Materials and processes

PP-R

Polypropylene Random (PP-R)

Base material of the pipe systems for drinking, cold and hot water installations, e.g. PIPE FIBER SDR 7.4 PP-R.

PP-RCT

PP-RCT (reinforced PP-R)

For drinking water, cooling and heating systems with increased requirements, e.g. PIPE FIBER SDR 9/11 and PIPE WEFAKLIM FIBER SDR 11.

Brass

For valve connections and pipe transitions such as PIPE UNION BRASS FEMALE.
