To prevent scratching or chipping, especially when your cast iron pieces are nesting within each other, use cloth or paper towels to create a buffer. Place these in between multiple pieces to prevent them from clanging together during transit.
Use a piece of wood to scrape off all traces of the old gasket from the head and cover. If total removal proves difficult, use a broad screwdriver blade, but take care not to scratch the seating.
Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.
Select the correct oil seal size


Many oil seals are capable of resisting contact with grease, fuel, water, and other elements. Knowing what type of fluid the seal will interact with will help you choose the right oil seal that can withstand those types of fluids.


In the UK, customers have a range of options for purchasing oil seals. There are several reputable UK gasket manufacturers that offer a wide selection of oil seals to meet various industrial needs.
These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.

The outer part of an oil seal is made of metal or rubber, depending on the intended application. Metal-cased seals are a cost-effective option used when the housing bore is made of the same material, allowing for equal expansion and contraction of the materials during use. Rubber-cased oil seals provide a tight fit and are commonly used when metal-cased seals have the potential to fail. They are corrosion-resistant and capable of withstanding extreme temperatures and pressures.



They are generally utilised for the following purposes:
