Aramid & PTFE Graphite Combination Packing (MI-3906)

Aramid & PTFE Graphite Combination Packing (MI-3906)

By Fluid Sealing Asbestos & Non Asbestos Gland Packing

MI-3906 is a high performance Combination Packing of Aramid Fiber Yarn at the corners & Expanded PTFE Graphite solid yarn at the faces having core of Aramid yarn. The Aramid yarn is impregnated with highly anti-frictional Fluoropolymer dispersion and special break-in-lubricant. This packing is ideal for services where chemical resistance, high strength & sliding properties are essential. The special Aramid Fiber at the corners enhances pressure & extrusion resistance of the packing even in reciprocating equipments such as plunger pumps. The PTFE Graphite Yarns at the faces facilitates low friction for shafts due to its inherent characteristic of heat dissipation and ensures cooler shaft run.


Also Available : This packing can also be made available with a core of Pure PTFE Graphite Yarn instead of Aramid Yarn Core for more resiliency and cost effectiveness.

SERVICE MEDIA & APPLICATIONS Suitable to be used in Plunger & Centrifugal Pumps, Agitators, Digesters, Reactors, Autoclaves & Booster Pumps handling Ammonia & Carbonate solution, Liquor Pumps in Paper Mills like Black & White Liquor, Sewage Water, Fine Slurry Pumps, Industrial Water, Oils, Greases, Weak Acids & Alkali Solutions, Trisodium Phosphates, Sodium Hexametaphosphate, Emulsion etc.
TEMPERATURE -200 C to +280 C
PRESSURE Static - 500 bar Dynamic - 300 bar
PH RANGE 1 to 13



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.
