Weihrauch HW100/HW101 driver bit/tool
This tool can be used to remove/service the quickfill valve and outlet valve in the ends of a HW100/HW101 air cylinder. It is difficult to service the valves with regular screwdrivers (that are found in most common sets) because they are not large enough to fit the HW100/101 valves, which are normally very tight and difficult to remove without damage. You can use a normal 1/4" bit driver/wrench to hold the bit/tool, which has been made to fit both valves and minimise the risk of damaging them.
This tool will also fit the Air Arms FTP900 fill valve screw, which is handy if you don't have a suitably large enough flat screwdriver.
The tool is made from stainless steel.
There is also a tool in the eShop that is ideal if you need to get the ends out of the air cylinder (which can be very tight) to carry out a service or repair a leaky fill valve. It is also handy for people who have bought an aftermarket cylinder, which need the original cylinder ends swapping over to the new air cylinder.
Please use the tool at your own risk, if used properly it will gives years of trouble free service, if used improperly it may damage the heads of the valves in your air cylinder.
The tools shown in the photos are for reference only, you are buying the hex bit, nothing else.
