The Wing Sung Piston Wrench is a service tool designed for compatible Wing Sung 699, 629, 600, and 630 fountain pens.

It allows you to safely remove and reinstall the filling mechanism when performing maintenance, cleaning, lubrication, or repairs. The wrench engages the piston or vacuum-filler assembly so the mechanism can be dismantled without relying on pliers or other tools that may damage the pen.

Ideal for fountain pen owners who perform their own routine servicing or restoration work.

Compatible Models:
Wing Sung 699, 629, 600, and 630

Use: Removal and installation of piston or vacuum-filler mechanisms

Note: Fountain pen not included. Use care when disassembling your pen to avoid overtightening or damaging internal components.
