Those that you need, of course, is not there ... ;-)

I was fairly sure that this, quite extensive sealing range, includes all seals that I need.
Primary a 1/2 inch rubber seal with 12 mm hole diameter.
Of course this happens this was not available!

Tough luck, maybe it works in the next start-up, or if I need a seal next time.

Overall, this range is quite inexpensive, but unfortunately this is reflected in the quality of the seals again.
Only the rubber seals left a relatively unclean processed impression.
Mainly "webbed" at the edges, occasionally greasy surfaces and jagged edges on individual seals tarnish the image.
The Fiber seals see actually quite good.
