The key in making foam brush hose last a long time is having a low pressure swivel at the handle and a good bend restrictor. I make my own hose using a same 3/8 male fitting with a crimp machine like in high pressure hose. I than slide a 2 feet of 3/4 clear vinyl Kuriyama 1/8 thickness (bend restrictor) back over the fitting with help of a hot gun during the winter. During the summer, no need for hot gun just some WD40.
With time usually about a year out, the kuriyama tubing will crack at the 3/8 fitting end. I get a knife and cut 2inch off Kuriyama bend restrictor off and slide the remaining 22 inch reverse back on the 3/8 fitting. I keep doing this until the Kuriyama is too aged from sun damage. The blue hose should be reusable many times unless you make it too long and it rub on the concrete. Also don't wait too long to fix the crack in bend restriction or the blue hose will crack at the fitting end also.
As for the other end on the boom, I have a brass 3/8 barb. I don't recommend a clamp on it because the barb will cut the hose. Without the clamp it acts like a swivel. Every few months just cut 1 inch of blue hose off and push back in barb.
