O-ring sealing performance is excellent, high working life, dynamic pressure seal working life than the conventional rubber sealing products 5-10 times, up to ten times, under some conditions can be the same as the sealing matrix life.

O-ring friction resistance is small, dynamic, static friction force is equal, is "0" rubber ring friction 1/2-1/4, can eliminate low speed, low pressure movement "crawling" phenomenon.

O-ring high wear resistance, sealing surface wear with automatic elastic compensation function.

Good self - lubricating performance of O-ring. It can be used as oil-free lubrication seal.

O-ring structure is simple, easy to install.

O-ring working pressure: 0-300MPa; Working speed: ≤15m/s; Operating temperature: -55-250 degrees.

O-ring suitable medium: hydraulic oil, gas, water, mud, crude oil, emulsion, water-glycol, acid.

O-ring is suitable for all kinds of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the static or moving state sealing effect. Sealing components of various types 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 all kinds of instruments and meters. O-ring is mainly used for static sealing and reciprocating sealing. For rotary motion seals, only low-speed rotary seals. O-ring is generally installed in the outer circle or the inner circle of the rectangular section of the groove to play a sealing role. O-ring in oil, acid and alkali resistance, abrasion, chemical erosion and other environments still play a good sealing, shock absorption. Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.

Compared with other types of sealing rings, O-ring has the following advantages:

-- Suitable for a variety of sealing forms: static seal, dynamic seal

-- Suitable for all kinds of materials, sizes and grooves have been standardized, strong interchangeability

-- Suitable for a variety of motion modes: rotating motion, axial reciprocating motion or combined motion (such as rotating reciprocating combined motion)

-- 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, to achieve effective sealing effect on oil, water, air, gas and various chemical media. The temperature can be used in a wide range (-60 ℃ ~ + 220 ℃), and the pressure can be up to 1500Kg/cm2 when fixed in use (with the reinforcing ring).

-- Simple design, compact structure, convenient assembly and disassembly

O - ring section structure is very simple, and has self - sealing function, sealing performance is reliable.

Because the O-ring itself and the installation part of the structure are extremely simple, and has been standardized, so installation and replacement are very easy.

-- A variety of materials

Can be selected according to different fluids: nitrile butadiene rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), neoprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc

-- Small kinetic friction resistance
