4. Advantages

Widely used in various industrial fields
Metal cylindrical bore the seal ring mounted in the cavity of the particularly strong and precise, but limited role in sealing the outer medium to low viscosity and gaseous media.
Vice-lip prevents dust mild to moderate dust and dirt intrusion
The outer coating is recommended when you quit sealant installation.
