The SL, which is made of chromium plated brass, is designed for the implementation of
compressed pure gases such as:
- neutral (inert) gases :
- combustible gases :
- oxidising gases :
Carbon monoxide excepted ( CO )
The SI, which is made of stainless steel, is designed for the implementation of extremely pure or
slightly corrosive gases except for HCl and chlorine.
