bend.

Apply all over adhesive coverage to one of the sur-
faces only. Once the adhesive is touch dry, fi x the
covering to the piece of tube.

below. See also the Armafl ex installation manual! The
procedure for this is the same as for Armafl ex tube.

6. Cut the fi tting piece open along the inside “throat”.
Install the fi tting piece on the pipe. Apply the appro-

For internal installations:
Cover the joints between
successive tube segments and the seam of the
throat using 30 mm wide Arma-Chek S+ Self-Adhe-
sive Tape.
For external installations:
Cover the joints
between successive tube segments and the seam of
the throat using 20 mm wide Arma-Chek S+ Butyl
Tape. Always ensure the tape is applied such that a
watershed is achieved.
Note:
In some circumstances it may be preferable to
fabricate segment fi ttings from standard, un-covered,
Armafl ex with the Arma-Chek covering applied as a sec-
ondary operation.
