The Halifax HD12012 ductile iron coupling is one of the socketless, mechanically jointed Halifax system, joining 300mm Drain pipes and fittings without a traditional spigot and socket joint.
Construction
- Body - Two-piece coupling manufactured from ductile iron to BS EN 1563, finished in grey 2-part epoxy to match the below ground Halifax Drain range.
- Gasket - EPDM sealing gasket, tested aligned, at 3 degrees of deflection and under shear force in accordance with BS EN 877.
- Fixings - Secured with 4 zinc plated or stainless steel socket cap locking screws and nuts, using a 6mm Allen drive.
Electrical continuity
Where a continuous earth path matters, the HD12012 carries it across the joint via a grub screw on each side, tightened through the coating to bite into the metal beneath. Under independent testing at 25 Amps to BS EN 877:1999+A1:2006 Annex NA8, the resulting resistance came in below 4% of the standard's 0.3 ohm limit.
Hardness
BS EN 877 sets a maximum Brinell hardness value that cast iron comfortably clears, which in practice means Halifax Drain components resist accidental marking, indentation or cutting far better than PVC or HDPE alternatives, while still being straightforward to cut to length on site with the right tools.
