Universal, MAXI and ULTRA
Choose by pipe material, measured outside diameter and whether axial restraint is required.
UNIVERSAL — Economical conventional mechanical connection. Check each model’s OD interval. Non-restrained; not for PE pipes. Coupling · Flange adaptor
MAXI — AQUAFITTING compression-ring and gasket design with model-specific OD coverage. Non-restrained; not for PE pipes. Coupling · Flange adaptor
ULTRA — Wide-range sealing and grip with axial restraint for the applicable configuration. Appropriate PE configurations are available. Coupling · Flange adaptor
Check the exact product, OD range and installation requirements before selection.
Pipe connections.
Choose the connection type.

Choose a pipe-to-pipe coupling, a pipe-to-flange adaptor or a dismantling joint. Compare the product series, measured pipe outside diameter and installation requirements.
ULTRA Wide-Range Flange Adaptor
Pipe-to-flange connection. Match the pipe-side outside-diameter range and mating flange separately.
Dismantling Joint
Flanged dismantling joint. Review PN10/16 and PN25 drawings and dimensions on one product page.
PE Flange Adaptor — Compression-Grip Series
Connect a PE pipe end to a flanged component using the Compression-Grip series.
Pipe materials: PE
Match pipe outside diameter, wall thickness / SDR and flange connection.
Quick Flange Adaptor for PE/PVC Pipes
Connect PE or PVC pipe to a flanged component with the appropriate Quick configuration.
Pipe materials: PE / PVC
PE configuration uses a brass grip; PVC configuration does not. The photograph shows the PE configuration.
Long-Body Gibault Joint for PVC Pipes — 300 mm
Gibault coupling with a 300 mm body-length designation.
Universal-to-PE Transition Coupling
PE-specific connection at one end and a separate universal OD range at the other.
ULTRA Wide-Range Coupling
Pipe-to-pipe connection. Join two plain pipe ends with the selected wide-range coupling.
PE Flange Adaptor — Lock-Ring Series
Connect a PE pipe end to a flanged component using the Lock-Ring series.
Pipe materials: PE
Select pipe outside diameter and flange drilling separately.
PE Pipe Coupling — Compression-Grip Series
Connect two PE pipe ends using the Compression-Grip series.
Pipe materials: PE
Use the Compression-Grip dimensional schedule; it is a separate design from Lock-Ring.
Quick Flange Adaptor for Ductile Iron Pipes
Connect a ductile iron pipe end to a flanged component.
Pipe materials: Ductile iron
Standard and Toothed-Grip are separate configurations. Select the required configuration.
Long-Sleeve Universal Flange Adaptor
Long-sleeve mechanical connection between a plain pipe end and a flange.
PE Pipe Coupling — Lock-Ring Series
Connect two PE pipe ends using the Lock-Ring series.
Pipe materials: PE
Check both pipe outside diameters and the installation dimensions.
Large-Diameter PE Flange Adaptor
Large-diameter flange connection, selected by the applicable pipe-specific configuration.
Bell Joint Repair Clamp for Ductile Iron Pipes
Repair clamp for compatible ductile iron socket-and-spigot joints.
Dismantling and Maintenance Access
For installations that require axial adjustment, valve removal or future maintenance access, use a dismantling joint route rather than a standard coupling. Confirm flange drilling, required adjustment range, pressure requirement and installation space before quotation.
