Aqualok mechanical style couplings comprise a complete range including Superfit, EasiFit, StepFit, Gripper and various others, including special couplings made to customer requirements. All mechanical style couplings are based on tried-and-tested connection principles utilising our unique, patented rubber gaskets and connector principles.

 

Aqualok SuperFit coupling optimises stockholding and simplifies installation. This is achieved by providing a tolerance range of up to 23mm in certain sizes. The Aqualok SuperFit Coupling product range includes Couplings, Stepped Couplings, Flange Adapters and other specialized fittings such as universal end caps. Products are available from sizes 50mm to 700mm. The range now also includes the Large Diameter Aqualok SuperFit Couplings. This makes Aqualok SuperFit Couplings the most complete wide tolerance coupling range available anywhere in the world. 

 

Aqualok StepFit Couplings and Flange Adapters are designed and manufactured to fit on pipes of varying nominal bore where the pipes to be connected on either side excludes the use of the Aqualok SuperFit range. Aqualok StepFit Couplings and Flange Adapters are unique in that they provide a wide tolerance facility and the unique nature of the Aqualok gasket ensures very little point pressure, negating need for a profile plate. For sizes above 600mm, dedicated Aqualok EasiFit couplings are joined to make up the required step. Special sizes of step couplings can be made to the customer’s requirements requirements.

 

Aqualok SuperFit couplings are available in a variety of reducing couplings and flange adapters to accommodate widely varying pipe sizes. Reducing couplings and flange adapters can be made to any specific customer requirements by combining our fabrication and coupling manufacturing capabilities. Customised manufacture of almost any special coupling or flange can also be undertaken to 3500mm.

 

The Aqualok SuperFit PLUS range of long barrel couplings is suited for use with HDPE pipe. A special long barrel complete with SuperFit end-rings provide ample space for pipe movement.

 

Aqualok EasiFit range of Dedicated Couplings

The Aqualok EasiFit range of Dedicated Couplings and Flange Adaptors are designed for plain ended pipes of the same outside diameter with nominal bores from 600mm to 3600 mm. The EasiFit Dedicated range is primarily used on new lay schemes and installations where the pipe size is known and the wide tolerance range of the Aqualok SuperFit coupling is not required or available. Aqualok EasiFit Dedicated Couplings and Flange Adapters can be made suitable for use with tie-bars providing full end load restraint.

Tie-bar assemblies can be adapted to facilitate pipe restraint. Fusion Bonded Epoxy coating removes the need for further on site protection .Removable central registers can be supplied for specific applications of the EasiFit Dedicated Couplings. Protective Plastic Shrinkwrap is standard on all Aqualok EasiFit Couplings.

Aqualok Repair Clamps provide a fast, economical means of repairing breaks, holes, cracks or other types of damage to steel, PVC, AC Pipes and other types of rigid pipe. This clamp comes with an overlapping gasket with moulded tapered ends that provides efficient equalised sealing on the surface of any pipe within the clamp's range. The gasket has a fine waffle surface with the resilience to easily conform to irregularities on rough pipe surfaces or in pitted areas, providing an effective seal all around the pipe. A corrosion protected armour plate spans the opening of the lugs and is bonded flush into the gasket to prevent wrinkling in the lug area, providing even gasket pressure at all points around the full circumference of the pipe. The Repair Clamp body is manufactured from high quality Stainless Steel Grade 304 or Grade 316, selected to meet the necessary corrosion resistance, flexibility and strength requirements for pressure applications.
