PE100/Stainless Steel 90 Degrees Transition Elbow Female Thread SDR11

  Data Sheet |   Product Range | Instructional Video

The Georg Fischer ELGEF Plus 90 degrees transition elbow combines a high-density polyethylene (PE100) electrofusion socket with a factory-integrated stainless steel female threaded transition (Rp). Engineered for demanding transition points between thermoplastic pipeline infrastructure and metallic valves, pumps, or instrumentation, this fitting provides a robust, non-detachable, and leak-tight connection. Designed to meet strict utility and industrial pipeline standards, it operates reliably under nominal pressures of 16 bar for water distribution and 10 bar for combustible gas networks.

Manufactured from virgin PE100 resin compliant with EN 12201 and EN 1555, the electrofusion socket incorporates standard 4.0 mm connector pins and integrated limited-path fusion indicators for visual weld verification. The factory-molded PE-to-stainless steel transition utilizes precision sealing technology that withstands thermal cycling, internal pressure fluctuations, and mechanical stress without compromising joint integrity. The fitting is corrosion-proof, chemically resistant against aggressive media, and fully protected against electrochemical degradation commonly occurring at metal-plastic interfaces.

Key technical specifications and functional features include:

• Nominal pressure rating: 16 bar (Water) / 10 bar (Gas) in SDR 11 standard dimension ratio.
• Materials: Virgin PE100 black polymer (RAL 9005) jointed to high-grade stainless steel female thread Rp.
• Connection interface: Electrofusion socket with 4 mm contact terminals and embedded resistance wires.
• Quality conformity: Certified according to EN 12201-3, EN 1555-3, and EN ISO 15494 standards.
• Application range: Potable water networks, natural gas utilities, industrial process piping, and cooling circuits.
