Description
Nothing stops a spray job faster than a pump that won’t hold pressure or starts leaking all over the place. When your AR pump starts acting up with pressure drops, erratic flow, or fluid seeping from fittings, worn o-rings are usually the culprits. This handy kit gets you back to spraying with all the seals you need to restore your pump’s performance.
What You’re Getting
- Complete set of o-rings sized specifically for AR pump applications
- Chemical-resistant rubber compounds that handle herbicides, fertilizers, and cleaning solutions
- Precision-molded seals that maintain proper compression under high pressure
- Quality materials that stay flexible through temperature swings and chemical exposure
Built for Real Farm Work
AR pumps power spray equipment across thousands of farms, from ATV sprayers and pull-behind rigs to three-point mounted units. Whether you’re applying post-emergent herbicide, liquid fertilizer, or washing down equipment, these pumps see heavy use during spray season. This kit covers the common seal points where pressure loss and leaks typically develop.
Made to Last
Farm spray pumps deal with aggressive chemicals and constant pressure cycling that tests every seal. These o-rings are formulated to resist swelling and degradation from common agricultural chemicals while maintaining their sealing ability through thousands of pressure cycles. Quality rubber compounds stay pliable even after sitting through winter storage.
Good to Know
Keep this kit handy during spray season since o-ring failures always seem to happen at the worst times. Clean all sealing surfaces thoroughly before installing new o-rings, and a light coating of compatible grease helps with installation. If one seal has failed, it’s smart to replace any others that are easy to access while you’ve got things apart.
