MAXI Wide-Range Coupling
Join two plain-ended pipes with a MAXI mechanical coupling. The MAXI Range Coupling joins two plain-ended pipes through a coordinated compression-ring and gasket design. Its geometry is developed for broader outside-diameter coverage, giving you more scope to match compatible pipe sizes within the selected model’s range. Non-restrained connection. Not for PE pipes.
Pipe compatibility
Ductile iron, cast iron, concrete, steel, stainless steel, asbestos cement, PVC, copper, GRP and ABS. Match the measured pipe OD to the selected size range and confirm the seal and installation configuration.

How the MAXI connection works
Ring and gasket geometry
The compression ring profile and gasket cross-section work together to cover the pipe OD interval specified for each MAXI model. Check the selected row; a family maximum is not the range of every size.
Check both pipe ends
Measure each pipe OD and confirm the material against the same selected coupling. Matching nominal DN alone does not establish compatibility.
Sealing is not restraint
MAXI does not resist axial pull-out and is not for PE pipes. Where restraint is needed, review ULTRA or a pipe-specific solution.
