Back in our dredging days
we used a product called tiger flex hose
Doesn't get cold a break like some, stays flexible, keep it out of the sun when not in use.
Outfit in Oregon, I believe called universal products, maybe, been a few days (years)
If you are using 4", I have a "T" handle hose clamp left over from our dredging days
that I will give you, you pay the freight.
