Base Seals are an important component used to seal machines and equipment. They are usually used to prevent liquid or gas leaks and protect machines and equipment from dust, pollutants, and other external elements. Base Seals mainly include rubber seals, oil seals, mechanical seals, O-rings, U-rings, V-rings, X-rings, and other types.
Rubber seals are a type of seal widely used in various machines and equipment. They are usually made of rubber materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Rubber seals are mainly used to seal liquids or gases in machinery and equipment, such as automotive engines, water pumps, pipelines, fans, refrigeration equipment, etc.
Oil seal is a type of seal specifically used to seal lubricating oil. They are usually made of rubber and metal materials and have characteristics such as wear resistance, corrosion resistance, and high temperature resistance. Oil seals are mainly used in equipment such as automotive engines, industrial machinery, water pumps, and hydraulic systems to prevent lubricant leakage.
Mechanical seals are advanced seals used to seal machines and equipment. They are usually made of metal and ceramic materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Mechanical seals are mainly used in high-speed rotating equipment, such as centrifugal pumps, compressors, fans, centrifugal separators, etc.
O-ring is a common sealing element, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. O-ring is mainly used in fields such as automobiles, machinery, and electronic equipment.
A U-shaped ring is a sealing element with a U-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. U-rings are mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
A V-ring is a sealing element with a V-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. V-rings are mainly used in fields such as automobiles, industrial machinery, and hydraulic systems.
7. X-shaped ring
An X-ring is a sealing element with an X-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. The X-ring is mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
