4 Benefits

Widely used in various fields of industry
Metal the cylindrical seal ring installed in the bore particularly strong and precise, the cylindrical sealing low viscosity and gases.
Dust Vice lip prevents light to moderate dust and dirt intrusion (only B1USL, B1SL of type)
Installation quit sealant is recommended in the outer coating.
