A tool to remove or tighten the service valves (Schrader valve) of cooling-/ heatpump systems. My standard tool is sometimes too big to use it properly.
But it should work on the valves of tires too.
You will need the tip of a “Refco” Schrader-tool. Havent found it on amazon.

I´ve printed it in PC, because in my job it will get in contact with hot, oily objects.
0,4 nozzel, 4 perimeter, 8 bottom/toplayers, 30% grid infill.
I´ve used it several times. Works well until now.
