Work related.....I'm having real trouble sourcing a UK supplier of 1/2NPT male thread to 15mm compression fitting.

We're selling our products to the american market and they specify 1/2npt male connections on all production and currently all our products have 15mm copper pipe tails....hence I need to find an off-the-shelf adaptor

Fitting

Easy enough to find in stainless, not sure about brass though.
