50mm adapter for vacuum cleaner - Kärcher WD 7.700 P

this is an adapter to fit a 50mm suction hose to a Kärcher WD 7.700 P (may also fit other kärchers).
i needed this to fit my cyclonic dust separator.

the snap in snapper fits very tight and comes back out only with some persuasion.

so if you have to take it in and out fequently, you might want to add some clearance her and there…
