Ring Type Flange Gaskets

Middle packing for flanges is a sealing material used when connecting flanges (disc-shaped parts attached to the outside of pipes to connect them). Compared to the full-surface packing, it has a smaller ring shape. It can be tightened with low pressure to prevent leaks by sealing only around the pipe. There are products made of various materials such as natural rubber, Teflon, and joint sheets. Please be aware of this when purchasing, as durability and usage will vary depending on the material.
