It is used for the transition connection of PE pipes of different diameters.
SDR11 HDPE Fittings Reducer - PE100 Diameter Transition
The SDR11 HDPE fittings reducer is an injection moulded PE100 component used to transition between PE pipes of different diameters. It is joined to the pipe by heat fusion, so the connection forms an integrated seal with joint strength higher than that of the pipe body. The result is a non-leaking, corrosion-resistant and hygienic transition that carries the full pressure rating of the line.

Key Features
- Integrated sealing - heat fusion produces a joint stronger than the pipe wall, with no gasket or mechanical fastener to fail.
- Leak-free and hygienic - non-toxic PE100 material, suitable for potable water and other sensitive media.
- Chemical resistance - unaffected by acids and alkalis, which suits chemical, gas and sewage service.
- Ageing and impact resistance - excellent low-temperature impact performance and a long service life, even when buried.
- Light and easy to install - low weight and simple fusion, which keeps installation labour down.
