Fittings material on Aurora Pro and Aurora HPE?

[Cayan]

Question about the fittings of the AIO's Aurora Pro and HPE versions. Are they made of plastic or Brass?
I can see the Eiswolf 2 has the brass version, cause you can see a metal "ring" by the end of the hose, by the radiator connection.
But the Aurora Pro and HPE, by the pictures, looks to have the plastic version of the fittings.
Can anyone confirm?

They are made by Nylon, yes.

Is it safe to use them in a custom loop with a strong pump?

We are using those fittings only for our server customers They are more saver than any other fitting on the market.
