Product description

PAM HP Flex couplings S W4 are used for connecting cast iron pipes and fittings. They withstand up to 10 bar of hydrostatic pressure for most diameters and are recommended for straight runs where the pressure can occur.

Recommended use :

• High pressure
• Industrial Wastewater
• Wastewater

Major benefits :

• PAM HP couplings withstand up to 10 bar of hydrostatic pressure for most diameters.
• The solution for large-diameter networks (>300 mm).
• Stainless steel W4 (AISI 304) couplings are recommended for overhead networks, inside or outside buildings, for a non-aggressive environment.
• For wastewater liable to contain hot oil, solvents or hydrocarbons it is recommended to use couplings equipped with specific NBR gaskets (nitrile).
