Supa Maxi™ stepped coupling, universal tensile connection with A4 fasteners and EPDM seals, 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 full tensile strength on all pipe types up to PN16. 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.

|---|---|
| Connection: | Supa Maxi™ Coupling |
| Material: | Ductile Iron |
| DN: | DN50 - DN300 |
| PN: | PN16 |
Features
- Patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket even at minimum pipe size
- Full tensile strength on all pipes is ensured by two different metal grip segments - every other of brass for PE/PVC and of hardened stainless steel for cast iron/ductile iron/steel/stainless steel/GRP/asbestos cement pipes. For PE pipes a support bush is to be used.
- ±4° angular deflection on each side
- Large tolerance ranges
- Ductile iron body and bracket of cast steel, fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
- Gasket of drinking water approved EPDM rubber
- Bolts and nuts of acid-resistant stainless steel 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 DN 100-300
