Description

When hydraulic fittings start leaking or air sneaks into your system, it’s usually a worn o-ring that’s causing the trouble. These little rubber seals might look simple, but they do a big job keeping fluids where they belong and contaminants where they don’t. This particular size fits a lot of common hydraulic connections on tractors and implements.

What You’re Getting

Perfect seal for 5/8″ inside diameter fittings – no guesswork on sizing
Buna-N rubber construction that handles hydraulic oil, fuel, and most farm chemicals
70 durometer rating means it’s firm enough to seal but flexible enough to compress properly
Pack of 10 gives you spares for the toolbox – you’ll need them eventually

Built for Real Farm Work

These o-rings work in all kinds of hydraulic systems – plumbing, hydraulics, heavy equipment, automotive, irrigation and more. Whether it’s a loader valve, remote hydraulic outlet, or implement connection, this size shows up in a lot of places on farm machinery.

Made to Last

Buna-N rubber is the go-to material for most farm applications because it handles temperature swings and doesn’t break down when it touches hydraulic fluid or diesel. Made of 70 Durometer Buna-N Rubber – that’s the right balance of firmness and flexibility for a good seal.

Good to Know

Always replace o-rings in pairs if you’re working on a connection – if one’s worn out, the other probably isn’t far behind. Keep a few spares in your toolbox since these have a way of rolling off the workbench and disappearing into the shop floor.
