Transition 90 Degrees Elbow PE/Brass with Union SDR11 PN16

  Datasheet (PDF) |   Product Range | Instructional Video

The Georg Fischer ELGEF Plus 90-degree transition elbow PE/brass with union end enables secure, demountable transitions between polyethylene pipelines and threaded metallic components or mechanical equipment. Engineered for professional installers and piping engineers, this SDR 11 electrofusion fitting provides a PN16 water rating, combining robust PE100 electrofusion jointing with a versatile brass union connection.

Technical specifications

This transition elbow integrates electrofusion technology with a precision mechanical brass union to ensure leak-free performance and operational flexibility. Built for demanding utility and industrial distribution networks, the assembly guarantees optimal fluid flow with minimal hydraulic friction.

• Nominal pressure rating: PN16 (16 bar for water distribution)
• Pipe dimension compatibility: SDR 11 polyethylene pipelines
• Electrofusion interface: 4 mm connector pins with limited-path fusion indicators
• Assembly design: Integral pipe fixation on the PE socket for fast alignment
• Union connection: High-grade brass union nut supplied with a dedicated flat gasket
• Operating temperature envelope: -50°C to +60°C

Materials and standards

Manufactured from premium virgin PE100 resin and high-grade corrosion-resistant brass, this transition fitting complies with European quality and safety benchmarks. The thermoplastic body resists electrochemical corrosion and mineral scaling, while the metallic union delivers long-term mechanical reliability.

The fitting complies with the EN 12201 standard for polyethylene pressure piping systems. Its smooth inner bore prevents encrustation, keeping pressure drops negligible throughout an operational service life designed to exceed 25 years. The included flat gasket provides an airtight and watertight seal under continuous operating pressure.

Installation and jointing

Installation relies on standard electrofusion welding procedures for the polyethylene side and direct mechanical wrench tightening for the threaded brass union. The electrofusion socket incorporates integral pipe fixation to clamp pipe ends securely before welding, eliminating external clamps on these compact dimensions.

During the welding cycle, standard 4 mm connector terminals interface smoothly with electrofusion control units, while limited-path fusion indicators pop out to give clear visual confirmation of a completed joint. The brass union nut allows for fast mechanical disconnection and reassembly during scheduled valve servicing or pump maintenance without altering the welded PE pipeline.
