Big Water Tanks is an official stockist of Hansen Products — New Zealand-made Easy Fit poly fittings for farm, irrigation, rural water and garden pipe. The Hansen Tee Connector (HT) and Reducing Tee Connector (HRT) take a branch off a run of low density poly pipe (LDPE) or EnduroFlex, with 6 equal tees and 11 reducing tees from 15mm (1/2") to 50mm (2").
A tee connects three lengths of poly pipe, so you can run a branch line off a main line. Hansen describes the HT and HRT as "used for connecting Low Density Polyethylene Pipe (LDPE) and Enduroflex. Can also be used to connect flexible pipe and hose. Pipe Size x Pipe Size x Pipe Size." Each is a one piece fitting with no O-ring, no crimping and no solvent cement. Push the pipe onto the barbed tail and wind on the nut, and the barbs grip the inside of the pipe while the nut grips the outside. Hansen moulds the tees in New Zealand from UV stabilised glass fibre reinforced nylon, and the Easy Fit Poly range is tested to AS/NZS 4020:2018 for contact with drinking water.
All three ends are the same size, for example the HT25 is 25mm x 25mm x 25mm.
Hansen's code works like this: the first number is the "straight through" size and the second number is the "tee" (branch) size. For example the HRT2520 is 25mm straight through with a 20mm branch (25mm x 25mm x 20mm). The HRT1520 and HRT2025 have a branch larger than the run.

Body & nuts: high quality glass fibre reinforced nylon, UV stabilised. The AS/NZS 4020 test report lists the compound as Polyamide 6 Glass Fibre Reinforced (Durethan BKV 15F).
Hansen Easy Fit Poly Fittings from 15mm to 50mm have met the requirements of AS/NZS 4020:2018. The EasyFit and TrueFit range was tested at the Australian Water Quality Centre (report 356792, completed 7 March 2023).
Hansen lists the Easy Fit Poly range as fire rated UL94HB.
| Fitting Sizes | Max @ 20°C | kPa | psi |
|---|---|---|---|
| 15mm – 50mm (HT & HRT) | 16 bar | 1,600 kPa | 235 psi |
Hansen rates Easy Fit Poly fittings PN16, a maximum working pressure of 16 bar at 20°C (68°F). Hansen tests its products for cold water use up to 60°C (140°F) and does not recommend use above that. Your pipe's own pressure rating may be lower, so check the pipe table below.

Using your tees with anything other than water? Check Hansen's Easy Fit Poly chemical resistance ratings before you install. Bleach, halogens such as chlorine, strong acids and oxidising agents are rated "Bad", and pool and spa use is not covered by Hansen's warranty.

View Installation GuideThe HT and HRT connect three lengths of low density poly pipe (LDPE) or EnduroFlex, so you can take a branch off a main line. Hansen says they can also be used to connect flexible pipe and hose.
Hansen says the first number is the "straight through" size and the second number is the "tee" size. The HRT3220 is 32mm x 32mm straight through with a 20mm branch.
Hansen says to wind the nut by hand onto the pipe as tight as possible, then use a spanner or pipe grips to tighten until the nut is firm on the pipe.
New Zealand LDPE (low density polyethylene pipe), EnduroFlex, Australian Rural Class B, and Irish imperial polythene pipes, including washdown hose and non toxic tube.
Hansen designs Easy Fit Poly fittings for low density pipe. For medium density polyethylene pipe, Hansen makes its Easy Fit MD compression fittings, such as the MD Tee (HMDT) and MD Reducing Tee (HMDRT).
Yes. Hansen Easy Fit Poly fittings are made from a material approved for use with potable (drinkable) water, and fittings from 15mm to 50mm have met the requirements of AS/NZS 4020:2018 (Australian Water Quality Centre report 356792).
Hansen rates Easy Fit Poly fittings PN16, a maximum working pressure of 16 bar (1,600 kPa, 235 psi) at 20°C. Your pipe may have a lower rating; for example, Hansen's NZS 7601 LDPE table shows 0.90 MPa for 15mm pipe down to 0.35 MPa for 50mm.
Hansen tests all its products for cold water use up to a maximum of 60°C (140°F) and does not recommend use above that, as plastic expands as temperature rises. Products that fail above 60°C are not covered by Hansen's Limited Lifetime Warranty.
No. Hansen does not recommend the use of any Hansen Easy Fit fittings under any driveways, paths or foundations.
Yes. Hansen says Easy Fit Poly fittings are resistant to sea water, will not leach any substances harmful to marine life, and have provided excellent service in marine applications for many years.
No. Hansen says the high concentration of chlorine used in pool water will attack the material. The fitting material is only suitable for domestic water, and pool or spa use is not covered by Hansen's Limited Lifetime Warranty.
Yes. Hansen lists spare Poly Nuts in the matching sizes. An HT25 uses 25mm Poly Nuts; a reducing tee uses both sizes, for example the HRT2520 uses 25mm and 20mm Poly Nuts.
