Classification Function Table Of Rubber Sealing Ring

One, by category


  1.O type sealing ring series


It has fluorine rubber, nitrile rubber, silica gel, ethylene propylene rubber, double fluorine rubber and other materials. It is widely used in various machinery, resistant to various petroleum-based oils and various chemical media: the use of non-rubber can meet- Temperature range of 60℃-+200℃ (double fluorine rubber FFKM can reach more than 300 degrees through a specific curing method), the working pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static sealing) nitrile The expansion rate of rubber and gasoline-resistant blends (90,93,97) is 0.


  2.Y type sealing ring


   has fluorine rubber, nitrile rubber, chloro rubber and other materials, which are widely used in hydraulic, mechanical, pneumatic and other industries. The resistant petroleum base oil has excellent abrasion resistance, and the selection of different types of rubber can meet the temperature range of -60℃-+200℃.


  3.V type sealing ring


   is an axially acting elastic rubber sealing ring, used as a pressureless seal on the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for larger tolerances and angular deviations, can prevent internal grease or oil from leaking, and can also prevent external splashing or dust from entering.


  4. YX type sealing ring for hole


   Briefly describe the product use: used to seal the piston in a reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders. CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, Rubber Product Hardness: HS85±2°A Working temperature: TPU: -40~+80℃ CPU: -40~+120℃ Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion


  5. YX type hole with retaining ring


Brief description of product use: This standard applies to the use of YX type seals when the working pressure of the cylinder is greater than 16MPa, or when the cylinder is eccentrically stressed, it plays the role of protecting the seal. Working temperature: -40~+100℃ Working medium: hydraulic oil , Emulsion, aquatic product hardness: HS92±5A Material: PTFE


   2. Classified by material


  1. Silicone rubber series


   is equipped with advanced testing equipment, clean and dust-free workshop. Products are widely used in electronics, medical equipment, food and other industries.


  Glue types are selected from a variety of domestic and imported silica gels, and the operating temperature can meet -60°—+200°C. The products can meet the requirements of oil resistance, steam resistance, medical and edible transparent, high strength, flame retardant, conductive silicone rubber, etc.


  2. Fluorine rubber series products


Widely used in automobile, shipbuilding, military industry, electronic appliances and other industries, working temperature -40℃+200℃, resistant to fuel oil, high temperature, freon, superheated water, steam and excellent chemical resistance, welcome Customers choose to customize.


  3. PTFE series products


Polytetrafluoroethylene gasket has high temperature resistance and corrosion resistance, even at high temperatures, it will not interact with concentrated acids, alkalis or strong oxidants. It has been widely used as a sealing material, suitable for pipelines, flanges, and reaction Sealing devices on kettles, valves and containers. Special-shaped parts are produced according to user design drawings.


   4. Various miscellaneous pieces


  The materials are selected from nitrile, natural, fluorine rubber, silica gel, etc., which are widely used in automobiles, machinery, valves and other industries. Different types of rubber can meet the temperature range of -50℃-+200℃. The product has good wear resistance and flexural properties, and can be designed according to requirements.


   5. Metal rubber sealing ring


  The material is metal rubber, which is a homogeneous elastic porous material. It not only possesses the elasticity of rubber, but also has the excellent characteristics of metal, and can work at a temperature of -150~800℃. At the same time, it can be pressure-bearing, and has the dual functions of pressure-bearing and sealing within a certain range. Its purpose:


  (1) FRP pipes; FRP sand pipes; FRP pipe jacks; cable protection pipes; flue gas desulfurization pipes; coal mine gas drainage pipes; power plant desulfurization and dust removal pipes;


  (2) Sealing of municipal water supply and drainage pipes;


  (3) All kinds of process pipeline sealing (petroleum, chemical industry, metallurgy, papermaking, sewage, seawater desalination, food brewing and beverage processing, medicine, etc.);


  (4) Sealing of sewage collection and transportation pipelines and reclaimed water pipelines;


  (5) Sealing of drinking water delivery trunk pipes and water distribution pipes;


  (6) Oilfield water injection pipe sealing;


  (7) The hot water delivery pipe and hot spring water delivery pipe are sealed.
