Supa Maxi™ universal tensile couplings sets a new standard
Supa Maxi™ comprises a complete range of large tolerance universal and tensile couplings according to EN 14525 for water, gas and wastewater applications. Straight couplings and flange adaptors are available in DN50-600, end caps in DN50-400, and step couplings and transition couplings are available in DN50-300. Furthermore, gate valves in DN80-300 for water and wastewater applications are part of the range. The patented SupaGrip™ sealing support system features a flexible bracket, and combined with the unique grip design, it provides superior tightness and tensile resistance on all pipe dimensions and materials.

Flexible bracket with rigid metal backup
SupaGrip™ provides full support and backup of the gasket, even on minimum pipe size within the tolerance range and when used on oval pipes. The flexible bracket is designed to contract and follow the external pipe diameter. As a result, it serves as a solid backup for the gasket and enables full deflection up to 1.5 x PN test pressure.
When tightening the bolts, the bracket segments and bolts move inwards, securing that the gasket tightens around the pipe and that the grip segments grip into the pipe surface.
