'E' Type Tube ExpandersView products
The 'E' type expander is a fixed rolling length general purpose tool, which may be power or hand driven. This tool by prior selection can be supplied to provide either parallel or a slightly tapered expansion. In either case the rotation of the tool will draw it into the tube at the required rate.
Standard expanders are supplied with a square head mandrel and three taper rollers to give parallel expansion, but can be fitted with parallel rollers to give taper expansion if required.
