Vertex Rubber manufactures high-quality nitrile (NBR) rubber gaskets with excellent oil, fuel, and grease resistance. Our nitrile gaskets are the most cost-effective choice for automotive, hydraulic, and general industrial sealing applications, operating reliably from -30°C to +120°C.
Nitrile rubber (NBR), also known as Buna-N, is a synthetic rubber copolymer of acrylonitrile and butadiene. It is the most widely used elastomer in the sealing industry due to its excellent resistance to oils, fuels, greases, and hydraulic fluids. The acrylonitrile content determines the material's oil resistance and low-temperature flexibility — higher acrylonitrile content provides better oil resistance but reduced flexibility at low temperatures.
At Vertex Rubber, we offer nitrile gaskets in a range of acrylonitrile content (18% to 50%) to suit different application requirements. Our NBR gaskets are compression moulded and die-cut to precise tolerances, ensuring reliable sealing performance in demanding industrial environments.
