I have some that holds up almost as good as the old AeroTrend blue stuff in 3/4", 5/8" and 1/2". Slightly less wall thickness but you don't have to soak it in hot water to get it to stretch over a pipe.
I prefer Teflon but the Aerotrend super blue was really good. Does anyone know who was their supplier ? It would be nice to get that product into the current parts sales sites
