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 1-1/2" copper, cast iron, or PVC vent pipe
• 9" x 12-1/2" 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: 1-1/2" flashing fits the smaller vent stacks used for kitchen sinks, lavatory branches, and secondary plumbing vents. Position the base under the upper shingle course and over the lower course so water sheds across the base, never under it.

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.
