The rubber material is nitrile rubber NBR;

The metal frame is low carbon steel.

performance：

It is widely used in various fields of industry. The metal outer circle makes the installation of the sealing ring in the cavity particularly firm and precise, but the sealing effect of the outer circle on low-viscosity medium and gas medium is limited. It is recommended to coat the outer circle without drying. type sealant, but can effectively prevent the infiltration of air-side contaminants.
