| Q1. |
To what standards are Hansen Fittings manufactured? |
| BS 5114:1975 (AMD.2 – 1987) and MS ISO 10508:2004 |
| |
| Q2. |
Are Hansen Fittings approved by the Malaysia Water Authority? |
|
Yes, we are approved by SPAN – SURUHANJAYA PERKHIDMATAN AIR NEGARA(Malaysian water authority). Certificate No. SPAN/KP/A/00077-2008 & SPAN/KP/A/00078-2008.

| Q3. |
What tests have been carried out on Hansen fittings by SIRIM? |
Test under gone and passed by the Hansen Fittings & Pipes System:
- Cyclic Pressure Shock Test
- We are the ONLY plastic fittings system for portable water in Malaysia to undergo this test. Tested at 23°C ± 2°C for 10,000 cycles of alternate internal positive pressure of 1 bar ± 0.5 bar and 15 bar ± 0.5 bar at a frequency of at least 30 pressure cycles per minute with no leak.
- Resistance To Pull Out of Assembled Joint
- Apply a constant tension on the basis when the jointed pipe is subjected to a maximum internal test pressure of 37.5 bar for 1 hour without pulling out at 20 ± 2°C.
- Hydrostatic Pressure Test
- The assembly (pipes and fittings) shall withstand without leakage for 1 hour an internal positive pressure of 3 times its maximum sustained working pressure, i.e, 37.5 bar.
- Hydrostatic Requirement When Subjected To Bending Stress
- When the assembly is bent to a radius of 20 times the diameter of the pipe, the jointed assembly shall withstand for 1 hour without leakage an internal positive pressure of 3 times its maximum sustained working pressure, i.e, 37.5 bar.
- External Pressure Requirement
- The assembly (pipes and fittings) shall withstand for 1 hour without leakage, a pressure of 0.10 bar and 0.80 bar above atmospheric pressure.
- Thermal Cycling
- For 5000 cycles each duration of 30 min ± 2 min at a constant internal pressure of 4 bar. One cycle comprises of 15 min cold water @ 20°C ± 2°C and 15 min hot water @ 90°C.
- Effect On Water
- Complies with BS 6920: Part 1 and Part 2.
- Opacity
- The wall of the fittings shall not transmit more than 0.2% of the visible light falling on it.

| Q4. |
Is it locally manufactured? |
| Yes, it is locally manufactured. The factory located in Subang 2, Selangor. |
| |
| Q5. |
What is the range of sizes available? |
| 20mm, 25mm, 32mm, 40mm & 50mm |
| |
| Q6. |
Is the size of the fitting big? Can it be buried in the wall? |
| Hansen Fittings are slim enough to be buried in walls. The external diameter of the fittings is similar to PVC/ABS fittings. |
| |
| Q7. |
What material are Hansen fittings made of? |
| It is made of Nylon 6, a high performance engineering plastic. |
| |
| Q8. |
Is it UV Stabilized? |
| Yes it is. There is no problem with the fittings being exposed to sun light. |
| |
| Q9. |
Can Hansen fittings be used for both cold and hot water systems? |
| Yes, definitely. The working temperature for nylon 6 is 110°C. For cold water systems, Hansen fittings are used with HDPE pipes, whereas for hot water systems they are used with PE-RT pipes. |
| |
| Q10. |
What is the function of the barb, nut and circlip? |
| Barb – It seals and holds the HDPE pipe in place from the inside; Nut – It clamps the pipe down onto the barb and creates a high pressure seal and also gives a permanent vice like hold on the outside of the pipe. Circlip - It prevents the nut from coming out from the fitting. Please refer to How It Works. |
| |
| Q11. |
Can I over tighten the nut when I use your fittings? |
| You cannot over tighten the nut as the circlip prevents the nut from moving further forward after a certain distance. |
| |
| Q12. |
Can the nut unscrew or loosen after being screwed onto the pipe? Can this occur when work is being carried out or when the vibrator is used during concreting? |
| No. Once the nut is screwed on firmly onto the pipe, force is required to unscrew the nut. |
| |
| Q13. |
Is it safe to adjust or rotate the body of the fitting around the pipe once it is screwed
onto the pipe? |
| Yes. The body is able to rotate about the pipe and the joint will not leak. |
| |
| Q14. |
Can the Hansen system be used for shear wall system projects? |
Yes.
|
| |
| Q15. |
If I have to remove the fittings after assembly, can I reuse them? |
| Yes, you can reuse the same fitting. |
| |
| Q16. |
Are the Hansen fittings widely available? |
| Yes, we have appointed distributors throughout Malaysia and are easily available in many hardware shops. |
| |
| Q17. |
Is it user friendly? |
| Yes, the jointing method is simple, quick and easy. No special crimping tools, solvent cement or ‘o’ rings are required. Simply the Best. Please check Hansen Fittings: How to Fit. |
