This type of seal is used for heavy work and drilling operations and is used together with the guide ring. In the construction of this type of seal, polyurethane with high grades is used to achieve high anti-wear properties. NBR material is recommended for sealing at low pressure. The material used to prevent extrusion is Acetal or POM.
