To be successful in its duty and to attain the objective of successful sealing and trouble free operation the gland packing must have the following properties. Anti-friction properties. The gland packing basically rubs along the shaft and stationary along the stuffing box side. If the gland packing has friction it would score the shaft or the shaft sleeve and also would heat up and fail and even burn due to consistent overheating. Chemical resistance to the fluid being contai

Gland packing is used extensively for the sealing and restriction of leakage of the working fluid along the stem in valves and along the shaft in the case of pumps and also for stationary duties like manhole cover sealing. The technology has developed over a period of time. Orginally old ropes and natural fiber products were used for sealing ... with varying degrees of success. The technology has now progressed to such an extent that now several combinations of artificial fib
