Wrapped Gasket

Product Description
The gasket specially designed for high and medium pressure flange sealing is made by interwinding a formed metal strip with a high-performance non-metallic sealing strip (Type A). Depending on the type of flange sealing surface, it is equipped with an inner reinforcing ring (Type B), an outer reinforcing ring (Type C), or both inner and outer reinforcing rings (Type D). We integrate the most advanced wrapped gasket manufacturing equipment and technology from both domestic and international sources, and have a production capacity of 10 million pieces per year.
