NiroSan® (series 9000)

The installation system consists of high-grade NiroSan® press fittings with an EPDM (=ethylene propylene dien rubber) moulded sealing ring and NiroSan® stainless steel system pipes according to EN 10312.

All NiroSan® press fittings are made from the premium stainless steel type 1.4404 / AISI 316L (for pressing components) and 1.4408 (for precision cast threaded stainless steel components). The material 1.4404 contains at least 2.3 % molybdenum, yet less carbon than the conventional type 1.4401. Thereby these materials are not only of equal value but in addition, material 1.4404 / 316L stands out on account of its considerably higher corrosion resistance.

The NiroSan® press system and its components are certified in accordance with the rules and regulations of all important European certification bodies.

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.
