Retaining rings for CBC bending formers
CBC supplies the formers of its UNI pipe benders complete with ring; the rings are also available as spare parts. Each ring belongs to the size of its former – for some sizes, CBC makes separate rings for 3D and 4D formers or for aluminium formers.
Several rings fit a metric and an inch former at the same time, for example Ø 16 mm and 5/8″. Three further rings belong to the formers of the FLEX 22, which the manual UNI 22 uses as well.
