This tool is used to properly install the piston busing assembly into the first stage body of the 1st stage of the Scubapro MK25 and MK25 EVO. 

Position the bushing assembly in the correct order on the thin shaft of the tool (side with smallest diameter) and insert the tool with the assembly into the first stage body. Push the components in place and remove the tool whilst using a twisting motion. Once the bushing arrangement is inserted, the shorter side of the tool (widest diameter) is used to to retain the bushing arrangement in place while inserting the piston.

Made from Acetal.
