Assembly instructions for LK PressPex and PressPex Eco
General
All water contact parts of LK PressPex are manu-
factured from dezincification-resistant brass.
NOTE!
When installed in radiator systems, fittings
are to be protected against direct contact
with concrete since this may contain ammo-
nia residues. Therefore, use the LK Fitting
Protection or similar.
The type-approval for LK PressPex and LK
PressPex Eco applies only to joining of LK PE-X
and LK PAL Universal Pipes.
LK PressPex couplings are also type-approved
for PEM pipes in dimensions 16, 20, 25 and 32
mm with pipe dimensions according to Table 1.
The couplings must not be placed in the ground.
This range includes both PressPex couplings for
universal (gray plastic ring) and PV (red plastic
ring) which corresponds to the dimension of the
PEM pipe.

LK PressPex is designed for use in tap water, heat-
ing and cooling systems. The fitting must not be
lubricated. The installation must be carried out in
accordance with Industry Regulations Säker Vat-
teninstallation (safe water installation).
Pressure and temperature range:
• LK Press Fittings are approved for the same
pressure and temperature ranges as the LK
Universal Pipes, that is 1,0 MPa at +95ºC.
• When using a PressPex fitting with brass
flat end (EN 12164, CW602N), the flat end is
joined according to the fitting manufacturer's
instructions.
• For LK >B<Press and LK Conex, there are
clear instructions under respective product
group's assembly instructions.
