Gland Packing is made of braided or woven system in a box section. The constituent materials of Gland Packing can be graphite, Acrilic, PTFE, asbestos and so on. Gland packing is used to seal and limit leaks along the stem in the valve and pump shaft. Gland packing is also used for manhole cover sealing and other stationary tasks. Gland Packing is also used to reduce working fluid leakage in rotating pumps such as centrifugal pumps and screw and gear pumps.
