About Mr O-Ring 5.7X144.3 Metric Nitrile O-Ring - 90A

Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants, and its relatively low price. Nitrile (Buna) provides excellent compression set, tear, and abrasion resistance - making these Nitrile o-rings extremely durable and long-lasting. The 90A Durometer Nitrile o-ring has a round cross-section and can be used across a wide temperature range (-20°C/-4°F) to 120°C/248°F). The durometer hardness of this Buna-N o-ring is 90A. Mr O-Ring has all your 90A durometer Buna-N o-ring needs covered with our extensive metric size range.
