[Jada Industry and Trade to recommend star product]-o-ring o-ring design Tianjin oil through the appropriate choice of rubber material and appropriate formulations to achieve the oil, water, air, gas and a variety of chemical media effectively seal . Wide temperature range (- 60 ℃ ~ + 220 ℃), fixed working pressure up to 1500Kg/cm2 (with reinforcement ring and used). - The design is simple, compact oil o-rings, rubber O-ring assembly and disassembly to facilitate cross-sectional structure is extremely simple, and there is self-sealing, reliable sealing performance. As the rubber O-ring structure itself and the site is extremely simple to install, and has formed o-ring standardization oil prices, it is very easy to install replacement. - Material varieties can be selected according to different fluid: There nitrile rubber (NBR), Viton (FKM), silicone rubber (SIL), EPDM rubber (EPDM), chloroprene rubber (CR), natural rubber (NR) hydrogenated nitrile rubber (HNBR), butyl rubber (IIR), silicon fluorine rubber (FLS) and so on. [Jada Industry and Trade to recommend star product-o-ring] nitrile rubber O-ring suitable for petroleum-based hydraulic fluids, glycol hydraulic oil lines, two ester-based lubricants, gasoline, water, silicone grease, silicone oil, etc. medium used. Nitrile rubber is currently the most widely used and least expensive rubber seals. Not to polar solvents oil o-ring type, e.g. ketones, ozone, nitro hydrocarbons, MEK and chloroform. General temperature range of -40 ~ 120 ℃. Varies on material, the use of static pressure is less than 20Mpa. Sometimes for dynamic, dynamic pressure when using less than 5Mpa, and semiconductor vacuum seal. Sizes to choose from are: cross-sectional diameter of about 0.35 ~ 12mm inside diameter up to 1000mm and above.
