4 And 5 Roll Condenser Expanders (Series 72-C)

SKU: N/A

These expanders are used on light Gauge tubes of stainless steel, titanium, and materials of similar hardness. 5-Rolls with light wall tubes can prevent triangulation of the tube to the tube hole. Wilson Thin Guage collars also offer a large advantage for projection of tube. All assemblies come complete with mandrels, rolls, cage, and collars with a 1/16-Inch standard recess.
