Carbon Filament Yarn Packing (MI-3915)

Carbon Filament Yarn Packing (MI-3915)

By Fluid Sealing Asbestos & Non Asbestos Gland Packing

MI-3915 is a special packing manufactured from a High Structural Carbon Fiber Yarn. The packing is thoroughly impregnated with a custom made Graphite based HIGRAPH dispersion to act as blocking agent. The interbraid construction and the blocking agent prevent body leakage of any gaseous or liquid material. The packing is also incorporated with Molybdenum based metal corrosion inhibitors to prevent pitting of the stem. This packing has high mechanical strength & dimensional stability, low coefficient of friction, excellent resistance to chemicals and excellent heat dissipation for cooler shaft runs without wear to packing volume, thus, ensuring excellent Sealing service.


Also Available : MI-3915P - Carbon Fiber Non Metallic Packing with proprietary PTFE based dispersion.

SERVICE MEDIA & APPLICATIONS Suitable for Pumps, Valves, Agitators, Mixer, Dryers etc. handling Caustics, Acids & Alkali, Liquor, Steam, Thermic Fluid, Boiler Feed Water, Condensate, Demineralized Water, Fuel/Lube Oil, Gases, Hydrocarbons etc. Also used in Stem Tubes, Soot Blowers & Reaction Vessel.
TEMPERATURE -240 C to + 650 C
PRESSURE Static - 250 bar Dynamic - 200 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.
