Installation Guide

Installation:

Sweat fittings on
new pipe
1. Before fitting is soldered, push
the Armaflex back on the tubing,
and hold in place with
clamps applied to the tubing. To
avoid damage to the insulation,
tubing and fitting temperatures
must not exceed the upper use
limit of 220˚F. Remove clamps
after fitting has been soldered
and has cooled. Note that sweat
fittings are insulated with the
same size Armaflex as used on
the tubing.
Note: Apply clamps to tubing, not
to Armaflex. Insulate heavy
bronze fittings with fitting covers
fabricated and applied as direct-
ed under screwed-type fittings
below. The solvent in 520 and
520 BLV Adhesive is flammable,
so take precautions during sol-
dering. Always close the contain-
er tightly when not using; keep it
away from heat or sparks. (Read
the cautions on the label.)
2. Fabricate fitting cover from
properly miter-cut pieces. After
adhesive has dried, carefully
slit the fitting cover. See
Section 4 on page 7,
Fabricating Fitting Covers.
3. Snap fitting cover in place over
the fitting.
4. After the line has been
tested, apply brush coating of
520 or 520 BLV Adhesive to all
joint surfaces.
5. Allow the adhesive to dry until
dry to the touch but tacky
under slight pressure before
joining surfaces.

6. Armaflex is slipped over the
line and butted tightly against
the fitting.
7. Fabricate fitting covers from
miter-cut pieces of Armaflex.
Slit the completed cover, and
snap it in position over the fit-
ting. (Fitting cover should over-
lap the pipe insulation by at
least one inch.)
8. After the line has been tested,
complete the application by
cementing the slit joint of the
fitting cover with 520 or 520
BLV Adhesive. When adhesive
has become tacky to the
touch, press the joint firmly
together. Also, cement the 1″
overlap with 520 or 520 BLV
Adhesive by forcing the brush
between the two surfaces.
Screwed fittings on
new pipe
Insulate screwed fittings with
sleeve-type fitting covers made
up from Armaflex Pipe Insulation
having an inside diameter large
enough to overlap the insulation
on the straight piping next to the
fitting by at least 1″. See chart on
page 8 for sleeving sizes.
