450mm x 375mm Twinwall Level Invert Reducer

This 450mm x 375mm twinwall drainage level invert reducer is black in colour, designed to reduce the pipe system from 450mm twinwall drainage pipe down to 375mm twinwall drainage pipe.

For a sealed carrier system, you will require one 450mm sealing ring and one 375mm sealing ring for each reducer.

We highly recommend this product and the rest of the twinwall range to be installed with lubricant to help with pipe jointing fittings and rubber seal connections.

BBA approved and manufactured in the UK by Naylor provides the installer with a reliable product that will perform. This product is designed to suit Naylor Metrodrain Twinwall, therefore it may not fit other manufactures twinwall products.
