O-ring Gasket can become brittle and crack after years of use.Also it is unique gasket made of metal tube which is formed and buttwelded into a round shape or other shapes.Moreover,it has the different materials of NBR, EPDM, FKM, VT, Silicon rubber etc.Compared with other plastics,it has excellent high temperature corrosion and temperature.More than that,it can be resistance to media of water, seawater, steam, diluted acid or alkali, gases, alcohols, salt solutions etc. under temperature and pressure.
Furthermore,as O-ring Gasket is usually made of asbestos Fibre, rubber and heat-resisting packing material, compressing it to thick paper,thus it has a good resistant of high/low temperature, oil,water, tensile, elongation, and has a good compression set,etc.Yet,it has the unique characteristics of oil proof,heat resisting ,waterproof,ailkali proof and high soundness etc.Also it is widely used in seals, valve seats and valve stem seals.
Additionally,O-ring Gasket can be widely used in bathroom product, valve, faucet, machine, hydraumatic, pneumatic and automobiles.Usually,it can be used for the equipment in water, steam, etc.and used as sealing material in the joints of pipeline.What's more,the gasket is equipped with various advantages and it can be sealed with low tightening force, can be formed into various shapes according to the shapes of mating face and can be used for high temperature, high pressure and ultra-vacuum services. It is the most suitable gasket for sealing such machinery and equipments that space factor and compactness are accounted much of for their designs. Special surface coating is available according to necessity.
