PE80 Socket Fusion Reducer ecoFIT SDR11 PN10 d25-d110mm

  Datasheet (PDF) |   Product Range | Instructional Video

The Georg Fischer ecoFIT reducer is an engineered PE80 socket fusion fitting designed for secure diameter transitions in industrial thermoplastic piping networks. Engineered to SDR11 and rated for nominal working pressures up to PN10 at 20 degrees C, this reducing component spans outer diameters from d25 mm to d110 mm. It provides piping engineers and installation contractors with a robust, chemically resilient solution for process cooling, industrial effluent, water treatment, and chemical distribution lines.

Technical specifications

Each ecoFIT reducer features an integrated spigot on the larger end and an internal socket on the reduced end to enable direct, leak-tight socket fusion. Manufactured strictly according to metric dimensional standards, these components ensure optimal hydrodynamic flow across line step-downs with minimal head loss.

• Product range: metric diameters from d25 mm down to d20 mm up to d110 mm down to d90 mm
• Material classification: high-grade PE80 polyethylene
• Standard dimension ratio and pressure rating: SDR11, PN10 at 20 degrees C
• Jointing configuration: male fusion spigot to female metric fusion socket
• Dimensional envelope: overall length Lmax between 39 mm and 88 mm across the range
• Component net weight: from 0.013 kg for d25xd20 mm to 0.254 kg for d110xd90 mm

Materials and standards

Manufactured from UV-stabilized, high-density PE80 resin, the ecoFIT reducer delivers exceptional chemical resistance against acids, alkalis, and aggressive process media. The material formulation guarantees outstanding impact resistance and long-term hydrostatic strength under industrial working conditions.

The socket geometries and spigot dimensions are fully compatible with ecoFIT PE100 pipes manufactured to DIN 8074 and DIN 8075 standards. This broad compatibility allows engineers to incorporate these socket reducers directly into higher-pressure PE100 networks while maintaining consistent thermal expansion profiles and reliable fusion parameters.

Installation and jointing

Jointing is executed via standard socket fusion tooling using calibrated heating bushes and spigots. Both mating surfaces—the pipe spigot and fitting socket—must be precisely peeled, cleaned with an approved polyethylene cleaner, and heated simultaneously according to manufacturer heating tables before insertion.

Because socket fusion creates an entirely homogeneous molecular weld, the resulting joint exhibits the same structural strength and chemical durability as the parent pipe. The compact axial length facilitates clean installation in tight manifolds, valve clusters, and industrial skid assemblies without placing mechanical stress on surrounding pipe supports.
