Standard Couplings range from 110 - 175mm diameter, they incorporate a stainless steel central shear band and worm drive clamps. Approved for use in adoptable sewers and installations where heavy earth loads may be encountered.
Drain Couplings range from 110 – 165mm diameter. For use where the coupling will not be subjected to shear or heavy earth loads such as an insertion junction in a drain or in vertical applications such as industrial rainwater pipes.
Adaptor Couplings range from 110 – 260mm diameter. The stepped coupling allows the connection of pipes of vastly different diameters and materials without the need for a separate packing bush.
All Wavin flexible couplings comply with BS EN 295-4:2013. The standard couplings also comply with WIS 4-41-01. The rubber used conforms to BS EN 681-1:1996.
