When your backpack sprayer starts losing pressure or won’t hold prime like it should, you don’t need a whole new sprayer—you just need fresh seals. Nothing’s more frustrating than heading out to spray weeds only to find your pump isn’t pumping right. This repair kit gets your AgSmart sprayer back to full pressure so you can finish what you started.
What You’re Getting
- Complete set of O-rings and seals specifically sized for your pump
- Chemical-resistant materials that stand up to herbicides and pesticides
- Everything needed to rebuild the pump and stop those annoying leaks
- Much cheaper than buying a new sprayer when this one just needs fresh seals
Built for Real Farm Work
This repair kit works with the AgSmart 5-gallon backpack sprayer that comes with piston pump operation. Whether you’re spot-spraying thistles in the pasture, hitting weeds around fence lines, or treating brush along field edges, these seals keep your sprayer working when you need it most.
Made to Last
Pump seals take a beating from the chemicals you’re spraying and the constant pressure cycling. These aren’t generic hardware store O-rings—they’re made from materials designed to handle agricultural chemicals without swelling, cracking, or losing their seal over time.
Good to Know
Most pump problems come down to worn seals, so this kit solves the vast majority of backpack sprayer issues. Take your time during the rebuild, clean all the surfaces well, and lube the new seals with a compatible fluid before assembly. A little patience during installation saves you from doing the job twice.
