The flexible graphite ring is made of graphite and uses a different density and taper of the intermediate ring to maintain a high degree of radial expansion at lower loads. This packing also provides lower stem friction (than square The cross-section of the ring is 25% less); it can be sealed for a long time without constant compression; the height is adaptable and the leakage is less than 500ppm. To prevent the expanded graphite packing from escaping during installation, it is recommended to use a carbon fiber reinforced graphite packing that is resistant to escape. The number of graphite packing rings is selected according to the stem diameter
