To small for the elbow
These are too small to encompass the pipe/ elbow and adhere to itself. I'll order 1" next year and think it will fit the 3/4" ell. Or, continue to make my own. This was an oversight on the manufactures part to make this for a 3/4" ell and not test it to know it wouldn't fit. I'll order the 1" next winter and I think that'll fit the standard 3/4" galvanized elbow. It's possible these were designed for copper pipes bc they don't fit galvanized. I do however love their tee covers. They fit perfectly and close completely adhering to the opposite side and seal tightly.
