Model: O-ring
Material: nitrile rubber
Hardness: 70--75
Product introduction: "O" type rubber sealing ring is the main seal in my country's current rubber sealing products. It has the advantages of simple structure, low price, convenient installation, small dynamic friction coefficient and reliable sealing. It is widely used in automobiles, tractors and Various hydraulic presses, construction machinery, mining, metallurgy, machine tools and various hydraulic components. It plays a sealing role in static or reciprocating motion and rotating motion.
Working medium: air, water, mineral oil, etc.
Common materials: nitrile rubber (NBR), silicone (VMQ), fluorine rubber (FKM)Performance:
1. Nitrile rubber: heat resistance of 120 degrees, good oil resistance, wear resistance, etc.
2. Silicone: heat-resistant 220 degrees, non-toxic and environmentally friendly, general oil resistance, etc.
3. Fluorine rubber: heat resistance of 200 degrees, good oil resistance, wear resistance, pressure resistance, corrosion resistance, acid and alkali resistance, etc.
shortcoming:
1.Not suitable for use in polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform
2.Not resistant to ozone, weathering, and heat-resistant air aging
Applicable media:
Aliphatic hydrocarbons (butane, propane), engine oils, fuel oils, vegetable oils, mineral oils
HFA, HFB, HFC hydraulic oil
Low-concentration acid, alkali, salt, water at room temperature
