Rubber Sealing Rings

Rubber Sealing Rings provided by Xiamen Liangju Rubber Co., Ltd. of China can be produced as annular sealing parts through mold molding using specific rubber materials according to customer requirements. At the connection points of mechanical systems, fill the gaps and utilize the elasticity of rubber to achieve a sealing effect under pressure. Xiamen Liangju Rubber offers this product to meet the personalized demands of the automotive, hydraulic, pneumatic, and home appliance industries for equipment sealing performance, durability, and specific working conditions (such as oil resistance, high-temperature resistance, and chemical corrosion resistance).

Product function

Rubber Sealing Rings is a kind of mechanical gasket with a circular cross-section. They are made of elastomer materials and are used in pumps, cylinders and other fluid applications to form a leak-proof seal between two components. It can seal the opposite surface very well. It can prevent water leakage and is not affected by corrosion and weathering. Not affected by floods; Prevent the loss of air or heat.

Feature

Different working media such as engine oil, water, hydraulic oil and chemical solvents require the matching of different rubber materials: NBR for oil resistance, FKM for high temperature resistance and VMQ for aging resistance. The structural forms of Rubber Sealing Rings are diverse, ranging from the simplest O-rings (circular cross-section), to lip rings (with lips for enhanced sealing) and star rings (used for high pressure). Each structure corresponds to different sealing pressures and motion states. Finally, its dimensional accuracy requirements are extremely high, especially the inner diameter, outer diameter and cross-sectional diameter, which must be perfectly matched with the sealing groove to achieve the best sealing effect.

Selection, installation and storage

It is essential to select the appropriate material based on the working medium and temperature. For instance, EPDM cannot be used for transporting petroleum-based media. When installing Rubber Sealing Rings, it should be ensured that the sealing groove is clean and free of burrs, and the pressure should be applied evenly to avoid scratching the sealing ring or causing the installation to be out of place
