Aramid & PTFE Combination Packing (MI-3905)

Aramid & PTFE Combination Packing (MI-3905)

By Fluid Sealing Asbestos & Non Asbestos Gland Packing

MI-3905 is a Multi-yarn duplex braided Hybrid Packing having Pure Aramid Yarn Corners with Pure PTFE Yarn at faces and a core of highly resilient and high tensile Aramid Fiber. The Aramid Yarn is lubricated with highly anti-frictional Fluoropolymer dispersion and a break-in lubricant, while the PTFE faces are lubricated with high temperature resisting inert lubricant. The tough PTFE impregnated Aramid Yarns ensure corner safety & dimensional stability, allowing the packing to be used at very high pressure conditions. The strong Aramid Fiber avoids corner failures in reciprocating lunger pump. The PTFE Yarns at the running surface provides excellent chemical resistance, low coefficient of friction and virtually eliminates shaft scoring. This packing is non-toxic and is ideal for food & pharmaceutical industries.


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

SERVICE MEDIA & APPLICATIONS Suitable to be used in Pumps including Centrifugal, Reciprocating and Plunger Pumps, Mixers, Valves, Extruders, Reactors, Agitators etc. carrying Pigments, Dyestuffs, Paints, Emulsions, Synthetic Molten Materials, Fine Particle Slurries, Detergents, Tri Sodium Phosphate, Hydrazine, Sodium Hexamita Phosphate etc. Extremely durable packing to be used in High Pressure Liquid Ammonia Pumps, Urea & Carbamate Condensate pumps as found in fertilizer industry.
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.
