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.

These work great on an LS Crank sensor. A little tighter fit than factory.

I got these to hold a paper roll in place that was on a tube. They were supposed to create friction. However, it did not work, probably because I had the wrong size. I wish you better luck. They are well made and should accomplish the task for the size you purchase.

Same size as the one I needed. I measured it to be the same as the description on these. It worked out to fit my oil filler tube cap. My old one was not flexible and getting brittle.

Second O-Ring purchase as the first one I bough didn't fit. However, I only needed one and you can't buy just one, so the balance of these were added to my out-of-control O-Ring inventory... Performance-wise, these work fine and seem of reasonablt quality...

Bought to replace the worn out oring on my Afco brand Small Block Chevy swivel water neck. Fits perfectly and should also work for other brands like Speedway. Much cheaper than the speed shops and I now have extras as spares.
