The Model BTH-2 Tube End Sizer is one of a family of four tube end sizers built by TRIDAN. Being hydraulically powered, it has an increased capacity for tubes of different materials with larger diameters and heavier wall thicknesses. One additional sizer in this family is the Model BTA-2 Tube End Sizer which is an air powered version of the BTH-2, and uses the same tube end sizing collets. We also offer the Models BFA-2V and BFA-2H Tube End Sizers/Flarers which are air operated tube end sizers, that size and flare the tube end.

All of these Tube End Sizers are designed to provide a solution to the problem of tube end belling or sizing. This operation is required when tubes of the same diameter are to be joined or for the insertion of return bends into straight tubes or hairpins, which have been expanded by the following TRIDAN Expanders:
Flexpander
Porta-Expander
Hexpander
Qual-Ekon Vertical Expander

GENERAL MACHINE DESCRIPTION:
The TRIDAN Model BTH-2 TUBE END SIZER is a portable hand-held device designed for the sizing of copper, aluminum, mild steel, cupro-nickel, and red brass tubing of diameters 3/8" (9.525mm) to 3/4" (19.05mm). (Other sizes are available. Consult factory for details.) Its operation is extremely simple with the operator placing the specially designed expanding collet inside the tube end to be belled or sized, activating the thumb switch and the tube end being belled to the pre-set inside diameter.
