Product Overview

HDPE socket fusion reducing coupler for size transition. This HDPE socket fusion reducer is injection molded from PE100 resin in 20 size combinations from 25x20 to 110x90 mm, rated PN10 to PN25 under ISO 4427 and EN 12201. A smooth internal taper lets the HDPE socket fusion reducer change pipe diameter without turbulence or extra fittings.

Key Features

Smooth Bore Transition: The HDPE socket fusion reducer uses a gradual internal taper that keeps flow laminar and pressure loss low across the size change.
20 Size Combinations: One socket fusion reducer series covers 25x20 up to 110x90 mm, replacing multi-fitting step-down assemblies.
PE100 Raw Material: Each HDPE socket fusion reducer is molded from virgin PE100 resin for full pressure rating on both the large and small socket.
Leak-Free Fusion Both Ends: The socket fusion reducer welds both sockets into homogeneous joints stronger than the pipe, with no gaskets or sealants.
Corrosion and Chemical Resistance: An HDPE reducer never rusts and withstands aggressive soils, making it maintenance-free for buried service.
Compact Design: The HDPE socket fusion reducer keeps overall length short so transitions fit inside trenches, ducts and meter boxes.

Production

Raw Material

Every HDPE socket fusion reducer is molded from certified virgin PE100 resin with carbon black UV stabilizer, batch-tested for melt flow rate and density.

Molding Process

Each socket fusion reducer is injection molded with stepped core pins that form both socket diameters in one cycle, holding concentricity within 0.1 mm.

Quality Control

Batches of HDPE socket fusion reducers are sampled for hydrostatic pressure tests at 20 and 80 degrees C, concentricity checks and socket depth gauging per ISO 4427 and EN 12201.

Applications

Municipal water networks use the HDPE socket fusion reducer to step down from distribution mains to service lines.
Building water systems install this socket fusion reducer at meter connections and pump outlets of different diameters.
Agricultural irrigation relies on the HDPE socket fusion reducer to taper main lines down to lateral drip zones.
Industrial plants choose the socket fusion reducer for compact size transitions on process water piping.
