Pneumatic set with small weakness

I have the same set together with a Einhell 4020505 BT-AC 200/24 ​​OF compressor and the Einhell Grey inflation adapter set, 8-piece. bought. At the first and just for me purchasing decision use the set there was a setback. I wanted to inflate the tires of our 5 bikes through the Reifenfüllmessers. And I realized that the adapter (Einhell) for the bike port is not sealed to the hose connection of this set (also of Einhell) completed.

Reason: In order to fix the Teflon gasket in the hose connection, a bridge has been soldered. The diameter of the Einhell bike adapter (inflation adapter set) but the inner diameter is not large enough, so that it rests on the web and not on the seal of the tube. Inflation impossible.

Constructive so a bit inconvenient, especially as the adapter is also offered by Einhell should fit yet. This I expect when I purchase goods from a supplier. The other adapters were large enough funnily enough in internal diameter.
Will then again put myself in the professional market and there buy an extra adapter.
