А104 heavy duty compact seal set

A104 compact piston seal set is designed to be used for heavy duty hydraulic cylinders and piston applications.

It is manufactured with cotton impregnated high specification NBR sealing ring and two POM support rings as a standard. It offers ultra-low friction, free of stick-sleep, high abrasion resistance, very good dynamic and static sealing performance and is very economical because of its long service life. 

A104 can be used safely in the mining industry, marine hydraulics, steel industry and in any high performance cyliunders. It is recommended to be used in combination with minimum one ALP guiding element, such as A251, A254, A255, A256, depending on the working conditions.
