Buna-N O-Ring Kit for Agricultural and Equipment Hydraulic Systems – 10 Pack

Description

You know that sinking feeling when hydraulic fluid starts pooling under your tractor or equipment. 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 hydraulic cylinders on your loader, replacing fuel filters on your Deutz engine, repairing coolant connections, or maintaining air brake systems, proper O-ring seals prevent the leaks that lead to bigger problems. One failed O-ring can drain hydraulic systems, create fuel leaks, or allow air into critical systems. These quality Buna-N rubber O-rings get you back to work fast and keep your systems sealed tight.

What You’re Getting

• Durable 70 durometer Buna-N rubber that handles pressure and temperature swings
• Precise 3/16″ width with 3-7/8″ inside diameter and 4-1/4″ outside diameter for proper sealing
• Ten-pack quantity means you’ll have spares on hand for future repairs
• Chemical resistance to hydraulic fluids, fuel, and most agricultural chemicals
• Professional-grade quality that performs like OEM seals

Built for Real Farm Work

These O-rings work across hydraulic systems on tractors and equipment from all major brands. They’re sized for common hydraulic fittings, loader cylinders, and system connections found throughout agricultural and construction equipment. Whether you’re fixing a leaky hydraulic quick-coupler, sealing a cylinder fitting, or replacing worn seals in equipment connections, this size handles many everyday repair jobs.

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. Compression set occurs when O-rings remain squeezed in one position too long. Mechanical damage happens during installation or from system pressure cycles. These Buna-N rings are engineered to handle all of that abuse while maintaining their sealing properties season after season.

Good to Know

Always clean the O-ring groove thoroughly before installation and apply a light coat of compatible lubricant to the new seal. Don’t use petroleum jelly or grease that can degrade rubber compounds. Keep your spare O-rings in a cool, dry place away from direct sunlight to maintain their flexibility. A small investment in quality seals saves big money on hydraulic fluid and prevents equipment downtime.
