PTFE sealants and tapes
Features
Sealant tape made of 100 % virgin,
expanded PTFE manufactured by a special
process giving the tape a multi-directional
fiber structure with a self-adhesive strip
on one side. EagleBurgmann Quick-Seal
MB4 is currently the first and only multi-
directional ePTFE tape with approval and
certification according to TRD 401/VdTÜV-
Instruction Seal 100 and is especially
adapted to the needs of inspection hole
and manhole connections.
Features
These safety-gasket rings made from
multi-directional expanded PTFE are
manufactured to meet the requirements of
end-users for safety, tightness and reliability.
This gasket is especially designed for use
as handholes, headholes, manholes and
all kind of inspection ports in vessels and
boilers. According to Germany’s law an
approval according to TRD 401/VdTÜV-
Instruction Seal 100 is available.
Advantages
The manufacturing process enhances
characteristics like extremely low
compressive creep or increase in width
even under extreme conditions.
Additionally to its wide thermal and
chemical application range, the tape
shows outstanding sealability for cold
water testing and during normal operating
conditions. The tape is ideal for plant
standardization.
Advantages
This gasket material made from 100 %
virgin and expanded PTFE is free from
deterioration and physiologically harmless.
Universally applicable, these gaskets have
high adaptability and operating safety
meeting test category

Notes
No danger of confusion because one tape
could be used for all types of vessels and
lids. With the self-adhesive strip on one
side, the tape is easy to install. To get a
seal, the tape should be cut with an angle
at one end. If possible start at bolt hole.
Then the tape can be stuck around the
flange in the middle of the sealing surface.
To close the ends, the tape should again
be cut with an angle and overlapped with
the start point.
Notes
The very high adaptability during
installation ensures exceptional cold water
tightness. The previously needed high
installation effort when using a rubber
or fiber-based gasket for the cold water
pressure test is no longer necessary.
