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
