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 Sirim 11:2017.
Hansen fittings, together with high density polyethylene (HDPE) 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.

Resistance to pull out the assembled joint
The joined assembly is applied at a constant tension for 1 hour and complies with ISO 3501.
Hydrostatic pressure test
The fitting body shall withstand leakage for 1 hour an internal positive pressure of 4 times its maximum sustained working pressure which is 64 Bar. The fitting joint with HDPE pipe shall withstand without leakage for 1 hour an internal positive pressure of 24 bar, 1.5 times its maximum sustained working pressure.
Hydrostatic requirement when subjected to bending stress
When the assembly is bent to a radius of 20 times the diameter of the pipe, the joined assembly shall withstand for 1 hour without leakage an internal positive prssure of 24bar.
External pressure requirement
The joined assembly shall withstand for 1 hour without leakage, a pressure of 0.80 bar above atmospheric pressure.
Effect on water
complies to MS1583; supply of water intended for human consumption.
Opacity
the wall of the fittings shall not transmit mre than 0.2% of the visible light falling on it.
