The RA EXP Hydraulic Expander Set has an all new compact design from the market frontrunners Robinair, to allow use in the harder to access areas. It also now has an angled and more practical design, requiring less effort as a result. With laser-engraved expander heads, the different heads are now significantly easier to identify and attach. This is a light-weight tool to provide easy copper, aluminium and brass expansion with only a few pumps of the lever. For more information, please look at the data sheet below.
