Hargreaves Halifax HD6095 150mm Cast Iron Grey Push Fit Drain Pipe Coupling
Unavailable for Online Ordering
Call for Availability150mm single-piece push fit coupling for joining Halifax Drain pipes and fittings with a push, rather than bolted, connection.
- Diameter - 150mm nominal bore, for joining Halifax Drain pipes and fittings.
- Material - Single-piece ductile iron casting to BS EN 1563 with two EPDM sealing gaskets.
- Fitting - Pushed home over a lubricated pipe spigot rather than bolted, for faster assembly.
- Electrical continuity - Uses the same grub screw continuity system as the Halifax ductile iron coupling.
The Halifax HD6095 is drawn from the Halifax Drain range as a 150mm single-piece push fit coupling, joining pipes and fittings with a push connection rather than the bolted assembly used by the standard ductile iron coupling.
Construction
- Body - Single-piece casting manufactured from ductile iron to BS EN 1563, finished in 2-part epoxy to match the Drain range.
- Gaskets - Two EPDM sealing gaskets, meeting the same hydrostatic test pressures as the Halifax ductile iron coupling.
Fitting
- Lubricant - Apply a small amount of Halifax push fit lubricant (HD0001) to the spigot of the pipe or fitting before pushing it home.
- Assembly - Apply firm, even pressure until the spigot abuts the coupling's central register, then support the joint while the lubricant cures.
Ground movement
Cast iron expands by around 0.01mm per metre for every degree Celsius rise in temperature, a coefficient close to that of concrete and steel. In practice this means a buried Halifax run moves very little relative to the ground around it, unlike some plastic systems where thermal expansion can be five to twenty times greater.
Full push fit installation steps are set out in the manufacturer's Halifax Technical Guide.
