I want to order a slip washer, but i cannot figure out which one. The site i am looking at has three Hayward washers to choose from but do not offer any dimensions or thread size. I have looked every where on my fitting and cannot find any part numbers.
There is spx1023z3, spx1025z3 or spx1025z3 opt 3720-80
The site i am looking at is called poolpartsonline.
Thank you in advance for any advice you can give me.
