50mm to 125mm two-piece couplings EC002 utilise two socket cap set screws and nuts (M8).

150mm to 300mm couplings utilise four socket cap set screws and nuts (M8), all driven by 6mm Allen key drive.

The couplings incorporate four iron nibs on each half-piece which provide electrical continuity satisfying the requirements of IEE regulations.

The couplings are manufactured in ductile iron and incorporate an elastomer EPDM seal.

The above ground couplings are coated in a red epoxy coating.
