Expanded PTFE Seal

PTFE enveloped gaskets are used upto 150^oC and pressure upto 20Kg/Cm2 against strong acids, strong alkalis, oxygen, chlorine gas and organic solvent.

Solid flat PTFE gaskets, PTFE 'O' ring gaskets are used against strong acids, alkalis and organic solvents upto 110^oC and pressure upto 20Kg/Cm2.

Ready Cut Gaskets; from PTFE

Application: Expanded PTFE is soft and marshmallow-like, allowing it to readily conform to and seal flanges with irregular and damaged surfaces. Expanded PTFE is finding new applications in variety of industries including: Distillers; Petrochemical; Food and Beverage; Pharmaceutical; General Chemical; Power Generation; Marine, etc

Expanded PTFE joint sealant is produced by expanding 100% virgin PTFE into a highly fibrillated structure which exhibits characteristics significantly different than conventional PTFE. The expanded PTFE is much more flexible than regular PTFE and thus conforms easily to irregular and rough surfaces. In addition, the expanded material is easier to compress and exhibits excellent resistance to creep and cold flow.

Expanded PTFE

We provide customized (special) items on request;

It is often more efficient to use moulded semi - finished products to avoid excessive machining of relatively expensive materials and also to reduce machining labor and time. The tooling costs are generally very low.

(Moulded and Machined Finished Products)

PTFE Special Items

Application: Pharmaceutical, Food, Chemical Industry where a high standard of cleanliness and purity is required.

The almost universal chemical resistance, the high temperature resistance, the anti- stick, low friction surface of the PTFE Linings ensure minimum maintenance requirements, Low cost and efficient  design along with long service life makes PTFE the most ideal material for use in valve and pump diaphragms.

Size: 12 mm to 250 mm

Standard Sizes:

with Neoprene Rubber Pad

PTFE Diaphragm (for valves & pumps)

Application: Flex-O-Seal is safely used in petroleum refining companies even in their offshore operations, corrosive chemical processing, food processing, paper mill, marine installation, for glass lined or fibre glass reinforced vessels and tank lid sealing, manhole covers, vent pipes, heat exchangers, pumps or compressors housing flanges, valves and many more industrial applications where conventional pre-cut gaskets are not readily   available or unsuitable.

Flex-O-Seal is a unique sealing material manufactured from special grade of expanded 100% pure PTFE by transforming the fibrous structure by means of a special process. Though very tough, it is spongy and suited to almost all flanges, covers and narrow cavities; its special soft and flexible character enables it to be the most ideal seal under pressure without significant cold flow even on irregular, badly damaged or corroded flange surfaces. Once bolted this gasket rarely need to be retorqued

Spool length: 5 to 30 mtrs

Thickness: 1.5 mm to 100 mm

Gasket width: 3 mm to 25 mm

PTFE Flex-O-Seal

PTFE Rope Gasket is a specially formulated sealing material that withstands vibration, wide operating temperature range and has extremely low coefficient of friction. The friction free characteristic promotes smoother action and increases the life of the gasket many times over. It is used as a gasket on flanged connections, pressure vessels and all other similar mating faces as well packing for valves and similar gland applications.
