    • Its got all the right parts now
Turned out to be the wrong kit but my old Roundup sprayer apparently no longer has parts made for it. I bought a new unit and this kit contains all of the spare parts for the updated sprayers with the internal pump mechanism. So it turned out to be a good purchase after all!

    • Roundup No Leak Backpack Sprayer Service Kit
I have a Field King 4 gallon sprayer that needed some new seals and gaskets. This same kit was just $8 from the manufacturer but they wanted $$23 for S/H. After looking and not finding the OWM kit, I read this one may fit. This kit fit my sprayer perfect! It's a bit difficult to get a few parts apart to replace, but after reinstalling everything, this is great - a fraction of the price! Make sure to use a small amount of Vaseline on the parts before installing them. It makes them go together easier plus extends the life. ... show more

    • This actually worked to fix my 10 year old backpack sprayer.
Now it is not EASY to do the replacement job of the bottle of the tank seal - because you have to do it ONE HANDED reaching way down into the unit. But it is possible ... and the finished job works nicely and saved me money and saved the environment of another bunch of discarded plastic.
