I love replacing 90 degree swivels. My favorite is when a hose falls out of the 360 boom and you have to put it back in. (If you have ever replaced one before you know what I’m talking about.)
I thought that my 90 degree swivel was leaking but after I replaced it with my shiny new Mosmatic swivel. I noticed that the boom is leaking. It looks like if it was welded where the previous weld is maybe it would quit leaking?
