WUXI HOLLY Nitrile Rubber Heat Insulation Tube is a formidable tubing material used in high fuel usage environments.Nitrile tube has a concentration of Acrylonitrile-butadiene making it ideal for oils and solvents. The nitrile tubes are flexible and resilient.With such a high concentration of Nitrile in the composition of the tube, the nitrile rubber tube has limited stretching ability.
