Premium material stainless steel

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. For this reason material no 1.4404/316L is a superior material with higher corrosion resistance than standard stainless steels.

The range encompasses all common fitting geometries such as

  • tees,
  • bends,
  • elbows,
  • flanges,
  • single and double wall plates / wall flanges,
  • couplings,
  • reducers,
  • adaptors,
  • caps,
  • unions,
  • brackets and more
Certified quality

The NiroSan® press system and its components are certified in accordance with the rules and regulations of all important national and European certification bodies such as WRAS, KIWA, DVGW and many more.

Silicone free version

All press fittings and pipes of this series are also available in a silicone free version with an EPDM O-ring (series 9000 SF). This is especially useful in industrial production which require silicone-free environments and media and ensures that no silicone is introduced by the piping system.

Features

combipress =

+ tool compatibility: pressable with press jaws and slings with original SA, V and M contour up to and including 54 mm
+ Leak path feature (certified forced leakage before pressing with EPDM and HNBR sealing rings) in combination with
+ Push & Stay function for safe, reliable installation in every position

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.

Better 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, surpassing that of conventional products.
