Power steering rack replacement trouble - fluid lines

Been working on replacing my steering rack for the last couple days and have it almost back on, I just can't get the power steering lines to reconnect onto the new rack at the right angle. I can get them started and they feel fine for the first few turns, but then quickly become increasingly difficult to turn. I'm worried to continue as there is no seal and I don't want to strip the threads. Been trying to slightly bend the lines to correct the angle but so far I haven't been able to find an angle where they screw in easily.

Anyone got experience with this? Is it normal for these lines to feel like they just don't want to go in quite right? Any help would be appreciated. Thanks

 

Have you tried delicately cleaning the threads and nuts with a brass wire brush? Then wipe it?

Try cleaning the threads and then use the ‘Reverse Twist Technique’ when starting the nut. You’ll be spinning lefty loosey. It will allow you to ‘feel’ the thread tip with a slight drop in feel. Once you feel that then start the ‘Thread On Technique’. Righty tighty.

Obviously, you need the hard lines bent properly first.

 

@Professional Hand Model thanks for the reply, I'll give that a try.
