Double Flare Upset Punch – 101857 Series – 220-028 | 0.125 TOD

Built to mate with its corresponding die, this Double Flare Upset Punch forms the upset or double-flare shape in 1/8″ (0.125″ decimal) tube, roughly 028 wall thickness. Getting this step right sets up the tube wall so the finished flare has enough material to seal properly. It is a common wear item in hydraulic end-forming tooling kits and is worth replacing at the first sign of galling or rounded edges. It is part of the 101857 series; compatible with DF tube end forming machines, and is a good fit for shops standardizing their hydraulic end-forming tooling.
