The Halifax HD8012 ductile iron coupling forms part of the socketless, mechanically jointed Halifax system, joining 200mm 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
The HD8012's grub screw pair, tightened through the coating on either side of the joint, gives metal to metal contact for electrical continuity across the coupling. Testing at 25 Amps under BS EN 877:1999+A1:2006 Annex NA8 recorded a resistance under 4% of the permitted 0.3 ohm maximum.
