Airbus Lavatory Sink Strainers O-Ring when in need of replacement requires a special tool to stretch the o-ring into place on the stopper. Ref [figure]. The tool required is XXXXXXX. This tool has been difficult to acquire. The suggestion would be to have the stopper come equipped with the o-ring already attached to the assembly so as to not impact the system with respect to delays in acquiring the tool.
Technician reported difficulties in the installation of an O-Ring on a lavatory sink stopper without the required special tool being available.
