Premium Expanded Graphite Packing (MI-3910)

Premium Expanded Graphite Packing (MI-3910)

By Fluid Sealing Asbestos & Non Asbestos Gland Packing

MI-3910 is a unique interlocked braided gland packing braided from premium grade Expanded Flexible Pure Graphite Yarn and incorporating sacrificial metal corrosion inhibitor to protect the shaft from galvanic corrosion. This packing exhibits self generating lubrication that accommodates & aids self-adjustment on tightening. It shows excellent chemical resistance capability and is highly anti-frictional, hence no fear of scoring of sleeves/plungers etc. It has excellent resistant to high temperature and even shows considerable resistance to flame for a brief period. The Graphite Yarn is reinforced with a Non Metallic carrier yarn for added strength.


Also Available :

MI-3910P - Expanded Graphite Non Metallic Packing with proprietary PTFE based dispersion.

MI-3910H - Expanded Graphite Non Metallic Packing with proprietary graphite based HIGRAPH dispersion.

SERVICE MEDIA & APPLICATIONS Suitable for Dryers, Reactors, Pumps and low pressure Valves handling Acids, Alkalies, Solvents, thermic Fluid, Petrochemical, Boiler feed Water, Condensate etc.
TEMPERATURE -240 C to +650 C (+2700 C in Non Oxidizing Media)
PRESSURE Static - 100 bar. Dynamic - 35 bar.
PH RANGE 0 to 14



Gland packing is a type of sealing material used to fill the space between a rotating shaft and a stationary housing or between two mating parts in a mechanical system. It is used to prevent the leakage of fluids, gases, or other materials from the system. Gland packing works by using the pressure and friction generated by the movement of the shaft to create a seal.
In a mechanical seal, gland packing is used to fill the space between the rotating shaft and the stationary seal housing. It is used to prevent leakage of the fluid being sealed and to maintain the pressure within the system.
There are several types of Asbestos & Non Asbestos Gland Packings, including Pure PTFE Gland Packing, Pure PTFE Graphite Packing, Pure Aramid Packing, Aramid & PTFE Combination Packing, Aramid & PTFE Graphite Packing, Premium Expanded Graphite Packing, Ramie Fiber Packing etc.
To properly install gland packing in a sealing application, the packing should be lubricated and then carefully packed into the gland or seal housing. The gland should then be tightened to the appropriate torque to compress the packing and create a seal.
The main benefit of using gland packing in a sealing application is that it is a relatively simple and cost-effective way to create a seal. It is also relatively easy to install and maintain.
The choice of gland packing material can significantly affect the performance of the seal. Different materials have different properties and are suitable for different applications. For example, PTFE packing is resistant to chemicals, but for high temperatures, it may not be as durable as other materials.
