OATEY THERMOPLASTIC NO-CALK ROOF FLASHING - 4" PIPE

Oatey No-Calk thermoplastic roof flashing forms a watertight seal around plumbing vent pipe and Type B gas vent penetrations on residential and commercial roofs. A rigid black thermoplastic base sets flat against the shingles or built-up underlayment while an integral self-sealing rubber collar slides down and locks against the pipe - no roof cement or caulking required at the pipe-to-flashing junction.

• Fits 4" pipe
• Base: 12" x 16"
• Material: rigid black thermoplastic base with flexible self-sealing rubber collar
• Self-sealing collar slides over the pipe and locks against it - no caulking required
