Shaft Seals, also known as lip seals or oil seals, are used with rotating, reciprocating and oscillating shafts to contain fluids and exclude contaminants. They are available in inch and metric dimensions and single and double lip designs. Various lip materials are available to suit design requirements such as temperature and chemical resistance. Clark Seals designs and manufacturers custom shaft seals that are perfectly matched to each application, ensuring maximum reliability and performance.
