Big Water Tanks is an official stockist of Hansen Products — New Zealand-made True Fit threaded fittings for plumbing, irrigation, rainwater, farm and marine water systems. The Hansen Male Hose Tail (HHT) connects a female thread to flexible pipe or hose, with a BSPT male thread on one end and a hose tail on the other, in 10 sizes from 6mm (1/8") up to 80mm (3"). Reducing Male Hose Tails (HRHT) put a smaller hose tail on an 8mm (1/4") or 10mm (3/8") thread.
A male hose tail is the simplest way to connect flexible pipe or hose to a female thread, for example to run a hose from a tank outlet, pump, valve or female threaded fitting. Hansen describes the male hose tail as "used for connecting female threads to flexible pipe and hose. Push on hose and use a hose clip to hold hose on. BSPT x Hose." The Hansen HHT has a tapered BSPT male thread (T1), a hex for a spanner and a barbed hose tail. It is moulded in New Zealand from glass fibre reinforced nylon, is rated up to 16 bar at 20°C in sizes up to 50mm, and is part of the True Fit range tested to AS/NZS 4020:2018 for contact with drinking water. Below you will find Hansen's full dimension tables for every size we sell, the pressure and temperature ratings, how to pick the right size, and installation tips straight from Hansen.
| Thread Size | Max @ 20°C | kPa @ 20°C | @ 40°C | @ 60°C |
|---|---|---|---|---|
| 6mm – 50mm (1/8" – 2") | 16 bar | 1,600 kPa | approx. 12 bar | approx. 8 bar |
| 65mm (2 1/2") | 12 bar | 1,200 kPa | approx. 9 bar | approx. 6 bar |
| 80mm – 100mm (3" – 4") | 10 bar | 1,000 kPa | approx. 7.5 bar | approx. 5 bar |
Ratings are by thread size. The 20°C figures are Hansen's published maximum working pressures. The 40°C and 60°C figures are read from Hansen's straight-line derating graph and are approximate. Ratings apply to fittings used with water only and installed to Hansen's specifications. Hansen tests its products for cold water use up to 60°C (140°F) and does not recommend use above 60°C.
Body: high quality glass fibre reinforced nylon (the AS/NZS 4020 test report lists the compound as Polyamide 6 Glass Fibre Reinforced — Durethan BKV 15F). Black, UV stabilised.
The Hansen EasyFit and True Fit range passed AS/NZS 4020:2018 testing (taste, appearance, growth of aquatic micro-organisms, cytotoxic activity, metals and organic compounds) at the Australian Water Quality Centre, report 356792, completed 7 March 2023.
The "Hansen True Fit" range of black plastic threaded fittings holds WRAS (Water Regulations Approval Scheme) approval number 251102715, valid 1 November 2025 to 30 November 2030. WRAS approval shows a fitting complies with the UK water fittings regulations for use on drinking water supplies.

Hansen sizes are nominal BSP thread sizes, not the measured diameter of the thread or hose. A "15mm" hose tail has a 1/2" BSP male thread.
The hose tail's BSPT male thread (T1) screws into a female thread of the same size, for example a 25mm (1") female outlet takes an HHT25.
Push the hose onto the tail and hold it on with a hose clip. Use the hose tail size (b) and tail length (c) in the dimension table below to check it suits your hose.
The code is simply HHT plus the thread size in mm: 25mm (1") = HHT25, 1/2" = HHT15. For a smaller hose on a 1/4" or 3/8" thread, use a reducing hose tail: HRHT plus the thread size then the hose tail size, e.g. HRHT0806 is an 8mm (1/4") thread with a 6mm hose tail.

A reducing male hose tail puts a smaller hose tail on a 1/4" or 3/8" male thread. The code is the thread size then the hose tail size: HRHT1006 is a 10mm (3/8") thread with a 6mm hose tail. Dimensions are from Hansen's HRHT drawing, in mm. Rated to 16 bar at 20°C.

Using your fittings with anything other than water? Check Hansen's chemical resistance chart for True Fit threaded fittings before you install. Pool and spa chlorine, bleach, strong acids and oxidising agents all attack the material.

View Installation GuideYou need the Hansen HHT25. It has a 1" (25mm) BSPT male thread. Hansen's drawing gives it a 35.5mm hex across flats, a 27.8mm hose tail (b), a 37mm tail length (c) and 67.5mm overall, and it is rated to 16 bar at 20°C. The code is HHT plus the thread size in mm, so 1/2" is HHT15, 2" is HHT50 and 3" is HHT80.
Hansen says to push the hose onto the tail and use a hose clip to hold the hose on.
It puts a smaller hose tail on a small male thread. HRHT0806 and HRHT0810 have an 8mm (1/4") thread with a 6mm or 10mm hose tail; HRHT1006 and HRHT1008 have a 10mm (3/8") thread with a 6mm or 8mm hose tail.
Yes. Hansen True Fit threaded fittings are made from a raw material approved for potable (drinkable) water. The range passed AS/NZS 4020:2018 testing for products in contact with drinking water (Australian Water Quality Centre report 356792, 2023), and the True Fit range holds UK WRAS approval number 251102715, valid to 30 November 2030. Hansen notes the material is suitable for domestic water, not pool or spa water.
Yes. Hansen says to use a thread sealant on all threaded connections, even though the threads are tapered. Use either a thread sealing paste or PTFE (Teflon) tape. Hansen recommends Loctite 5331. The right sealant is non-hardening, compatible with plastic, and doesn't add slipperiness that encourages over-tightening. Wrap tape clockwise when looking at the end of the male thread, starting just back from the first thread.
Hand tight plus one to two turns, and no more. Screw the fitting in by hand until it is firm, then use a spanner or pipe grip on the hex for one to two more turns. Hansen is clear on this: do not over-tighten. Hansen's handy tips video makes the same point: the aim is a good seal, not maximum tightness.
At 20°C, Hansen rates True Fit threaded fittings at 16 bar (1,600 kPa) for sizes from 6mm to 50mm and 10 bar (1,000 kPa) for 80mm to 100mm, so the HHT06 to HHT50 and all HRHT reducing hose tails are 16 bar, and the HHT80 is 10 bar. Pressure ratings fall as temperature rises. At 60°C, Hansen's graph shows about 8 bar and 5 bar respectively. The ratings apply to water only, with the fitting installed to Hansen's specifications.
No. Hansen tests its products for cold water use up to a maximum of 60°C (140°F) and does not recommend use above 60°C, because plastic expands as temperature rises. Fittings that fail above 60°C are not covered by Hansen's Limited Lifetime Warranty — so do not use them on hot water lines that run above 60°C.
Hansen male hose tails are BSPT x hose, meaning a British Standard Pipe tapered male thread. This is the standard pipe thread used in New Zealand and Australia. BSP and NPT threads have different thread angles and pitches in most sizes, so don't assume an NPT thread will seal with a BSPT fitting.
Yes. Hansen says True Fit fittings can be used with metal fittings. Use a plastic-compatible thread sealant, tighten to hand tight plus one to two turns, and make sure all pipework is properly supported so the nylon fitting is not carrying the weight of metal pipe or valves.
No. Hansen advises that the high chlorine concentrations in pool and spa water will attack the fitting material. True Fit fittings are only suitable for domestic water, and fittings used on pools or spas are not covered by Hansen's Limited Lifetime Warranty. Their chemical resistance chart also rates bleach, halogens and oxidising agents as bad. See our Hansen chemical compatibility page.
Hansen True Fit fittings are suitable for use above or below ground. However, Hansen does not recommend using any True Fit fittings under driveways, paths or foundations. All pipework must be adequately supported.
