Buna-N Rubber O-Ring Set for Hydraulic and General Sealing Applications

Description

When that hydraulic cylinder starts weeping or your loader starts feeling sluggish, the problem’s usually smaller than you think. 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. One failed O-ring can drain hydraulic systems, create fuel leaks, or allow air into critical systems. This 10-pack of 1-7/8″ x 2-1/8″ Buna-N rubber O-rings gives you the seals you need to keep things tight.

What You’re Getting

• High-quality Buna-N rubber construction that handles hydraulic fluid, fuel, and oil without breaking down
• 70 durometer hardness provides the right balance of sealing and flexibility for most farm applications
• Precise 1/8″ cross-section fits standard O-ring grooves in fittings and components
• Ten O-rings per package means you’ll have extras when the next one needs replacement
• Universal sizing works across many brands and applications—not just one specific machine

Built for Real Farm Work

These O-rings work anywhere you need a reliable seal in the 1-7/8″ inside diameter size. 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. From hydraulic pump fittings to transmission case seals, these are the workhorses that keep fluids where they belong.

Made to Last

Buna-N rubber stands up to the punishment farm equipment dishes out. 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. This compound resists those problems better than generic rubber, staying flexible through temperature swings and chemical exposure that would destroy cheaper seals.

Good to Know

Measure carefully – both diameter and cross-section must match exactly. Clean sealing surfaces thoroughly; scratches or debris prevent proper sealing. Lubricate O-rings with compatible fluid before installation to prevent rolling or tearing. Replace O-rings whenever disturbing sealed connections – reusing old O-rings invites leaks. Keep these in your parts drawer—when one O-ring fails, you’ll want spares handy.
