Gland Packings

A gland packing is the material that is fitted inside a stuffing box between the body and shaft to provide a seal. It can be made of several different substances using several methods of construction, usually lubricated with graphite or PTFE (to suit the application) and comes in various sizes to fit different size stuffing boxes and shafts. Some will also have various reinforcements built into them to suit different applications.

It is made of softer material than the stuffing box and shaft so when you tighten the gland nut on the stuffing box it compresses the softer glanding packing material to form a seal around the shaft and inside the stuffing box.

This depends upon the usage case of your stuffing box, and the environment it operates in. Service intervals will have to be planned depending upon the environment and media it is operating in. The gland packing material will perish over time so will need to be monitored for replacement.

Remove the gland nut and pull the worn gland packing out and push the new packing in. Ensure to choose the correct packing to suit your application. Please check with the chosen product’s manufacturers as they will have specific installation procedures to suit their products to the intended applications. In general for pumps - new gland packing should be loose enough to leak upon starting and the glad nut should then be tightened slowly until the leaking stops or is acceptable and the shaft still spins relatively freely. In general for valves - seek the manufacturer for their specific torque settings or compression percentages.

Gland Packing is used in valves, pumps( both rotary and piston)
