And tighten in one motion without stopping or reversing.  Cu washers can be used just once.  Otherwise heat it to glowing with a torch and quench in water (annealing?).  Can you post a picture of the problem?

Jan S:
Thanks to both of you for advice!

I will try to get some "copper aviation conical crush washers" when I'm back after the summer vacation (the summer road trip went down the drain  :( )

Alec300SD: How does a washer like the one you mentioned look like? Can you send a link to a picture?

You can also make them from flat washers.

Jan S:
Great!

I included two pics. The first from the convex connection at the steering pump (outer thread is M16), the second from the hose/pipe flaring (the pipe is 10mm at base).

I'm a bit confused with the size of the washer. The Amazon-link says 1/2'' Tube OD .... OD probably stands for outer diameter. Do they mean the outer diameter of the washer? Will that washer fit the connection?

What do you think, Alec300SD?

Alec300SD:
The photo link was just to show what a conical washer looks like.


The half inch (outer diameter) conical washer probably won't fit as one half inch equals 12.7mm.
A 3/8 inch  conical washer (equal to 9.525mm) is probably the best choice if you can't get a metric washer.
