Welcome to learning about NBR rubber gaskets
NBR rubber gaskets are the industry standard for sealing applications that use oils, fuels, and petroleum-based fluids. They are highly selected due to their high tensile strength, low compression set, and abrasion resistance. They are very chemically resistant to oils, solvents, and petrol.
The hardness ranges from 40 Shore A to 90 Shore A, and NBR rubber gaskets are not suitable for exposure to sunlight, UV light, ozone, general outdoor weathering, harsh chemicals, acids, ketones, and many others.
