If the fitting fits the screwed connection, then it should be OK. Use lots

When using a 15mm to 1/2 inch couple, such as Screwfix 12341, should a
washer be used in the imperial side? I must confess I have always used
lots of PTFE but never used a washer. Have I been doing it wrong?

I realise my OP was about male-male couples rather than these but even
then, the male gets connected to something.

Thanks,
