" (19mm) wide tape
for fittings up to 2" (51mm)

wide tape for fittings larger
than 2" (51mm) in diameter.
2. Follow the directions under
"Instructions".
Precautions
Note. Keep Mill-Rose Blue
Monster Thread Sealing Tape
clean. Replace the clip on
the spool after use. Store in
a clean place. PTFE is virtu-
ally chemically resistant to all
media, however there are a few
exceptions. Alkali metals such
as elemental sodium, potassium
and lithium are to be avoided.
These alkali metals remove
fluorine from the polymer
molecule. Extremely potent
oxidizers such as fluorine (F
2
)
and related compounds (e.g.,
chlorine trifluoride(CIF
3
) can
be handled by PTFE, but only
with great care. Since fluorine
is absorbed into the resin, the
mixture becomes sensitive to
a source of ignition such as
impact. Other media to avoid
are 80% NaOH or KOH, metal
hydrides such as boranes (e.g.,
B
2
H
6
), aluminum chloride, am-
monia (NH
3
), certain amines
(R-NH
2
), imines (R-NH) and 70%
nitric acid at temperatures near
the suggested service level.

Instructions
Fittingsupto1½"(38mm)
diameter
1. Use ½" (12mm) wide tape.
2. Clean the male and female
threads thoroughly.
3. Wrap the tape around
the male thread.
Take care to keep
the tape under
tension as you are
wrapping so the tape
molds itself into the root
of the thread.
4. Make sure that you wrap with
the thread.
5. Make sure that the tape
does not overlap the end
of the fitting.
6. Three wraps seal most threads.
A blue color-coded, professional-density, PTFE thread sealing tape for hundreds of applications.
It creates dependable, leak-proof joints.
Note. For poor quality or damaged threads, or threads that are hard
to seal like parallel threads, or threads on fittings subject to vibration,
more than three wraps may be necessary.
