Tensile straight coupling AVK, SUPA MAXI

Tensile straight coupling AVK, SUPA MAXI

Supa Maxi™ straight coupling, universal and tensile with A2 bolts nuts for drinking water and neutral liquids -10°C to +70°C
AVK’s Supa Maxi™ range of universal tensile couplings sets a new standard. The patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket and tensile strength. Supa Maxi™ couplings are easy to install as they offer ±4° angular deflection in both ends, lifting eyes, and bolts tightened from the sleeve side with no need for retightening. The permanent protection caps protect the couplings during transport and installation.

Features

• Patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket even at minimum pipe size
• Tensile strength on all pipes is ensured by two different metal grip segments - every second of brass for PE/PVC/GRP and of hardened stainless steel for cast iron/ductile iron/steel/stainless steel/asbestos cement pipes.
• For PE pipes a support bush is to be used
• ±4° angular deflection in both ends
• Large sealing ranges
• Ductile iron sleeve and bracket of cast steel with fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
• Gasket of drinking water approved EPDM rubber
• Bolts of A2 and nuts of A4 are anti-friction coated to prevent galling
• Permanent protection caps protect the coupling during handling and installation
• Large insertion depth tolerances allow for cutting the pipe slightly angled
• Bolts are tightened from the sleeve side for full access when space is limited
• Re-tightening of bolts is not necessary
• Lifting eye in DN100-800
