Questions & Answers

Does this cap have a rubber seal on the inside circle where it slips over the pipe?
ByApr 27, 2022
1 Answer | 
Answer This Question

The item you sent is a Storm Collar (not a cap). This slides over the pipe & should stop just above the roof flashing. At that point you should use a silicone sealant to secure it to the pipe. The sealant with keep it attached to the pipe (so it floats as the pipe expands & contracts) and will keep rain out. It does not have a built in seal, you need to apply silicone sealant yourself when installing. Many people will put a ring of sealant on the pipe just above the flashing. They'll slide the Storm Collar down until it meets this sealant. At that point, they'll put another bead of sealant to ensure a good seal & barrier against rain.
