Seal roof pipe penetrations without caulking using the Oatey No-Calk aluminum roof flashing. The self-sealing rubber collar slides down over the vent pipe for a watertight fit, and the rustproof stamped aluminum base shapes easily to match the roof profile.

• Fits 3" copper, cast iron, or PVC vent pipe
• 11" x 14-1/2" stamped aluminum base
• Rustproof .032" thick aluminum - hand-formable to roof profile
• Self-sealing rubber collar - no caulk required at the pipe
• Rated 180 deg. F continuous heat exposure - Type B vent approved
• Base accommodates roof pitch 0-40 deg. (up to 10/12 slope)
• Not for hot-mopped or built-up roofs

Tip: 3" is the most common main soil/vent stack size in modern residential plumbing. If the rubber collar stands taller than the pipe, trim it down with a utility knife at the next lower molded ring for a cleaner profile against the shingles.

Note: Do not apply petroleum-based caulk, sealant, or paint products to the flashing - they degrade the rubber collar and the aluminum's protective oxide layer.
