Where to get white plastic cable grommets - Germany

We are manufacturing a handheld widget. Power cable connects to the widget, and I need to locate a white rubber or plastic grommet as shown in the photos below. It doesn't need to be "anti-stress" 'cos that is already covered within the design. Specs as follows:

Bore diameter needs to be 8.00/8.5mm.

Flange diameter 12.0/13.0 mm.

Length is not too important and can adjust other dimensions on the parts.

The PROBLEM is basically that we only need 3000 at first so not worth getting specially made. Off the shelf we can only locate BLACK but we need WHITE.

I know it's obscure but we have lots of bods in the aircraft industry so just maybe someone can find this for me? I would have thought WHITE would be kinda popular for kitchen tools, but just cannot find them so far.

Beers etc for anyone that knows a supplier.



p.s. "Sleeved Grommet" I think it is called or Kabel-Durchführungstüllen in local money?

Hartnagel near Hbf. have lots of these and can prob. get more many if needed.

Thanks, but I think I have located.

Mods can delete this thread basically. Ta.
