Compression Reducing Couplers
A compression reducing coupler is a transition part with compression ends of different sizes that steps a larger PE line down to a smaller one.
It is used when stepping down from an irrigation main to distribution lines and for size changes after pump outlets. Size combinations within Ø20 – Ø63 mm are supplied depending on the model.
Main Applications
- Transition from mains to distribution lines
- Size reduction at pump outlets
- Plot inlets
- Drip irrigation supply lines
- Garden line reductions

How to Choose?
- Measure both sizesDetermine the outside diameters of both PE pipes.
- Write the combinationState it as large × small (e.g. 32 × 25).
- Choose the pressure classSelect the PN for line pressure.
- Check the flow directionThe larger size should be on the supply side.
