Gas applications safely under control with Geberit Mapress
Fittings and pipes must comply with specific requirements for use in gas pipes. Geberit Mapress Copper Gas and Geberit Mapress Stainless Steel Gas have all the necessary approvals for natural gases and liquefied gases as well as for several technical gases for industrial applications.
Geberit Mapress Stainless Steel Gas & Copper Gas have been checked and certified for gas installations according to the requirements of the following testing guidelines:
Geberit Mapress Gas Fittings
Geberit fittings for gas installation are marked in yellow for clear differentiation. A yellow seal ring made of hydrogenated acrylonitrile-butadiene rubber HNBR ensures reliable sealing. Before installation the fittings are protected with a yellow protection plug and the Geberit pressing indicator also ensures additional safety on the Geberit Mapress Gas fittings as on all Geberit Mapress pressfittings.

Geberit Mapress Stainless Steal Gas is available in sizes 15-108mm, with the Gas approved yellow mark and yellow seal ring pre-fitted.
Geberit Mapress Stainless Steel system pipe 1.4401 / BS316 S 33 should always be used in conjunction with Geberit Mapress Stainless Steel Gas pressfittings for natural and liquified gases.
Geberit Mapress Stainless Steel silicone free pipe and fittings must be used for technical glases.
Geberit Mapress Stainless Steel Gas is HTB approved (PHTB, max = 5 bar) and can be laid on the wall as well as concealed in the wall.
Geberit Mapress Stainless Steel Gas is installed as an above ground pipeline within buildings (with HTB) and outside buildings (without HTB). There is no approval for installations underground
An additional protection against corrosion with concealed installations is not necessary due to stainless steel's outstanding resistance against corrosion
Geberit Mapress Copper Gas is availble for gas installations in sizes 15-54 mm, with the Gas approved yellow mark and yellow seal ring pre-fitted.. Geberit Mapress Copper Gas must be installed using copper pipes conforming to BS EN 1057 / DVGW GW 392.
The properties of the copper mean that additional corrosion protection may be necessary when laying under plaster and building materials containing gypsum, ammonia or nitrite.
Connections to commercially available gas fittings and components made from gunmetal, brass, die cast aluminium as well as ductile grey cast iron are made using pressfittings with thread or flange connections.
Geberit piping systems must not be used for the following gases:
