Production from special procession of coating rubber overlaid evenly on the on the surface of metal core.

BN2620-301

Description

BN2620-301 is a new kind of sealing material that was produced from special procession of coating rubber overlaid evenly on the surface of metal core.

 Provide excellent performance of high-temperature resistance and durability. It has a relatively long shelf life than other traditional non-metallic sealing materials.

Therefore, It was generally used in harsh environmental condition of extra pressure and ultra-temperature sealing requirement.
