Description

When you’re dealing with hydraulic leaks, fluid contamination, or that annoying drip under your equipment, it usually comes down to a worn O-ring. This 2-7/8 inch inside diameter O-ring is the right size for many hydraulic fittings, valves, and connections on farm equipment. Getting the seal right means keeping your hydraulics working properly and avoiding costly fluid loss or system damage.

What You’re Getting

70 durometer Buna-N rubber that handles hydraulic fluid, grease, and temperature swings
Precise 1/8 inch cross-section fits standard hydraulic grooves without binding
Ten O-rings per pack so you’ll have spares when you need them most
Quality construction that seals tight without over-compressing or cracking

Built for Real Farm Work

This size O-ring shows up in hydraulic systems across tractors, loaders, and implements where reliable sealing matters. Whether you’re working on hydraulic cylinders, valve blocks, or fitting connections, this is a common size that keeps hydraulic fluid where it belongs and dirt where it doesn’t.

Made to Last

Buna-N rubber handles the oil, heat, and pressure that hydraulic systems dish out every day. The 70 durometer rating gives you the right balance—flexible enough to seal properly but firm enough to resist extrusion under pressure. These O-rings maintain their sealing properties through temperature changes and repeated pressure cycles.

Good to Know

Always clean the groove thoroughly before installing a new O-ring, and check that the groove depth matches the O-ring cross-section. A light coating of hydraulic fluid or compatible grease during installation helps prevent damage and ensures proper seating. Keep extras in your toolbox because O-rings always seem to fail at the worst possible times.
