Description

Nothing takes the wind out of your spray day like a pump that’s leaking pressure through worn seals. You’re burning through more fuel, losing chemical concentrate, and watching your coverage slip while you fight with equipment that should be making your job easier. This O-ring kit gets your AR pump sealing tight again so you can get back to productive spraying.

What You’re Getting

Complete set of precision-sized O-rings engineered specifically for AR pump applications
Chemical-resistant rubber compounds that stand up to herbicides, insecticides, and fertilizer solutions
Exact replacement seals that restore factory performance and pressure ratings
Quality materials that handle the pressure cycles and temperature swings of field spraying

Built for Real Farm Work

AR pumps power everything from three-point sprayers to self-propelled applicators, and they take a beating during spray season. Whether you’re applying pre-emergent in cool spring weather or post-emergent under summer heat, these seals are designed to keep your pump delivering consistent pressure and flow rates when every pass counts.

Made to Last

Farm chemicals are tough on rubber seals, but these O-rings use compounds specifically chosen for agricultural applications. They resist swelling from petroleum-based carriers, won’t degrade from fertilizer salts, and maintain their flexibility through temperature extremes from dawn to midday spraying.

Good to Know

When rebuilding your pump, replace all the O-rings in the set even if some look okay – it’s cheap insurance against having to tear things apart again mid-season. Clean all sealing surfaces thoroughly and lubricate the new O-rings with a bit of the fluid you’ll be pumping to prevent installation damage.
