Thread: Never a dull moment.

Just an idea, how about a good layer of plumbers tape to help fill any gaps in the threads that might be causing you grief prior to the o-ring?

Can anyone confirm the thread size of the male thread on the steering box end of the high pressure PS pipe? I've measured it as about M15 x 1.5 but would like to know for sure and try to get a nut to check whether the thread on my hose is faulty.
Thanks,
