Malleable Iron 321W Floor Flange without hole. Floor Flange without hole is different with the flange with 4 bolt holes.The main feature of non-porous flanges is their sealing properties. Since there are no holes, non-porous flanges provide a better seal, reducing the possibility of leaks. This makes non-porous flanges very useful in certain applications where high sealing requirements are required, such as in chemical reactors, pressure vessels or vacuum systems.
