My house was built in 1955 and there is 1/2 O.D. tubing coming into the utility
room for the washer hook up. I need to change fittings (elbows) and can not find
anything that will fit over the 1/2 inch O.D. I have been looking in Lowes (Box
store). What should I be asking for or have they stopped making these items?

I find plenty of fittings to fit 1/2 inch copper pipe, but not tubing.

Thanks
