Description

Whether you’re rebuilding a hydraulic cylinder, fixing a leaky pump fitting, or servicing an implement’s hydraulic connection, nothing’s more frustrating than having the right size O-ring sitting on your parts shelf when you need it. This versatile 3/32″ wide Buna-N O-ring fits common hydraulic applications in plumbing, hydraulics, heavy equipment, automotive, and irrigation systems. Having a 10-pack on hand means you’re always ready for that unexpected leak or planned maintenance.

What You’re Getting

Ten O-rings measuring 2-5/16″ inside diameter and 2-1/2″ outside diameter with 3/32″ cross-section width
70 Durometer Buna-N rubber construction that handles the pressure and chemical exposure of modern hydraulic fluids
Convenient 10-pack quantity – enough for multiple repairs or keeping spares on hand
Direct replacement for worn or damaged seals in hydraulic fittings, cylinder assemblies, and pump connections

Built for Real Farm Work

This O-ring size is commonly found in hydraulic systems on tractors, implements, and farm equipment where reliable sealing prevents expensive fluid loss and contamination. You’ll often see this size in hydraulic cylinder assemblies, pump mounting points, and various hydraulic fittings throughout your equipment. When hydraulic seals fail, you don’t just lose fluid – you lose the pressure needed to operate loaders, three-point hitches, and implement functions properly.

Made to Last

The 70 Durometer Buna-N rubber construction provides the right balance of flexibility and durability for hydraulic applications. This material resists the heat, pressure cycles, and chemical exposure that hydraulic systems dish out daily. Unlike cheaper substitutes, Buna-N maintains its sealing properties through temperature swings and doesn’t harden prematurely from hydraulic fluid contact.

Good to Know

Before installation, clean the O-ring groove thoroughly – any dirt or old seal fragments cause comeback leaks. Lubricate the new O-ring with a thin coat of clean hydraulic fluid during installation, never force it into place. If you’re working on hydraulic systems, having the right size O-ring ready saves trips to town and keeps repair jobs moving.
