The Donsen Compression Reducing Coupler is used to join two compatible PE or HDPE pipes of different sizes in a straight line. It is ideal for reducing from a larger pipe size to a smaller pipe size in irrigation, garden water systems, agricultural water supply and general cold-water pipe installations.

The compression design allows the fitting to connect directly to PE pipe without solvent cement, heat welding or specialist fusion equipment.
