Dunno what all the fuss is about with Polybute Pipe and fittings we have used it here for years and still do, however over the years some of the crimp fitting have changed as a few failed earlier than expected but were the ones with the copper band compression rings – we now use alluminium clamp rings and have found them to be excellent here.
Different rings clamps – different crimping tool required – the manufacturers have to make some cash somewhere!!!
