Supa Maxi™ straight coupling - universal/non tensile - A2 bolts/A4 nuts for drinking water and neutral liquids -10°C to +70°C
AVK’s Supa Maxi™ range of universal non-tensile couplings sets a new standard. The patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket on all pipe types up to 16 bar. Supa Maxi™ couplings are very easy to mount with the possibility of ±4° angular deflection, the permanent protection caps, the lifting eye and the fact that they are tightened from the sleeve side with no need for re-tightening the bolts. NB: Not recommended for PE pipes, use tensile version instead.
