76mm/88mm Pipes: This expansion upgrade kit contains 2 sets of expanders. One set for 76mm pipes and the other set for 88mm pipes. Each set enables your 690E machine to clamp onto the respective pipe sizes.
Expansion Kit: Exclusively only for 690E Pipe Freezing Machines and owners. We try to cater to every situation so we designed these to allow repairs on even the larger 76mm and 88mm pipes.
