Othmro Nitrile Rubber O-Rings – 85mm OD X 75mm ID X 5mm Width, Metric Sealing Gasket, 10-Pack, Oil & Wear Resistant

About This Product

Need some solid O-rings for a repair or project?

These Othmro ones are made from nitrile rubber (NBR), which is tough stuff – it resists oil, grease, hydraulic fluid, alcohol, and mineral oils, so it's great for automotive and plumbing jobs.

This pack gives you 10 rings, each with an 85mm outer diameter, 75mm inner diameter, and 5mm width.
That's a nice chunky size for sealing flanges, valves, cylinders, or even engines.
The round cross-section design helps create a tight pressure seal between overlapping surfaces.

NBR also handles heat, abrasion, and UV better than many other rubbers, though you'll want to avoid using it around acetone, ether, or ozone-heavy environments like welding gear or motors with sparks.

Installation is easy – they're flexible and just pop into place.

Use them for power supplies, trucks, trailers, pumps, furniture, or general maintenance.

They come in black, and Othmro offers various sizes if you need something different.

Reliable, affordable, and ready to work.
