Description

When hydraulic fittings weep, fuel filters leak, or coolant connections drip, the problem usually comes down to one thing—a worn-out O-ring. These little rubber seals might look simple, but they’re the critical barrier between a properly sealed system and a mess on your shop floor. This 10-pack of quality Buna-N O-rings keeps you stocked for those inevitable seal jobs.

What You’re Getting

70 durometer Buna-N rubber that handles hydraulic fluid, fuel, and coolant exposure
Precise 1-1/8″ inside diameter and 1-3/8″ outside diameter for exact fitment
1/8″ cross-section width provides proper groove fit and sealing force
10-pack quantity so you’ve got spares when that emergency repair comes up
Direct replacement for worn original seals—no guesswork on sizing

Built for Real Farm Work

These O-rings work across your entire operation—plumbing repairs, hydraulic system maintenance, heavy equipment service, automotive fixes, and irrigation system upkeep. Whether you’re rebuilding a hydraulic cylinder on your loader, replacing seals in a fuel filter housing, or fixing a leaky fitting on your planter’s hydraulic drive, this size handles a wide range of sealing jobs.

Made to Last

Farm equipment puts O-rings through the wringer—heat cycles, chemical exposure, and constant pressure changes all take their toll. These Buna-N seals resist the fuel, hydraulic oil, and coolant exposure that destroys cheaper rubber compounds. The 70 durometer rating provides the right balance of flexibility for sealing and firmness to resist extrusion under pressure.

Good to Know

Always clean the groove thoroughly before installing new O-rings—any debris or old seal material will cause leaks. A light coating of the system fluid helps installation and prevents the O-ring from twisting or rolling. Replace O-rings at the first sign of hardening or cracking rather than waiting for failure.
