FWIW I prefer Adams 7080 swivel at the gun. It's the same swivel as the first one 2Biz linked but in brass. It's rebuildable but I've found that once it's worn to leaking they won't hold a kit anymore. They're cheap enough that I just change them when I change the hose.
Curious? Why would you use Brass when SS is available for the same price? You can rebuild the SS swivels for $2.15 including the backup rings...A lot less if you source the parts from somewhere else....I may have had 2 of these go bad in 6 years to where I had to rebuild them...Who knows how old the rest are!
I don't think you really need to use a high priced ball bearing swivel on the foam brush handle. We hang our foam brush handles horizontal and then 90 the hose down so it's vertical with a swivel on the 90, this takes a lot of the strain off the hose.Randy -
Would it be better to go ball bearing on HP and FB hose as well? Would rather pay the bigger amount up front...
