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.
