All NiroSan® Gas press fittings are made of the material 1.4404 / AISI 316L (for moulded fittings) and 1.4408 (for threaded fittings and stainless steel precision castings). The material contains at a minimum of 2.3 % molybdenum and a lower carbon content than the conventional steel quality 316. For this reason material no 1.4404 / 316L is a superior material with higher corrosion resistance than standard stainless steels.
The NiroSan® Gas press system is certified by and in accordance with all important European certification bodies.
NiroSan® Gas has been tested by the DBI-Gastechnologisches Institut e.V. in Freiberg for the use of up to 100 % hydrogen. The piping system carries the “H2ready” quality mark. For the transport of H2, higher operating pressures of up to 16 bar are possible without any problems.
NiroSan® Gas press fittings with yellow moulded part seal made of HNBR are marked on the outside with a yellow “GT-PN 1 (89 mm) or GT-PN 5”.

Fast installation, no risk of fire
The connection with stainless steel pipes by cold pressing enables a fast, time-saving installation and eliminates the risk of fire during the process. NiroSan® installation systems are therefore ideally suited for renovation work.
High corrosion resistance
The premium stainless steel type 1.4404 (316L) and the exceptionally smooth, passivated surface of pipes and fittings lead to an excellent corrosion resistance.
