3.1X134.4 Metric Nitrile O-Ring - 70A Durometer, 134.4 mm ID, 140.6 mm OD, 3.1 mm CS, Black (Pack of 10) Actual Dimensions: 5.291" ID, 5.535" OD, 0.122" CS , Metric Dimensions: 134.4 mm ID, 140.6 mm OD, 3.1 mm CS Temperature Range: -35°C (-31°F) to 120°C (248°F); Shelf-life: 15 Years These versatile o-rings perform well in petroleum based oils & fuels, aliphatic hydrocarbons, vegetable oils, silicone oils & greases, ethylene glycol, dilute acids, and water to below 100°C (212°F) Designed for use in a wide variety of sealing applications. This Nitrile o-ring is resistant to compression set, and tear/abrasion. 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 70A Durometer Nitrile o-ring has a round cross-section and can be used across a wide temperature range (-35°C/-31°F to 120°C/248°F). The durometer hardness of this Buna-N o-ring is 70A. Mr O-Ring has all your 70A durometer Buna-N o-ring needs covered with our extensive metric size range.
