Material and Application seals; bearing knowledge
 

NBR nitrile rubber seals: Suitable for petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricants, gasoline, water,
 
Use silicone grease, silicone and other media. It is currently the most widely used and lowest cost rubber seals. Not available for polar
 
Among solvents, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. General temperature range of -40 ~ 120 ℃.

HNBR hydrogenated nitrile rubber seals: with excellent corrosion resistance, tear resistance, and resistance to compression deformation characteristics, resistant to ozone,
 
Sun, good weather resistance. Have better abrasion resistance than nitrile rubber. It applies to washing machines, car engine system and
 
The use of new environmentally friendly refrigerant R134a refrigerant system. Not recommended for use in alcohols, esters, or aromatic solution.
 
General temperature range of -40 ~ 150 ℃.

SIL silicone rubber seals: with excellent heat, cold, ozone resistance, resistance to atmospheric aging properties. It has good insulating properties.
 
But the tensile strength than ordinary rubber difference not having oil resistance. Apply to household appliances such as electric water heaters, electric irons, microwave ovens.
 
Also applicable to all kinds of contact with the human body supplies, such as water bottles, drinking fountains and the like. Not recommended for use in most concentrated solvents, oils
 
Products, concentrated acid and sodium hydroxide. General temperature range of -55 ~ 250 ℃.

VITON fluorine rubber seals: high temperature resistance than silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance,
 
Cold is bad. For most of the oil and solvent resistance have, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and plant
 
Oils. Suitable for sealing demand of diesel engines, fuel systems and chemical plants. Not recommended for use in ketones, low molecular weight
 
Containing nitrate esters and mixtures thereof. General temperature range of -20 ~ 250 ℃.

FLS fluorosilicone rubber ring: the performance advantages of both fluorine rubber and silicone rubber, oil resistance, solvent resistance and resistance to high fuel
 
Low temperature resistance are good. Compound resistant to oxygen-containing aromatic solvents and chlorinated solvents erosion. Generally used in aviation, navigation
 
Days and military applications. Not recommended for exposure to ketones and brake oil. General temperature range of -50 ~ 200 ℃.
