Supa Maxi™ end cap - universal & tensile - A2 bolts / A4 nuts for gas -10°C to +60°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 PN 10. 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.| Variant 634/70-004 | |

| Connection: | Supa Maxi™ Coupling |
| Material: | Ductile Iron |
| DN: | DN50 - DN300 |
| PN: | PN10 |
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 gunmetal for PE/PVC and of hardened stainless steel for cast iron/ductile iron/steel pipes. For PE pipes a support bush is to be used.
- Metal grip segments are mounted with pins for maximum durability
- ±4° angular deflection at max. 1.5 x PN 10
- Large tolerance ranges
- All DNs are for PN 10
- 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 NBR rubber approved by Gastec
- Bolts of A2 and nuts of A4 are anti-friction coated to prevent galling
- Permanent protection cap protects the coupling during handling and installation. They are yellow to indicate gas.
- The pipe will not move inwards when tightening
- 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
- Working pressure max. 10 bar. Max. test pressure according to pipe standard
