Description

When your sprayer pump starts weeping fluid around the body or you’re losing pressure on your liquid fertilizer rig, a worn body seal O-ring is often the culprit. This little seal might not look like much, but it keeps your pump body tight and your chemicals where they belong—in the tank, not on the ground underneath your equipment.

What You’re Getting

Precision-molded O-ring that creates a leak-proof seal between pump body halves
Chemical-resistant material that stands up to fertilizers, herbicides, and other ag chemicals
Exact factory dimensions ensure proper compression without over-squeezing
Direct replacement—no modifications needed for installation

Built for Real Farm Work

This O-ring is designed specifically for Ace FMC and FMC-HYD series centrifugal pumps commonly found on sprayers, nurse tanks, and liquid applicators. These pumps handle everything from water transfer to chemical application on row-crop operations, running at pressures up to 120 PSI with flow rates that keep your operation moving efficiently.

Made to Last

Farm chemicals are tough on seals, but this O-ring is formulated to resist the breakdown that comes from constant exposure to fertilizers and crop protection products. The material stays flexible through temperature changes and maintains its sealing properties even after thousands of pump cycles during busy seasons.

Good to Know

Installation is straightforward—just split the pump body, clean the old O-ring groove thoroughly, and seat the new ring evenly. A light coat of compatible lubricant helps prevent pinching during assembly. While you’ve got the pump apart, it’s a good time to check the impeller and other seals for wear.
