FAQ

Q1:How to select the correct gasket type based on my flange and operating conditions?

A: We recommend four structures, namely basic type, with inner ring, with outer ring, and with inner and outer rings, according to the flange sealing surface (convex / male-female / tongue-and-groove); at the same time, we provide material selection solutions in combination with temperature, pressure, and medium to avoid leakage caused by incorrect selection.
