Hargreaves Halifax HD0001 250ml Tub of Drainage Lubricant

The Halifax HD0001 is a 250ml tub of lubricant made for use with Halifax push fit couplings, part of the Hargreaves Foundry Halifax Drain range.

How it is used

• Application - Apply a small amount to the spigot of the pipe or fitting being joined, then push it home into the coupling with firm, even pressure until the spigot meets the coupling's central register.
• Care - Avoid getting lubricant between the gasket and the coupling, or on the outside of the coupling casting, as this can make installation more difficult.
• Cure time - The lubricant stays workable for a time to allow adjustment, then dries over a period of hours, helping to hold the joint firmly once fully cured. The joint should still be adequately supported and should not be relied on to carry heavy fittings before curing.
• Rework - If an installation needs to be modified later, WD-40 can be used to help release a coupling that has been firmly secured to a pipe or fitting.

Full push fit coupling installation steps are set out in the manufacturer's Halifax Technical Guide.
