## Summary description

AKA PE J-68 reduction coupling, model PE-54-504, designed to connect polyethylene (PE) pipes with diameters 50 mm and 40 mm. The fitting provides a secure transition between differing pipe sizes in water supply, irrigation, or utility networks. Suitable for use in buried or above-ground installations where a reliable, dimension-matching connection is required.

## Long description

AKA PE J-68 reduction coupling 50 x 40 mm (model PE-54-504) is a polyethylene (PE) pipe fitting designed to join pipes of different outer diameters. It enables a stable transition from a 50 mm pipe to a 40 mm pipe and is intended for water supply, irrigation systems and other utility networks where a dimension-matching, pressure-capable connection is required. The coupling is suitable for both buried and above-ground installations and is manufactured to provide a durable mechanical joint between PE pipes with minimal flow restriction.
Advantages
The reduction coupling offers a secure mechanical connection between 50 mm and 40 mm PE pipes, ensuring reliable alignment and sealing when used with compatible fusion or electrofusion methods. Its polyethylene construction provides corrosion resistance and chemical stability for long service life in common water and irrigation applications. The compact design minimizes flow turbulence at the size transition and simplifies installation in constrained spaces.
Suitable for
 Water distribution mains and branch lines
 Irrigation networks for agriculture and landscaping
 Utility piping in residential and commercial sites
 Buried and above-ground pipe installations
Key specifications
 Material: polyethylene (PE)
 Connection type: reduction coupling for direct join between two PE pipe sizes
 Compatible pipe outer diameters: 50 mm and 40 mm
 Application: potable and non-potable water supply, irrigation, general utility conduits
 Installation environment: buried or above-ground
How to use
Prepare both PE pipe ends by cutting squarely and cleaning to remove dirt, grease and oxidation. Confirm compatibility of pipe OD and wall thickness with the coupling and select the appropriate joining method (electrofusion or butt/fusion as applicable to the coupling design). Follow standard fusion procedures: align pipes centrally in the fitting, apply the specified fusion parameters and allow the joint to cool undisturbed. For mechanical or compression-based variants, follow the manufacturer's torque and sealing instructions to achieve a leak-free connection.
Usage recommendations
Before installation, verify pipe dimensions and system pressure requirements. Store the coupling protected from direct sunlight and extreme temperatures prior to use. Use certified fusion equipment and trained personnel for permanent joints; perform a pressure test on the assembled pipeline following local codes and standards.
