About This Product
These little rubber rings are total workhorses.

Othmro’s nitrile O-rings measure 43mm outer diameter, 40mm inner diameter, and 1.
5mm wide – a handy metric size that fits all sorts of sealing jobs.
You get 25 of them, so you’ll have plenty for repairs or projects.
Nitrile rubber (NBR) is the real deal – resists oil, grease, hydraulic fluids, and stands up to heat and wear.

That’s why they’re awesome for cars, plumbing, pumps, compressors, and even electronics.

The round cross-section makes ’em flexy and easy to install – just pop ’em between mating surfaces and they’ll seal tight against pressure and fluid leaks.

They handle mineral oils and alcohols like a champ, but keep ’em away from ozone or direct sun because that’ll shorten their life.

Whether you’re fixing a faucet, a trailer, or a power tool, these O-rings get the job done without breaking a sweat.
