Supa Maxi™ transition coupling - universal & tensile with PE 100/PN 16 pipe/SDR 11 -A2 bolts/A4 nuts for water and neutral liquids to max. 20° C. Note: The maximum working temperature is set according to the ISO9080 lifetime requirements for PE pipes
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 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.

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 gunmetal 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
- 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 of A2 and nuts of acid-resistant stainless steel A4 are anti-friction coated to prevent galling
- Permanent protection cap protects 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
- A standard DVGW approved PE-pipe is pressed onto the grooved end, locked with a steel ring and sealed with a plastic shrink hose. The PE pipe end enables direct welding into PE pipes by using socket fusion or butt welding. The assembly is as minimum as strong as the PE pipe itself.
- Note: The maximum working temperature of 20°C is set according to the ISO9080 lifetime requirements for PE pipes. For higher working temperatures expect a reduction of the PE pipe’s lifetime. Please refer to the local pipe manufacturer for further information.
