Hansen Fittings

Approved by the Water Supply (Water Quality) Regulations 1989 & Water Regulations Advisory Committee (WRAS) of UK for its use in potable water, this material is superior to existing materials being used in terms of strength and ability to withstand heat. The fittings are designed and comply to British Standard BS 5114: 1975 (1981) (AMD.2 - 1987) and MS ISO 10508: 2004.

Benefits

Test results from reputed testing bodies; SIRIM, IKRAM, SPAN.

Mechanical Properties

Hansen fittings, together with high density polyethylene pipes, provide an unsurpassable potable water system. These sleek fittings are slim enough to be buried in walls and are able to withstand very high pressures.

How It Works

Push the Hansen fitting D into the polypipe E (High density polyethylene pipe) up to the circlip housing B.

Wind the nut onto the pipe a few turns by hand and tighten with a spanner until fully engaged against circlip housing B. Ridging C on the Hansen fitting has 2 functions.

It seals and holds the polypipe in place from the inside. The clamping nut A also has 2 functions. It clamps the pipe down onto the ridging C creating a high pressure seal and also gives a permanent vice like hold on the outside of the polypipe E.

It is so simple to use it is impossible to make a bad connection – Quick connect – easy to fit – there is nothing to lose with Hansen fittings.

How To Fit


Cut the polypipe square with pipe cutters, knife or saw to the required length.	Push fittings into pipe as far as possible.


Wind the nut onto pipe a few turns. Tighten with spanner or stillson.	Simply the best. No heat, crimping or solvent cement required. Leak proof. Nothing to lose.
