Description
When hydraulic fluid starts showing up where it shouldn’t or you notice your three-point hitch losing pressure, chances are a worn O-ring is letting you down. One failed O-ring can drain hydraulic systems, create fuel leaks, or allow air into critical systems. These Buna-N rubber O-rings provide the reliable sealing your equipment needs to keep fluids where they belong and maintain proper system pressure.
What You’re Getting
- High-quality 70 durometer Buna-N rubber that resists oils, hydraulic fluids, and temperature swings
- Precision dimensions (7/8 inch ID, 1-1/8 inch OD, 1/8 inch cross-section) for exact-fit sealing
- Ten-pack quantity so you’ll have spares on hand for repairs and maintenance
- Versatile sealing for hydraulic fittings, fuel connections, oil housings, and equipment joints
Built for Real Farm Work
For use in plumbing, hydraulics, heavy equipment, automotive, irrigation and more. O-rings 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. Whether you’re servicing loader cylinders, replacing hydraulic hoses, or maintaining PTO systems, these O-rings handle the pressure and temperatures your equipment demands.
Made to Last
Despite their simplicity, O-rings face harsh conditions. Heat cycles cause them to harden and lose elasticity. Chemical exposure from fuels and fluids degrades rubber compounds. These Buna-N O-rings resist the chemicals and temperature cycles that destroy ordinary rubber, giving you dependable sealing performance season after season.
Installation Notes
Replace O-rings whenever disturbing sealed connections – reusing old O-rings invites leaks. Clean sealing surfaces thoroughly; scratches or debris prevent proper sealing. Lubricate O-rings with compatible fluid before installation to prevent rolling or tearing. Keep an assortment of common sizes in your parts inventory. Having the right size on hand beats waiting for parts when something needs fixing.
