When you’re dealing with leaky hydraulics or brake systems on your tractor, it’s usually the small stuff that gets you – and O-rings are about as small as they come. But don’t let their size fool you. A worn O-ring in the wrong spot can shut down your whole operation, leaving you with puddles of expensive hydraulic fluid or even worse, brake failure when you need stopping power most. This pack of ten Buna-N O-rings keeps you ready for those inevitable seal replacements.
What You’re Getting
- Ten high-quality Buna-N rubber O-rings built to handle hydraulic pressure and brake fluid
- 1/8″ width with 2-1/4″ inside diameter provides secure sealing in tight spaces
- 70 durometer hardness gives you the flexibility to seal properly while resisting damage
- Chemical resistance to hydraulic oils, brake fluids, and the harsh chemicals your equipment faces
- Pack of ten means you’ll have spares when you need them most
Built for Real Farm Work
These O-rings work across a wide range of applications – from hydraulic pumps and cylinders to brake systems and plumbing connections. Whether you’re rebuilding a hydraulic pump, fixing a leaky cylinder, or sealing up brake components, these rings handle the pressure and chemical exposure that comes with farm equipment. They’re the same quality seals that equipment manufacturers use in factory assemblies.
Made to Last
Buna-N rubber is the go-to material for agricultural seals because it handles both petroleum-based hydraulic oils and glycol brake fluids without swelling or cracking. The 70 durometer hardness gives you that sweet spot – soft enough to form a good seal but firm enough to resist extrusion under pressure. These rings maintain their flexibility through temperature swings from cold morning startups to hot summer field work.
Good to Know
Keep the package sealed until you’re ready to use them – exposure to sunlight and ozone can age rubber seals prematurely. When installing, a light coating of the fluid they’ll be sealing helps them slip into place without rolling or twisting. If you’re doing a complete rebuild, replace all the O-rings even if some look okay – they’ve all seen the same wear and contamination.
