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.

They seem to be high quality just an inaccurate size.

I was very happy. The sizes are accurate. I wanted these to replace an o ring on a Vortex optics picatinney bubble level battery compartment. I measured the old one found the size in searching and ordered it. The size was exactly what I wanted. Awesome. The sizes they state are right on the money.

The O ring is of a cheap quality and the size was not accurate.

I have used silicone grease to seal up platinum preppies but I've wanted to switch over to o-rings. This is a perfect fit and works great. It will seal up similarly sized pens like some Jinhao pens. But they won't seal all pens- the ID isn't tight enough for other pens.Anyway, this works great for Platinum Preppy, Meteor, and other similarly sized pens. Great price for 50 of them!

These fit my 13mm earrings/plugs great, but they are very thin. I was looking to add weight to my front-heavy earrings so these don’t quite meet my needs, but they’re great if you’re looking for o-rings that aren’t obvious.

I use these on my Platinum Preppy fountain pens, so I can fill the entire barrel with ink. These rings fit these specific pens. Plus, I got a lot for the price; good deal!

I bought these to use with my gushed earrings. Makes it much easier to switch out earrings.

I needed a small 1mm width, flexible drive belt. These were perfect. I ordered 3 ID sizes: 10mm ; 11mm; and 12mm. All 1mm width sizes of this O-ring to make sure I had a suitable fit. I needed a 1mm width and not sure of the inside / ID length. The OD did not concern me as long as the ID and Width would fit. The old one had stretched as it was used as a small drive belt on a device. I could not get an accurate measurement. Seem to be about 10mm -12mm between the 2 pulleys and the old belt was 1mm wide (round). I was not sure of the length required just the 1mm width. These O-rings worked fine as a drive belt for my device... No slipping as with the original. They should be fine for sealing fittings, etc. as they seem to be of uniform shape , well made and of good quality.
