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 Bend (HB) changes direction in a run of low density poly pipe (LDPE) or EnduroFlex, joining two pipes of the same size, in 6 sizes from 15mm (1/2") to 50mm (2").
The HB is a 90° bend that turns a poly pipe line through a right angle, joining two pipes of the same size. Hansen describes the HB 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." It 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 bends 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.
Both ends of the HB are the same size ("pipe size x pipe size"). Hansen's sizes are nominal poly pipe sizes: 15mm = 1/2", 20mm = 3/4", 25mm = 1", 32mm = 1 1/4", 40mm = 1 1/2", 50mm = 2".

View Installation GuideThe HB joins two lengths of the same size low density poly pipe (LDPE) or EnduroFlex where the line needs to turn a 90° corner. Hansen says it can also be used to connect flexible pipe and hose.
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 Elbow (HMDE).
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.
The HB is a 90° bend with poly pipe on both ends. For a bend from poly pipe to a thread, see the Male Bend or Female Bend.
Yes. Hansen lists a spare Poly Nut in the matching size for each bend, for example the 25mm Poly Nut for the HB25.
