Good day
Adapter is included, hose, pneumatic filler is not included. I ordered the set from Metabo, air nipples are mounted with the set.
I am very satisfied with the product.
Greetings Steini

The product is great, but I received it without an adapter. Hose, gun etc. are not included.

It also needs a compressed air set:
Metabo Compressed Air Tool Set EU

An adapter MUST be included:

If you don't find one in your order, just send an email to Galaxus Support and they will send one free of charge. This has happened to me dozens of times.
