Description
When you’re out fixing hydraulic leaks on the tractor or getting your planter ready for spring, the last thing you want is to have the wrong O-ring. This little rubber ring might look simple, but it’s what keeps your hydraulic fluid where it belongs—in the system, not on the ground. For use in plumbing, hydraulics, heavy equipment, automotive, irrigation and more, this O-ring is sized to handle the tight spots where standard seals just won’t fit.
What You’re Getting
- 1/16″ width gives you a low-profile seal that fits in narrow grooves without binding
- 3/4″ inside diameter and 7/8″ outside diameter for precise fitment in compact fittings
- 90 durometer rating means this rubber stays firm under pressure but flexible enough to seal properly
- Buna-N construction resists hydraulic oil, diesel fuel, and the chemicals you encounter on the farm
Built for Real Farm Work
This size O-ring shows up in all kinds of places—hydraulic quick-couplers, small cylinder fittings, valve bodies, and anywhere you need a reliable seal in a tight space. Whether you’re working on a compact tractor’s loader circuit or fixing a leaky connection on your spray rig, having the right size O-ring on hand saves you a trip to town.
Made to Last
Farm equipment puts seals through the wringer with temperature swings, pressure spikes, and exposure to all kinds of fluids. The 90 durometer rating means this O-ring is harder than the standard 70 durometer versions, giving you better resistance to extrusion and longer life in high-pressure applications.
Installation Notes
Clean the groove thoroughly before installing—any dirt or old rubber can cause leaks. A light coat of hydraulic oil helps the O-ring slide into place without nicking. If you’re working with really tight tolerances, make sure your fitting isn’t over-torqued, which can pinch the seal.
