Description
Nothing stops field work faster than a hydraulic leak, and more often than not, it’s a worn-out O-ring that’s the culprit. Whether it’s dripping from your loader connections, seeping around cylinder seals, or making a mess under your tractor, these small rubber rings are what keep your hydraulic systems running clean and tight. This 1/2″ inside diameter by 5/8″ outside diameter Buna-N O-ring gives you the reliable seal you need to get back to work.
What You’re Getting
- Made from 70 durometer Buna-N rubber that handles hydraulic fluid, temperature swings, and the constant pressure changes your equipment dishes out
- 1/16″ cross-section width provides the right squeeze for a proper seal without over-compressing
- Ten-pack means you’ll have spares on hand when the next seal gives up—and there’s always a next one
- Direct replacement size that fits hundreds of different hydraulic fittings and cylinder applications
Built for Real Farm Work
These O-rings work in plumbing, hydraulics, heavy equipment, automotive, and irrigation systems—basically anywhere you need a reliable seal that won’t quit when the pressure’s on. From loader bucket cylinders to three-point hitch lift arms, from hydraulic quick-couplers to PTO pump connections, this size fits more applications than you’d think.
Made to Last
Buna-N rubber is the go-to choice for hydraulic applications because it resists petroleum-based fluids while staying flexible in cold weather and holding up to summer heat. The 70 durometer rating gives you the right balance of firmness for sealing and flexibility for installation, so these rings will do their job without tearing during assembly.
Good to Know
Keep a few of these in your toolbox—they’re one of those parts you don’t think about until you need them, and when you do, you need them right now. Sold by the ten-pack, so you’ll have extras for the inevitable “while we’re in there” moments that happen during repairs.
