O-ring O-ring (O-rings) is a kind of rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring rubber sealing ring, also called an O-ring. It began to appear in the mid-19th century, when it was used as a sealing element for steam engine cylinders. O-rings are the most common mechanical design for seals because of their low cost, simplicity of manufacture, reliable function, and simple installation requirements. O-rings are subjected to pressures of tens of megapascals (kilo pounds). O-rings can be used in static applications as well as in dynamic applications where there is relative movement between components, such as shafts of rotary pumps and pistons of hydraulic cylinders.

YX O-ring for hole

Product use: used for the sealing of pistons in reciprocating hydraulic cylinders. Scope of application: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, Rubber.

Product hardness: HS85±2°A Working temperature: TPU:-40~+80℃, CPU:-40~+120℃ Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion.

Baffle O-ring for YX type hole

Product use: This standard is suitable for use with YX type sealing ring when the working pressure of the oil cylinder is greater than 16MPa, or when the oil cylinder is eccentrically stressed, it plays the role of protecting the sealing ring. Working temperature: -40~+100 degrees. Working medium: hydraulic oil, emulsion, water Product hardness: HS 92±5A Material: PTFE.

YX type O-ring for shaft

Product use: used for the sealing of piston rods in reciprocating hydraulic cylinders Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders. CPU: Hydraulic cylinders for construction machinery and oil cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, rubber Product hardness: HS85±2°A Working temperature: TPU:- 40~+80℃ CPU:-40~+120℃ Working pressure: ≤32Mpa, working medium: hydraulic oil, emulsion.

The O-ring has excellent sealing performance and long working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber sealing products, and can be up to dozens of times. Under certain conditions, it can have the same life as the sealing base.

The frictional resistance of the O-ring is small, and the dynamic and static frictional forces are equal, which is 1/2-1/4 of the frictional force of the "0"-shaped rubber ring, which can eliminate the "crawling" phenomenon of movement at low speed and low pressure.

The O-ring is highly wear-resistant, and has an automatic elastic compensation function after the sealing surface is worn.

O-ring good self-lubricating performance. Can be used for oil-free lubrication seal. O-ring

The O-ring has a simple structure and is easy to install.

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

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