2. Armaflex on new
piping: the slip-on
method
The slip-on method is used when
you can insulate new piping
before it goes up or while it’s
being connected.
1. All you do is slip the pipe insu-
lation over the pipe or copper
tubing. The inside surface of
Armaflex Pipe Insulation is
coated with a powdered lubri-
cant, making it easy to slip the
insulation over the pipe.
(note: Small amounts of powdered
lubricant may enter open ends of pipe
or tubing. This dust must be kept out of
refrigeration systems. Plug open ends of
pipe before slipping on Armaflex Pipe
Insulation.)
2. Since Armaflex tubing is flexi-
ble, it will follow bends in tub-
ing and can be slipped right
over bent tubing, 45° sweat
ells, and couplings.
3. At 90° sweat ells, cut the insu-
lation, and butt against each
side of the fitting. A fitting
cover will be installed later
over these fittings. See
Section 4 on page 7,
Fabricating Fitting Covers.
4. Use a length of Armaflex as
long as or slightly longer than
the section of piping to be cov-
ered. NEVER STRETCH
ARMAFLEX.
5. Apply brush coating of 520 or
520 BLV Adhesive to both butt
ends to be joined, since this is
a contact-type adhesive.
6. Allow the adhesive to set until
dry to the touch but tacky
under slight pressure before
joining surfaces.
