Oatey Oatey-14137 14137 Rain Collar 3"-4" No-Calk Roof Flashing, Black

These worked out great for stopping water from getting in. The original units deteriorated along the rubber seal allowing water to get in. These worked out well without having to pull and shingles back. The only suggestion I have is to use some clear silicone calk on the underside. They say no caulk needed, however, it did not seat flush up against the original creating a watertight seal. Otherwise it sealed as expected around the PVC vent.

I have a 30 year old home. I'm going to need a new roof soon but the existing plumbing vents were rotting away from the PVC pipes. I put these over the existing and they went on easily. This should tide me over until I get the new roof

Doesn’t fit quite as tight as I was hoping, tho it probably does the job.

Easy to install. The tire has cracks and needed this tube. Now I can use the tire for a long time.

Easy install! Slid right onto the vent pipe to resolve a damaged flashing ring.

My old vent pipe on my roof was starting to leak and I did not want to call a roofing company to fix it. Installing this was very easy, no tools needed and I am confident I will not get anymore leaks.

Pretty easy to adjust the size by pulling with pliers.I think this should be a few dollars cheaper given the fact that it's just rubber.Would purchase again though.

Worked great and easy to install. Very product for a cracked vent boot repair.
