Description
When you’re dealing with hydraulic leaks, fuel system drips, or coolant seepage, a failed O-ring is usually the culprit. These small but critical seals appear everywhere on modern equipment – hydraulic fittings, fuel system connections, oil filter housings, coolant joints, and air system fittings all depend on these simple but crucial seals. This 10-pack of Buna-N O-rings gives you the right size seal to stop leaks and keep your equipment running clean.
What You’re Getting
- Ten high-quality Buna-N rubber O-rings sized at 1-3/4″ inside diameter by 2-1/8″ outside diameter
- 70 durometer hardness that handles hydraulic pressure without being too stiff or soft
- 3/16″ cross-section width that fits standard agricultural equipment grooves
- Oil and fuel resistant compound that won’t swell or deteriorate from fluid contact
- Bulk packaging means you’ll have spares when you need them most
Built for Real Farm Work
These O-rings work in hydraulic cylinders, fuel system fittings, coolant connections, and anywhere you need a reliable seal on tractors, loaders, combines, and implements. The Buna-N rubber compound handles the temperature swings and chemical exposure that farm equipment sees every day, from sub-zero winter storage to hot summer fieldwork.
Made to Last
Despite their simplicity, O-rings face harsh conditions – heat cycles cause them to harden and lose elasticity, while chemical exposure from fuels and fluids degrades rubber compounds. These 70 durometer Buna-N seals are engineered to resist those problems and maintain their sealing ability through years of service.
Installation Notes
Always clean the groove and inspect for nicks or scratches before installing a new O-ring. A light coat of the system fluid helps the O-ring slip into place without twisting or rolling. Keep these stored in a cool, dry place away from direct sunlight – rubber deteriorates faster when exposed to UV light and heat.
