Enlarge heater hose end from 5/8" to 3/4"?
Due to very limited space around my heater, I need to enlarge the 5/8" heater hoses to 3/4" on one end. There isn't enough space for an adapter fitting.
Is this possible, for instance by using heat?
Or is it possible to have a couple of 5/8" heater hoses custom made with a short area of 3/4" diameter in one end?
