes a patented positive double seal that s a leak- fit around the vent stack. Its black color seamlessly blends with modern roofing materials and excellent weather resistance. The No-Caulk collar provides ample room for pipe expansion and movement, adapting to pipe shifts while maintaining a secure, leakproof seal. Suitable for roof angles from flat to 45 degrees, this flashing will not warp or crack and requires caulking. It fits all types of pipes, including copper, cast-iron, plastic, aluminum, and galvanized, making installation easy by slipping over the vent stack and automatically adjusting to pipe size and roof angle. Resistant to rust and corrosion, it also prevents roof discoloration, ensuring long-lasting performance and a clean appearance. Model Number:
