Invaluable time saver!!

On 90 degree bends in tight areas these are BIG TIME& AGGRAVATION savers! Good material density/strength yet workable.As for adhesiveness just remember to work clean No Dirt,Oil etc. 5* Amazon Delivered!!

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.
