AVK Supa® is a range of universal straight couplings, step couplings and flange adaptors for cast iron, ductile iron, steel, uPVC and asbestos cement pipes. Supa® couplings are easy to mount due to the anti-friction coated bolts and nuts and the possibility of up to 4° angular deflection. The stainless steel bolts and nuts and the high quality coating offer a durable corrosion protection.
