Nitrile Rubber O-Ring CS 1.5mm NBR Oring Seal Sealing OD 4 - 103mm Oil Resistant

Description

Product Description:
※ Dimensions: inner diameter = outer diameter-2* wire warp (unit: mm)
※ Material: Nitrile rubber (NBR). Nitrile rubber is a copolymer of acrylonitrile and butadiene. It has excellent resistance to petroleum and non-polar solvents, as well as good mechanical properties.
The specific performance mainly depends on the content of acrylonitrile component. Those with acrylonitrile content higher than 50% have strong resistance to mineral oil and fuel, but their elasticity and permanent compression set at low temperatures become worse. Nitrile rubber has good low temperature resistance, but reduces its oil resistance at high temperatures.
※ Performance: Nitrile rubber, heat resistance 120 degrees, good oil resistance, abrasion resistance, etc.
※ Standard difference: implement standard GB1235-76, specification expression: outer diameter*wire diameter
Implement standard GB3452.1-2005, specification expression: inner diameter * wire diameter
※ Product introduction: 0” type rubber seal ring is the main seal in my country’s current rubber seal 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 In various hydraulic presses, engineering machinery, mining, metallurgy, machine tools and various hydraulic components. It plays a role of sealing under static or reciprocating motion and rotating motion.
※ Advantages:
1. Good oil resistance, water resistance, solvent resistance and high pressure oil resistance
2. Good pressure change performance, wear resistance and tensile performance
3. Used to make rubber parts for fuel tanks and lubricating oil tanks
4. Rubber parts used in fluid media such as petroleum hydraulic oil, gasoline, water, silicone grease, silicone oil, diester lubricating oil, glycol system, hydraulic oil, etc.
※ Disadvantages:
1. Not suitable for use in polar solvents, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform
2. Not resistant to ozone, weathering, heat-resistant air aging
※ Applicable medium:
1. Aliphatic hydrocarbons (butane, propane), engine oil, fuel, vegetable oil, mineral oil
2. HFA, HFB, HFC hydraulic oil
3. Normal temperature and low concentration acid, alkali, salt, water
