DM Plastics and Steel electrofusion (EF) fittings deliver high‑integrity, permanent joints for pressured trunk mains, reticulation and critical utility networks. Available in a broad size range (typically DN25–DN630, size and style dependent), our EF couplers, tees, elbows, reducers, saddles and flange adaptors are manufactured for compatibility with PE pipe and to industry standards.
Engineered for repeatable fusion performance, EF fittings provide leak‑free, welded joins that suit civil, mining, municipal and industrial applications where long‑term integrity matters. Our products are supplied with clear welding guidance, recommended clamping practices and cool‑down information to support correct installation by qualified PE welders.
DM Plastics and Steel combines quality components, in‑house inspection and technical support with a Producing Solutions approach — helping clients specify the right EF styles, source appropriate clamps and tooling, and deliver bespoke fabricated assemblies or repair solutions to meet project specifications and timelines. Contact our team for sizing, compatibility checks and installation assistance.
Straight EF couplers for permanent, welded in-line joints on PE pressure mains and reticulation.
Equal and reducing EF tees for branching connections on pressured PE mains.
90° and 45° EF elbows for direction changes on PE pressure pipe systems.
Concentric and eccentric EF reducers for size transitions on PE pressure mains.
Long and short spigot fittings for butt fusion or compression transitions, plus EF saddles and branch outlets for tapping into existing mains.
EF flange adaptors, stub flanges and valve adaptors for tie-ins to flanged valves, meters and metallic infrastructure.
Electrofusion transition adaptors for connecting PE pipe to metal, BSP or other system types.
EF repair couplers and emergency repair fittings for rapid, permanent reinstatement of damaged mains, plus end caps and bespoke fabricated assemblies.

DM Plastics & Steel — Your poly pipe fittings partner for reliable pipelines. Through our Producing Solutions approach we partner with clients to specify the right EF styles, provide bespoke fabricated assemblies and repair solutions, and deliver technical support and documentation that reduce on‑site risk and help keep projects on schedule.
Operators installing electrofusion fittings on PE pipelines must be trained and qualified in PE welding by an accredited training organisation. A list of approved PE welding trainers is available from the Plastic Industry Pipe Association (PIPA)’s website .
Clamping the fittings during the EF joining process is important as it prevents the pipe and fittings from moving during the welding & cooling process. It also keeps the fittings aligned with the pipe, preventing the weight of the pipe from applying lateral pressure to the join.
