    Stainless seat - should last longer
  

*by B***R on Reviewed in the United States on May 22, 2022*

My original regulator, same mfg. but brass seat, was worn and due to bypassing, gunjet sprayer for trees was was getting weak. I had no clue, as I bought the sprayer used and obviously already worn out. This fixed it!
