First time using air compressors so not my area of expertise but I know I need to get it right or it's dangerous. I ordered a good silent compressor to use In production but when I went to hook it up to pneumatic tooling I bought the metal coupler on the tooling is too large for the output socket on the compressor.

Checking spec sheet of the compressor it is a 6mm outlet, my tooling has a larger coupler on an 8mm pipe, how do I convert this up to the bigger size? I found some listings on Amazon but they are packs of 20 adapters and I don't trust the quality. Could anyone send me a link to something that would make it work?

Compressor is Einhell TE-AC 24 silent 24l max 8 bar so low end (but enough to fuck you up if I do this wrong) both tooling and compressor have quick connect fittings albeit currently the wrong size.

I am just stuck on how I convert to a larger size socket - complete novice when it comes to compressors.

Thanks
