Description

When your pressure washer starts losing pressure or your diaphragm pump develops leaks, worn o-rings are usually the culprit. Nothing stops a cleaning job faster than a pump that won’t hold pressure, and trying to work around leaky seals just makes the problem worse. This AR Pumps o-ring kit gives you the essential seals to get your equipment sealed up tight and working like it should.

Complete set of precision-sized o-rings for proper sealing throughout your pump
High-quality rubber compounds that resist chemicals and temperature extremes
Direct AR Pumps replacement parts that fit exactly like the originals
Convenient kit format so you have all the seals you need for a complete service

Built for Real Farm Work

AR Pumps are workhorses in agricultural applications, powering everything from livestock watering systems to equipment cleaning stations. Whether you’re running a pressure washer for cleaning dairy equipment, washing down livestock areas, or maintaining farm machinery, these pumps see hard use in demanding conditions. The o-rings in this kit handle exposure to detergents, disinfectants, and the temperature swings that come with outdoor use.

Made to Last

These aren’t generic hardware store o-rings. AR Pumps engineers these seals specifically for pump applications where they face constant pressure cycling, chemical exposure, and the vibration that comes with pump operation. The rubber compounds maintain their flexibility and sealing ability even after thousands of pressure cycles.

Installation Notes

Always replace o-rings as a complete set when servicing your pump – if one has failed, the others are likely close behind. Clean all sealing surfaces thoroughly and use a light coating of compatible lubricant during installation. Never reuse old o-rings, even if they look okay, as the few dollars saved isn’t worth a comeback leak.
