Product category


I. classification


1. O-type sealing ring series

With fluorine rubber, butyronitrile, silica gel, a variety of materials such as ethylene propylene rubber, fluorine rubber products, widely used in all kinds of machinery, all kinds of petroleum base oil and various chemical medium resistance: don't use analysing can satisfy to 60 ℃ to + 200 ℃ (double fluoro rubber FFKM after vulcanization in a certain way can reach more than 300 degrees), the temperature of the area, using the pressure range: < 10 mpa (hydraulic), < 1 mpa (pneumatic) < 16 mpa (static seal) butyronitrile and gasoline resistance (90,93,97) inflation rate is 0.


2. Y-type sealing ring

It is widely used in hydraulic, mechanical, pneumatic and other industries. Kind of petroleum base oil has excellent abrasion resistance, resistance to choose different analysing can satisfy to 60 ℃ to + 200 ℃ temperature area.


3.V seal ring

The utility model relates to an elastic rubber seal ring with axial action, which is used as a non-pressure seal for a rotating shaft. The sealing lip has the better activity and the adaptability, may compensate the big tolerance and the Angle deviation, may prevent the internal grease or the oil liquid leakage outward, also may prevent the outside splashing water or the dust invasion.


4. Use YX type sealing ring for the hole

Application: used for sealing piston in reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinder, hydraulic cylinder of general equipment. CPU: hydraulic cylinder, high temperature and high pressure oil cylinder for construction machinery. Material: polyurethane TPU, CPU, rubber product hardness: HS85 plus or minus 2 ° A working temperature: TPU: - 40 ~ + 80 ℃ CPU: - 40 ~ + 120 ℃ with pressure: 32 mpa working medium or less: hydraulic oil, the emulsion


5. Baffle ring for YX type hole

Simply described product use: this standard is suitable for the cylinder pressure is greater than 16 mpa when used with YX type sealing ring, or eccentric cylinder force, the role of protecting seal. Working temperature: - 40 ~ + 100 ℃ working medium: hydraulic oil, emulsion, hardness of aquatic products: HS92 + / - 5 a material: teflon


Two, according to the material points


3. Silicone rubber series

Equipped with advanced testing equipment, clean clean workshop. Products are widely used in electronics, medical devices, food and other industries.Analysing a variety of domestic and imported silica gel, using temperature can meet to 60 ° - + 200 ° C, the product can meet the resistance to oil, steam, medical, edible transparent, high strength, flame retardant, conductive silicone rubber, etc.


4. Fluorine rubber series products

Widely used in automobile, shipbuilding, war industry, electronic appliances and other industries, working temperature 40 ℃ to + 200 ℃, can fuel oil resistant, high temperature resistant, freon, resistance to hot water, steam and excellent chemical corrosion resistance, welcome the masses of customers to choose custom.


5. Ptfe series products

Ptfe gasket has high temperature resistance, corrosion resistance, even under high temperature and concentrated acid, alkali or strong oxidant also does not have the effect, it has been widely used as a sealing material, suitable for pipelines, flanges, reaction vessels, valves and containers on the sealing device. Special shaped parts are produced according to user's design drawings.


6. All kinds of heteromorphic miscellaneous parts

Material selection nitrile butadiene, natural, fluorine rubber, silicone, etc., widely used in automobiles, machinery, valves and other industries, choose different analysing can satisfy to 50 ℃ to + 200 ℃ temperature area. The product is wear-resisting and flexible, and can be designed according to the requirement.


7. Metal rubber sealing ring

For the metal rubber material, it is a kind of homogeneous elastic porous material, which not only have the rubber elasticity, but also has excellent characteristics of metal, can work - 150 ~ 800 ℃ temperature. At the same time, can also pressure, in a certain range with the pressure and sealing of the dual role. Its purpose:


(1) fiberglass pipe; FRP sand pipe; Glass reinforced plastic pipe jacking; Cable protection pipe; Flue gas desulfurization pipe; Coal mine gas drainage pipe; Desulfurization and dust removal pipe of power plant;

(2) municipal water supply and drainage pipeline sealing;

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

(4) sealing of sewage collection and conveying pipelines and water pipelines;

(5) sealing of main pipes and distribution pipes of drinking water;

(6) sealing of oilfield water injection pipe;

(7) sealing of hot water conveying pipe and hot spring water conveying pipe.


Features and materials

Used for installation in various mechanical equipment, in the specified temperature and pressure and different liquids and gases, in the static or movement of the sealing role


Material analysis of rubber sealing ring [1]

(1) : fluorine rubber has high temperature resistance, can be in - 30 ℃ to + 250 ℃ environment, strong oxidant, oil resistant, resistant to acid and alkali resistance. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Due to various excellent properties, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.


(2) silicone rubber: has outstanding resistance to high and low temperature performance, in - 70 ℃ to + 260 ℃ temperature range to maintain good flexibility, and has the advantages of resistance to ozone, weather aging, appropriate for the thermal mechanical seal gasket. Because there is no toxicity can be made insulation, insulation products and medical rubber products.


3, nitrile butadiene rubber: with excellent oil resistance and aromatic solvents and other properties, but not resistant to ketone, ester and chlorinated by the medium, so oil resistant sealing products to use nitrile butadiene rubber.


4, neoprene: has good oil resistance, solvent resistance, chemical media and other properties, but not resistant to aromatic oil, which is characterized by weather aging and ozone aging properties. Chloroprene rubber is usually used in the production of doors and Windows sealing strips and diaphragm and general vacuum sealing products;


5, epdm: with good temperature resistance, weather resistance aging and ozone aging performance, usually doors and Windows sealing strip, the most widely used in the automotive industry.


6, ptfe composite gasket is based on ptfe and high-quality full into the rubber material, the use of special manufacturing process and become a new type of sealing material, it integrated the excellent characteristics of teflon and rubber, make the product possesses excellent corrosion resistance, and high temperature resistance, non-toxic, viscous resistance, but also has good elasticity and tightness.
