Yes those are essentially the same thing I have now. They are too stiff under pressure contributing to the kink in the Mosmatic hoses.
Kleen Rite (Dave) told me to try model SWV38ss or SW0260. He thought the SWV38ss would work but in looking at it, I'm not certain. I really didn't want to spend $30 on the SW0260's. I might get by with the SW0260 at the gun and use what I have now which is the 7080 or 7044 JE Adams at the boom. As far as the corrosion, he sent me to Customer service and they sent my pic to Mosmatic. If they come back and blame the water, I am requesting for Mosmatic to let KR know just what is it they are looking for in the water report, so we'll see what they come back with. I may have to try a couple different swivels unless you have one you would prefer I try first. Thx
