Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
What Are Oil Seals?

Where loads are light, the outer skin layer can be made of silicone. It can be made of Fluroelastomer (orViton) to protect under high temperatures (more than 120 degrees Celcius). The skin can also be made of Poly Acrylate or Polytetra-FluroEthylene.

An oil seal, also known as a shaft seal or dirt seal, prevents lubricants such as oil and grease from escaping along a rotating shaft. Oil seals are an important component in preventing leaks and contaminants from clogging various engines, pumps, and pipelines.
Installing and replacing oil seals can be a daunting task. But with the right knowledge, the results can be good. Here are 8 tips to guide you on what to look for when working with oil seals. Read on for more information.
