Data Sheet

FH Composite Pipes PEX-b

Application

Ordering

All layers are permanently bonded with each
other through a layer of adhesive.

Cross-linked Polyethylene with its raised
temperature resistance (PEX-b) is used, in
accordance with GB/T18997.1.

PEX-b pipes are of good flexibility, they can be
cold bent and curved very easily and without
special tools, saving joints and installation time.

The grey Danfoss FH composite pipe is 100%
impervious to air, temperature resistant and
highly flexible. It consists of an aluminium pipe
which is covered inside and out with a cross­linked Polyethylene layer.

Product Typ e Size Length Code no.

FH Composite PEX pipe FH-PCA 16 x 2 mm 250 m 088X0860

FH Composite PEX pipe FH-PCB 20 x 2 mm 100 m 088X0861

FH Composite PEX pipe FH-PCC 25 x 2.5 mm 50 m 088X0862

The Danfoss FH composite pipes are manufac­tured in such a way that the aluminium layer
prevents the pipe from going back to its original
form. This make the pipes easy to install.
