- Temperature: -4℉ (-20°C) to 212℉ (100 °C)
Circular Cross-Section
- They are circular, round in cross-section.

- 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 used this 65mm gasket for a CPU wateblock application. The Barrow AM4 CPU waterblock had a very thin and flimsy oring which broke into several pieces. The 2.5mm thickness provided a vastly superior seal, and turned my copper paperweight into a serviceable CPU cooler. Incidentally, I also had to replace the cheap LEDs that failed within 30 seconds.My only complaint is the orings could have been softer and pliable, there isn't much flexibility and I had difficulty fitting the gasket into an irregular shape. But it worked and that's the bottom line.
