2.1 Characteristics and scope
The GASPEX MULTI system consists of multilay-
er PEX/AL /PEX pipes and pressfittings fittings,
equipment and tools suitable for the installation.
The system of multilayer metal-plastic piping and
press-fitted GASPEX MULTI connectors conforms
with and is certified according to:
ISO 17484:2014 - Plastic piping systems -- Multilayer
pipe systems for indoor gas installations with a ma-
ximum operating pressure up to and including 5 bar
(500 kPa).
Beside the version with GASPEX "UV PROTECTED"
pipe, is certified according to:
ISO 18225:2012 - Plastic piping systems -- Multilayer
piping systems for outdoor gas installations --
Specifications for systems.
GASPEX MULTI pipes are provided nude, in rolls and
in bars, and covered with a yellow-coloured corruga-
ted polymer sheath. This last item is also supplied as
an accessory. Available sizes: 16, 20, 26 e 32.
The equipment and tools needed for installation are
common with the EMMETI GERPEX and GERPEX RA
sanitary hot water systems.
GASPEX MULTI pipes must be used exclusively
with its relative fittings and equipment.
WARNING!
The installation and testing of gas distribution net-
works composed of GASPEX MULTI system must be
done according to the local laws and regulations in
force in the country where the plant is located, as
well as these operations must be carried out by staff
in possession of the certificates /thechnical skills re-
quired by the laws and regulations in force.
2.2 Storage
Pipes and fittings should be kept in their original
packaging, protected from sunlight, from sources of
heat, frost and from contact with sharp and/or poin-
ted objects.

3.2 Fitting pressure loss
The localized load losses of fittings can be calculated
with the following formula, noting the loss coefficients
ξof individual items:
Δp = ξρv²/2
Δp = load loss (Pa = 0.01 mbar)
ξ= load loss coefficient
ρ = fluid density (kg/m³)
v = fluid speed (m/s)

3.3 Equipment
Hydraulic press-fitting tool and callipers (jaws)
Follow instructions in the manual carefully when
using the hydraulic press-fitting tools. The suitable
jaws are contour B/KSP1 or TH/ KSP11, as written
on fittings sleeve. For a correct operation, the jaw
profile must not be damaged in the area of contact
with sleeve. Make sure that the size of the jaw cor-
responds to the diameter of the fitting to be pressed.
Warning!
The use of callipers with a smaller diame-
ter than the connector being press-fitted will
damage the callipers and compromise the join
of the press-fitted connector.
NO
Calibrator / Countersink
Verify that the calibrator doesn't have any dents and/
or deformations as it could damage the inside of the
pipe and consequently affect the correct sealing of
the O-ring seal.
SI NO
Cutter
Check that the tool and the cutter do not rotate with
respect to the handle.
If necessary, tighten the fixing bolt.
