Gas & Water Sales
Pipe coupling for drinking water and other neutral liquids including wastewater free of hydrocarbons, for PE pipes only (not PVC), max. 70°C
AVK Supa Plus™ is a range of tensile couplings, flange adaptors and end caps dedicated for PE or uPVC pipes. Supa Plus™ couplings offer great flexibility due to the combined compression gasket which enables 3.5° angular deflection in all directions and makes it easy to insert the pipe ends even in the large dimensions. The bolts are anti-friction coated steel, either stainless or galvanized 8.8 and the high quality coating offers a durable corrosion protection.
