Description
When you’re dealing with hydraulic leaks, fuel system problems, or water pump issues, having the right o-ring on hand can save your day. This 3-inch inside diameter o-ring is just the right size for many larger hydraulic fittings and pump housings on farm equipment. It’s made from 70-durometer Buna-N rubber that handles the pressure and temperature swings your machinery dishes out.
What You’re Getting
- Ten high-quality o-rings per package so you’ve got spares for future repairs
- 70-durometer Buna-N rubber that stays flexible in cold weather and won’t harden in heat
- Precise 1/8-inch cross-section provides reliable sealing in standard AS568 grooves
- Chemical resistance to hydraulic fluid, diesel fuel, and most farm chemicals
- 3-inch inside diameter fits larger hydraulic components and pump housings
Built for Real Farm Work
This size o-ring shows up in hydraulic pumps, larger fuel system components, and water pumps on everything from compact tractors to big combines. You’ll find it sealing pump covers, filter housings, and transmission cases where a reliable seal means the difference between getting the job done and being stuck in the field.
Made to Last
Buna-N rubber is the gold standard for farm equipment seals because it handles temperature extremes from winter storage to summer heat without cracking or losing its seal. The 70-durometer hardness gives you the right balance of flexibility for sealing and firmness for durability under pressure.
Good to Know
Clean the groove thoroughly before installing – any dirt or old rubber bits will cause leaks. A light coating of the fluid being sealed helps installation and prevents the o-ring from twisting. Keep extras in your toolbox because when you need one, you usually need it right away.
