Connecting to new basin tap tails

[peter54]

I have some new taps which came with flexible pipe tails. The O-ring end goes into the tap block, and at the other end there is a captive screw connection with a washer. What should this connect to?

I thought it might be a 10mm compression fitting, but it's too big for that (and too small for 15mm). Any help appreciated.

Male thread or female thread?

Female thread (so it needs a male-threaded fitting)

Male comp straight adaptor should fit or you can purchase replacements with compression ends at your local plumbers merchants, mind the male end that screws into tap comes in different sizes.
