- Product Description
Standard: ISO4633 GB/T21873 GB/T9119
Application: Rubber sealing gaskets for various types of flanges. Working pressure PN10/PN16
1. Waterline type flange gasket: Concentric water stop lines are evenly distributed on the two sealing surfaces of the gasket, and these water stop lines have a good sealing effect on the surface of the flange when it is concave convex, rough, or corroded.
2. Full disc flange gasket: It refers to adding a water stop line and bolt holes on top of the ordinary flange gasket. When the pressure is too high, the ordinary flange gasket is prone to displacement, while the full disc flange gasket can maximize the safety and stability of the pipeline network.
