System description

The installation system consists of high-quality NiroSan® SF press fittings with red moulded sealing rings made of FKM (fluoro- and perfluoro elastomers) and NiroSan® stainless steel system pipes according to EN 10312. 

Silicone-free stainless steel piping system

They are specially made for all applications that require silicone free components. Silicone-free moulded sealing rings are ideally suited to applications such as varnishing and painting industries.

NiroSan® SF press fittings and system pipes are individually wrapped in order to guarantee that they are completely silicone free and remain so during transport up until they are finally installed.

Certified quality

All NiroSan® SF 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 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.

Marking

NiroSan® SF system press fittings can be easily recognized by the red moulded sealing ring and the additional engraving with the letters "SF" (in the past sometimes in green print) outside.

Features

Tool compatibility and Push & Stay

+ Tool compatibility: pressable with press jaws and slings with original SA, V and M profile up to and including 54 mm

+ Push & Stay function for safe, reliable installation in every location up to and including 54 mm

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

Silicone-free sealing rings

The premium NiroSan® SF system is optimally suited for all applications that need an atmosphere free of silicone particles, such as the varnishing industry

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

Exceptional flexibility

  • All dimensions from 15 to 108 mm available
  • Reliable, permanent connection with NiroSan® stainless steel system pipes:
    • NiroSan® SF (1.4404/316L), silicon-free, TIG-welded, annealed, low carbon, high (≥ 2,3 %) molybdenum content for increased corrosion resistance. Labelled in black lettering.
  • Thread according to EN 10226 and/or ISO7/1 Typ R and R/p
