Use on Intex Chlorine Generator to connect to 1.25" hose.
This is for a 32mm or 1.25" hose (I originally posted as 31mm, my bad).
Why ANOTHER 32mm you ask?
This one sliced and printed much better for me, maybe due to the fact that the number of facets is less than the original.
TIP: Electrical tape works great if you don't have teflon tape on-hand.
