1.Description of gasket :
Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

2.Features of gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.

4.Specifications of the gasket:
• We value every customer and every order be it one piece or thousands.
• To get more details and any questions, please feel free to contact us. We are always ready to provide you the quality service.
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.FAQ
Ask 1: Why some supplier give me the price much cheaper than you?
Answer:1.They wanna attract your attention,while you contact with them,they would raise the price by any reason.
               2.They willn't provide the high qualities to you cause it had the cheap price.
Ask 2:What the MOQ?
Answer:The MOQ should reach 800 kilograms
Ask 3:Should i pay for it If some product need molds?
Answer:I'm afraid you should pay for it,However,We would return it back when we get the first order.
Ask 4:What's the delivery circle times ?
Answer:About 2 weeks and we would give the accurate time when we know the quantity.
Ask 5:What's the FOB port?
Anser:Our port are Shanghai and Ningbo usual.

Q:What are the reasons for rubber cracking after shock absorption of rubber products?
The rubber itself is poor in tearing and its products are overloaded.
Q:What's the difference between silicone rubber and 703.704 glue?
704, temperature range of -50-250, better temperature effect, mainly used for sealing electric heating devices; electric plug sealing; instrument, instrument bonding and sealing.
Q:What are the causes of the rubber products breach?
It's aging of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value.
Q:Classification of other rubber sheets of wear-resistant rubber plates
The wear-resistant rubber sheet used in industry is divided into flat wear-resistant plywood, rhombus wear-resistant plywood and ceramic wear-resistant plywood according to the different types of rubber sheets. At present, a new type of RIT wear-resistant rubber sheet with semi vulcanized layer and chemical reaction with cold vulcanizing glue is more commonly used.As with other wear-resistant plywood, RIT wear-resistant rubber sheet is also divided into RIT flat wear-resistant plywood, RIT Ling wear-resistant plywood and RIT ceramic wear-resistant plywood.
Q:What's rubber skin?
Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.
Q:Aging of rubber parts for automobiles
Automobile rubber parts aging factors are: oxygen, ozone, heat, light, mechanical stress, moisture, oil, other chemicals or radiation, etc.. Attention should be paid to water and oil here:The alternate action of high temperature and oxygen 1. long-term water and in the external environment under the accelerated aging of rubber;2., the oil will penetrate the rubber, so that swelling occurs, rubber performance will be reduced. Therefore, trucks should avoid shock absorption of rubber bushings, oil and diesel in various occasions, including maintenance.
Q:Rubber and metal have to be sealed before they are too strong
The percentage difference between the first compression compression = original section diameter minus the trench size divided by the original O ring diameter O-ring compression is mainly depends on the material hardness and O-ring, O-ring if the hardness is 70 degrees, then the O-ring compression is equal to 20%. Of course, the lower the hardness of the O-ring, O-ring compression is greater, mainly used for low pressure places. Then the O-ring hardness increases the amount of compression of the O-ring is smaller, mainly used for high pressure, pressure resistance, resistance of small environment. And so on, the amount of compression can be any hardness O-ring you need.
Q:Which kind of rubber has the best wear resistance?
Three yuan ethylene propylene rubber introducedThree yuan ethylene propylene rubber is ethylene, propylene and non conjugated diene three yuan copolymer, began commercial production in 1963. The consumption of the whole world is 800 thousand tons every year. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Because three yuan ethylene propylene rubber belongs to polyolefin family, it has excellent curing property. Of all rubbers, EPDM has the lowest specific gravity. It absorbs large amounts of fillers and oils and has little effect on properties. Therefore, rubber compounds with low cost can be made.Viton (fluorocarbon rubber) is a synthetic rubber containing fluorine, fluorocarbon rubber high temperature resistance, oil resistance and various chemical erosion characteristics, is the science and technology of modern aviation, missiles, rockets, space navigation and so on the tip of indispensable material. In recent years, along with the automobile industry on the reliability and safety requirements continue to improve, the amount of fluorocarbon rubber in cars is also growing rapidly.
Q:There is a crack in rubber products
I personally think and vacuum should be given no relationship, if it is the bubble, and vacuum will have relationship
Q:How to make white rubber products do not yellow or delay yellowing time?
Then aging is divided into thermal aging, oxygen aging, ozone (electrostatic belongs to ozone, because static electricity produces ozone). Gas corrosion aging, heavy metals, oxidation aging. Reaction aging. UV aging and so on.
