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
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
Once bolted this gasket rarely need to be retorqued.
Flex-O-Seal recommended temperature - 240 C to 310 C,
Range - 0 to14
deterioration due to stocking for long time. Resistant to
high pressure, non-toxic.
recommended for use against elemental fluorine, alkali metals
and strong oxidizing agents.
Flex-O-Seal is safely used in petroleum refining
companies even in their offshore operations, corrosive
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
• The sealing surface must
be clean, free from grease and dry to enable the gasket
to stick properly.
width of the joint gasket is to be determined by the nominal
diameter or type of flange. Selection of a tentative
size of joint gasket would be approx. 1/3rd flange contact
width inside the bolt hole e.g., 7 mm gasket
to suit a 20 mm flange width.
the protective foil from the adhesive joint gasket to allow
for fitting. Stick the gasket approx 2mm away
from the bolt hole and press on lightly.
the lubricated bolts in opposite pairs. Since it is highly
compressible only bolt pressure is required
The lap joint deforms perfectly to give a reliable seal.

can be joined by cutting a step in each end
is easy to install, able to fill severe surface irregularities
and reduces inventory of ready made gaskets,
