Description

When you’re dealing with hydraulic leaks or plumbing repairs around the farm, having the right o-rings on hand can save you a trip to town and keep your operation running. These Buna-N rubber o-rings are the go-to choice for sealing hydraulic fittings, irrigation connections, and all sorts of equipment where you need a reliable seal that won’t quit.

What You’re Getting

Ten quality o-rings made from 70 durometer Buna-N rubber that handles hydraulic fluid and temperature swings
Precise 3-5/8 inch inside diameter and 3-7/8 inch outside diameter for exact replacement fitment
1/8 inch cross-section width that fits standard groove dimensions
Chemical resistance to petroleum products, hydraulic oils, and most agricultural fluids
Flexible material that maintains sealing properties from cold winter mornings to hot summer field work

Built for Real Farm Work

These o-rings work great in tractor hydraulic systems, irrigation equipment, plumbing connections, and heavy machinery where fluid containment matters. Whether you’re repairing loader cylinders, fixing irrigation line connections, or maintaining hydraulic pumps and motors, this size fits a wide variety of agricultural applications where reliable sealing is critical.

Made to Last

Buna-N rubber stands up to the demands of farm life – it resists hydraulic oil, diesel fuel, and the temperature extremes you’ll find in field equipment. The 70 durometer rating gives you the right balance of flexibility for sealing and firmness for durability, so these o-rings keep working season after season.

Good to Know

Always clean the o-ring groove thoroughly before installing new seals – old rubber fragments or dirt will cause leaks. A light coat of hydraulic fluid or compatible lubricant on the new o-ring makes installation easier and prevents nicks from sharp edges. Keep extras in your toolbox because you never know when you’ll need them.
