Sealingrubberapronring Pipe Fitting Hardware Sealing Ring

PROS: 1. Good oil resistance, water resistance, solvent resistance and high pressure oil resistance. 2. Good compression distortion, abrasion resistance and elongation. 3. It is used for making fuel tank, lubricating oil tank and rubber parts, especially sealing parts, which are used in fluid medium such as petroleum hydraulic oil, gasoline, water, grease, silicone oil, diester lubricating oil, alcohol hydraulic oil, etc. . The static service pressure is less than 20Mpa depending on the material. Sometimes also used for dynamic, dynamic use of pressure less than 5MPA, and semiconductor vacuum seal. Available size specifications are: cross-sectional diameter about 0.35-12mm inside diameter up to 1000mm and above.
simple structure, integral groove design, reduce processing and design costs;-compact structure, small parts shape;-easy installation, reduce the risk;-can be applied to a variety of sealing problems, such as: static seal, dynamic seal, single-acting and double-acting seal; - Wide Selection of materials for most fluids.
The properties show that rubber has excellent oil-resistant properties, and its temperature range can be extended to-55 ° C ~ 125 ° C (- 67 ° f ~ 275 ° F) by special formulation. Rubber is a copolymer of Butadiene and acrylonitrile, the acrylonitrile (ACN) content of NBR molecule is variable (18 to 50%) , which can adjust the oil resistance and low temperature resistance of the material. The higher the acrylonitrile content is, the better the properties of the lubricating oil and the fuel oil are, but the low temperature elasticity becomes worse. Conversely, the lower the acrylonitrile content, the better the resistance to dripping temperature, but to sacrifice the resistance to lubricants and fuel oil properties. The specifications AN and Ms 0 ring specifications require a low acrylonitrile rubber formulation to ensure its low temperature resistance. Rubber has excellent compression deformation, tear resistance, wear resistance, but does not have good weather and ozone resistance, and heat resistance is only medium.
