Technical Specifications
How tight should I tighten my fittings?

Wind nut by hand onto pipe as tight as possible. Use spanner or pipe grips to tighten until nut is firm on pipe.

I have laid my pipe and connected my joiners. I came back in the morning to find that the pipe and fittings had come apart.
When laying pipe ensure there is sufficient slack in the pipe to allow for expansion and contraction of the pipe as the ambient temperature changes.
What type of pipes will Hansen fittings connect to?
New Zealand L.D.P.E. (Low Density Polyethylene Pipe), EnduroFlex2, Australian Rural Class B, Irish Imperial Polyethylene Pipes and a variety of suction & soft Hoses for general use (including wash down hose and non toxic tube).
What is the best size of pipe for my needs?
Refer to a qualified water reticulation installer for professional advice to suit your needs.
Can I use my Hansen fittings with my swimming pool/spa pool set up?
No, as the high concentration of chlorine used in the water for pools, will attack the material. The fitting material is only suitable for use with domestic water. Hansen products that are used in this application will not be covered by warranty.
What temperature can I use Hansen fittings at?
Hansen have tested all its products for use with cold water up to a maximum temperature of 60°C (140°F). We do not recommend the use of these products with temperatures higher than 60°C (140°F) as plastic expands due to temperature increases. Hansen cannot guarantee the products will perform when used with temperatures over 60°C (140°F). Hansen products that have failed in temperatures higher than 60°C (140°F) will not be covered by warranty.
Can I use Hansen fittings in marine applications?
Yes. While marine applications vary, Hansen fittings are resistant to sea water. The fittings will not leach any substances that will be harmful to marine life. Hansen fittings have provided excellent service in marine applications for many years without failure.
