Rubber O-ring sealing characteristics are very good, high service life, dynamic pressure sealing work life than the basic rubber sealing products 5-10 times higher.

 

Rubber O-ring can be installed on a wide variety of mechanical equipment, under the specified temperature, pressure, and different hydraulic and acetylene gas chemicals, in situ or in motion to seal.Various types of sealed electronic devices are used in hydraulic cylinders, ships, cars, hardware, electronic components, electrical products, aerospace machinery and equipment, industrial equipment, as well as a variety of electrical instruments.Rubber O-ring is important for static sealing and continuous fitness sealing.When used for rotating motion fitness sealing, it is only limited to low-speed gear rotating sealing machine and equipment.Rubber O-type sealing ring is generally installed in the outer circle or the inner hole of the rectangular section of the pipe slot to play a sealing role.Rubber O-ring in corrosion resistance, strong oxidant, wear, analytical chemical etching and other geographical environment still has high quality sealing, shock absorption.Therefore, rubber O-ring is a wear-resistant sealing ring used in four-column hydraulic press and automatic control principle system.

 

Compared with other forms of sealing rings, O-type sealing rings have the following advantages:

 

1. Suitable for a variety of sealing methods: static data sealing, dynamic sealing, suitable for a variety of main uses of materials, specifications and trench has been standardized, strong tolerance

2. Suitable for a variety of exercise methods: rotating fitness exercise, axis and diameter repeated exercise or composition of fitness exercise (such as rotating reciprocating composition of fitness exercise)

3. Suitable for a variety of different sealing medium: oil, water, gas, organic chemical medium or other mixed medium.According to the use of suitable rubber materials and appropriate secret recipe design scheme, for oil, water, gas, liquefied gas and a variety of organic chemical medium reasonable sealing effect.The temperature application covers a wide area (-60℃~+220℃), and the working pressure reaches 1500Kg/cm2 when the application is fixed and immobile (and with the reinforcement ring).

4. The design scheme is simple, the structure is exquisite, and the installation and disassembly is convenient.O - type sealing ring cross - sectional structure of its simple, and has a self-sealing effect, sealing effect is firm.Because the O-ring itself and the location of the equipment are simple and standardized, it is easy to install and replace.

5. Many types of materials.According to the different liquid to carry out the choice: cyanide rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), neoprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), pure natural rubber (NR) and so on

6. Cheap cost

7. The dynamic friction resistance is relatively small
