NBR O-Ring
- Hardness: 70A
- Temperature: -4℉ (-20°C) to 212℉ (100 °C)
Circular Cross-Section
- They are circular, round in cross-section.
- Designed for use in a wide variety of sealing applications.
- Commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders.
Nitrile Butadiene Rubber O-rings
- Good mechanical properties and high wear resistance NBR. Good resistance to many petroleum oils, greases, hydraulic fluids, alcohol, mineral oil, and grease.
- Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight, and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.

I've given this five stars because they seem to be of good quality. I bought them as they were suggested as the right size for replacing factory originals when restoring old bicycles.However, if you are looking at these to refurbish 30+ year old Shimano bicycle QR skewers, this size o-ring is about a millimeter less thick than the originals, leaving a small gap in the groove. As these serve a primarily cosmetic function it's not a big deal, unless you're a perfectionist.
