Oil seals are typically made from high-quality materials such as synthetic rubber, polytetrafluoroethylene (PTFE), or metals like stainless steel. These materials are chosen for their ability to withstand the harsh environments where oil seals are commonly used. For instance, a rubber oil seal might comprise 20% synthetic rubber, imbuing it with the necessary flexibility and resilience to form a tight barrier against oil. Meanwhile, a metal oil seal could consist of 30% stainless steel to provide strength and durability.
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.

In situations where the shaft has splines or an integral gear on the end, you’ll want to take precautions. These gears and splines often have very sharp edges that are quite detrimental to the seal’s integrity. You may use an installation sleeve that will allow the seal to slide past these hazards undamaged.
By far, nitrile is the most popularly used, but buyers who need seals for applications involving high-speed shaft rotation increased interest. Viton is another alternative for silicone and poly-acrylic because it’s more resistant to harmful chemicals and abrasion and works better in higher temperatures.
