Supply of large-size rubber sealing ring Type rubber ring is a rubber ring with a circular cross-section. Because its cross-section is shaped, it is called a shaped rubber ring. It is the most widely used type of hydraulic and pneumatic transmission systems. It is usually called in Taiwanese and Japanese companies.
Introduction to Type Rubber Ring
Type Rubber Ring is an annular rubber ring with a circular cross-section. It is mainly used for mechanical parts to prevent the leakage of liquid and gas media under static conditions. In some cases, it can also It is used as a dynamic sealing element for axial reciprocating motion and low-speed rotation. According to different conditions, different materials can be selected to suit the type of rubber ring. Usually, when selecting, try to use a ring with a large cross-section. In the case of the same gap, type rubber rings The volume of the circle squeezed into the gap should be less than the maximum allowed value for the circle to be squeezed into the gap. For different types of fixed sealing or dynamic sealing applications, the rubber ring provides designers with an effective and economical sealing element. The ring is a double-acting sealing element. The initial radial or axial compression during installation gives the ring its own initial sealing ability. The sealing force generated by the system pressure and the initial sealing force combine to form a total sealing force, which increases as the system pressure increases. Rings play an outstanding role in static sealing situations. However, in dynamic applications, rings are often used, but they are limited by the speed and pressure at the seal.

The normal operating temperature range is ℃~℃.
(Fluorine rubber) type rubber ring
The high temperature resistance is better than that of silicone rubber, and it has excellent weather resistance, odor and itching resistance and chemical resistance, but its cold resistance is not good. It is resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, animal and vegetable oils. It can be used for sealing needs of diesel engines, fuel systems and chemical plants. Not suitable for use on ketones, low molecular weight esters and nitrate-containing mixtures. The normal operating temperature range is ℃~℃.
(Fluorosilicone rubber) type rubber ring
Its performance combines the advantages of fluorine rubber and silicone ( ) rubber, and has good temperature resistance in terms of oil resistance, solvent resistance, fuel oil resistance and high and low resistance. Resistant to itching compounds, aromatic hydrocarbon-containing solvents and chlorine-containing solvents. Can be used for aerospace and military purposes. Not suitable for exposure to ketones and brake fluid. The general operating temperature range is ℃~℃.

It has good weather resistance, odor and itching resistance, water resistance and chemical resistance. Suitable for alcohols and ketones, and can also be used for sealing high-temperature water vapor environments. Suitable for use in bathroom equipment, car radiators and car braking systems. Not suitable for food use or exposure to mineral oils. The general operating temperature range is ℃~℃.
(Neoprene) type rubber ring
Excellent resistance to sunlight and weather. It can be used with refrigerants such as dichlorodifluoromethane and ammonia, and is resistant to dilute acids and silicone grease lubricants, but it expands greatly in mineral oils with low temperatures. It is easy to crystallize and harden at low temperatures. It can be used in various environments exposed to the atmosphere, sunlight, odor and itching, as well as various flame-resistant and chemical corrosion-resistant sealing links. Not suitable for use with strong acids, nitrohydrocarbons, esters, and ketone chemicals. The general operating temperature range is ℃~℃.
