A large number of spot O-rings, sealing rings, silicone O-rings, NBR oil resistant rings, high temperature fluororubber O-rings

  Nitrile rubber has good oil resistance, high wear resistance, good heat resistance and strong adhesion
Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly low elasticity
It can be used in air at 120 ℃ or oil at 150 ℃ for a long time
In addition, it also has good water resistance, air tightness and excellent bonding performance
It is commonly used to make oil resistant rubber products, oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hose, printing and dyeing rubber rollers, cable rubber materials, etc
it is used in automobile, aviation, petroleum, copying and other industries

Scope of application of O-ring O-ring is suitable for installation on various mechanical equipment
It plays a sealing role in static or moving state under the specified temperature, pressure and different liquid and gas media
Various types of sealing elements are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters
For the selection of applicable models of O-rings under different working conditions in various industries and the price problems under different materials and configurations, please call the 24-hour quotation hotline 13758736382 to consult the direct sales price of O-ring manufacturers in 2019
At the same time, you can provide data such as overall dimensions, groove dimensions, materials and installation dimensions

O-ring is mainly used for static seal and reciprocating seal
When used for rotary motion sealing, it is limited to low-speed rotary sealing device
The O-ring is generally installed in the groove with rectangular section on the outer circle or inner circle to seal

The O-ring still plays a good role in sealing and shock absorption in the environment of oil resistance, acid and alkali resistance, abrasion resistance, chemical erosion and so on
Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system

Advantages of O-ring O-ring has the following advantages compared with other types of sealing rings:
1
It is suitable for a variety of sealing forms: static seal and dynamic seal
It is suitable for all kinds of materials
The size and groove have been standardized and have strong interchangeability

2
It is suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)
It is suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media
Through the selection of appropriate rubber materials and appropriate formula design, it can effectively seal oil, water, air, gas and various chemical media

3
Wide temperature range (- 60 ℃ ~ + 220 ℃), and the pressure can reach 1500kg / cm2 when fixed (used together with reinforcing ring)

4
Simple design, compact structure, convenient assembly and disassembly, extremely simple O-ring section structure, self sealing effect and reliable sealing performance
Since the structure of the O-ring itself and the installation part are extremely simple and standardized, it is very easy to install and replace

5
There are many kinds of materials, which can be selected according to different fluids: nitrile rubber (NBR), fluororubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc
- low cost and small dynamic friction resistance
A large number of spot O-rings, sealing rings, silicone O-rings, NBR oil resistant rings, high temperature fluororubber O-rings
NBR: this material has a maximum temperature of 130 degrees, hardness of 50-90 degrees and complete specifications
It has good mechanical properties and is resistant to mineral based lubricating oil and grease

Fluororubber (FPM): this material has a high temperature of 240 degrees and complete specifications
It is famous for its good properties such as high temperature resistance and chemical resistance
In addition, it also has good anti-aging and anti-oxidation, and very low gas permeability (especially for real high-altitude installations)

Ethylene propylene diene monomer (EPDM): the temperature range is - 50 ° C ~ 150 ° C
It has the characteristics of hot water resistance, steam resistance, aging resistance and chemical resistance
It is suitable for hot water, steam, detergent, potassium hydroxide solution, silicone oil and grease, a variety of dilute acids and chemicals
Its ethylene glycol resistance is particularly recommended, but it is not suitable for all mineral oil products (lubricating oil, fuel)

Silica gel (SI): silicone rubber has the widest working temperature range (- 60-180 & deg; c), harmless, non-toxic and tasteless, excellent ozone aging resistance, oxygen aging resistance, light aging resistance and weather aging resistance, excellent electrical insulation performance, special surface performance, physiological inertia and high air permeability
There are also many kinds of materials, such as polyurethane rubber (PU), natural rubber (NR), butyl rubber (BU), sulfonated polyethylene (CSM), polytetrafluoroethylene (PTFE), neoprene (CR), acrylic rubber (ACR) and so on
