Buna-N Rubber O-Ring 10-Pack for Hydraulic Systems and Equipment Applications

Description

When you’re dealing with hydraulic leaks or planning maintenance on your equipment, having the right o-rings on hand can save you time and money. This 3-inch inside diameter Buna-N o-ring is a common size that shows up in hydraulic cylinders, pumps, and valve assemblies across all kinds of farm machinery. The Buna-N rubber construction makes it ideal for hydraulic systems, and you’ll appreciate having a 10-pack when you’re doing repairs.

What You’re Getting

• 3-inch inside diameter with 3-3/8-inch outside diameter fits standard hydraulic grooves
• 3/16-inch cross-section provides the right seal thickness for most applications
• 70 durometer Buna-N rubber handles hydraulic fluid and temperature swings like a champ
• Pack of 10 means you’ve got spares for future repairs or multiple seals on the same job
• Direct replacement for worn or damaged o-rings in hydraulic systems

Built for Real Farm Work

This size o-ring works in hydraulic systems across heavy equipment, automotive, and irrigation applications. Whether you’re rebuilding a hydraulic cylinder on your loader, fixing a valve on your sprayer, or sealing connections in your irrigation system, this is the same quality rubber that equipment manufacturers use from the factory.

Made to Last

Buna-N rubber is the go-to choice for hydraulic applications because it stands up to petroleum-based fluids and doesn’t get brittle in cold weather or soft in the heat. The 70 durometer rating gives you the right balance of flexibility for sealing and firmness to resist extrusion under pressure.

Good to Know

Before installing, make sure the groove is clean and free of nicks or scratches that could cut the new o-ring. A light coat of hydraulic fluid on the o-ring makes installation easier and helps prevent damage. Keep the extras in your toolbox—you’ll be surprised how often this size comes up in repairs.
