Rubber seals are materials or parts used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. The performance of various seals is affected by different factors; for example, the performance of mechanical seals (such as packing seals) is affected by temperature, medium, wear, and pressure.
According to different applications, seals can be broadly classified as follows:
By function: Shaft seals, bore seals, dust seals, guide rings, and stationary seals.
By material: Rubber, polyurethane, and engineering plastics.
