Description
When you’re dealing with hydraulic leaks or replacing seals during maintenance, having the right O-ring on hand can save your day. These 4-3/4″ inside diameter Buna-N O-rings are the workhorses of agricultural equipment—they seal hydraulic cylinders, keep fluid connections tight, and prevent the kind of leaks that’ll leave you stranded in the field.
What You’re Getting
- 70 durometer Buna-N rubber that stands up to hydraulic fluid, diesel fuel, and temperature swings
- 1/4″ cross-section width provides the right squeeze for reliable sealing
- Sold in a 10-pack so you’ll have spares when you need them most
- Direct replacement for worn seals in cylinders, fittings, and hydraulic components
Built for Real Farm Work
These O-rings work in all kinds of agricultural equipment where this size seal is called for—hydraulic cylinders on loaders and implements, fuel system connections, and various equipment fittings. Whether you’re fixing a leaky cylinder on your front-end loader or replacing seals during routine maintenance, proper sealing keeps your equipment running and prevents costly fluid loss.
Made to Last
Buna-N rubber is the go-to material for farm equipment because it handles the conditions you deal with every day. It stays flexible in cold weather, doesn’t get gummy from diesel contact, and maintains its seal under the pressure cycling that happens in hydraulic systems. The 70 durometer rating gives you the right balance of flexibility and strength.
Good to Know
When installing these O-rings, a light coating of the system fluid helps them seat properly without pinching. Clean the groove thoroughly and check for sharp edges that could nick the new seal. Having a 10-pack means you can tackle multiple repairs at once or keep spares in your toolbox for when leaks show up at the worst possible time.
