Dry Pure PTFE Packing (MI-3921)

Dry Pure PTFE Packing (MI-3921)

By Fluid Sealing Asbestos & Non Asbestos Gland Packing

MI-3921 is interlocked braided from Dry Pure PTFE Fiber yarn without any lubricant or additives. It ensures safety & purity of the medium with no contamination of the fluid media. It serves as an excellent packing for Oxygen & Hydrogen services. This is a self lubricating packing with very low coefficient of friction and as such safeguards the parent equipments from erosion during operation. The packing needs very little gland adjustment after initial installation and is inert to almost all known chemicals except for some Molten Alkali Metals and Aquaregia.

SERVICE MEDIA & APPLICATION Suitable for use in Liquid Oxygen Pumps & Valves, Air Compressors, Mixers, Agitators etc. handling Acids & Alkalies, Solvents, Chemical Equipment Glands, Hydrogen Services, Food & Pharma industries etc.
TEMPERATURE -200 C to +280 C
PRESSURE Static - 200 bar. Dynamic - 100 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.
