I'm almost 99% sure this is fine, but I wanted to double check. 3/8in brake tubing, flared with the 3/8ths die - is it safe and sane to use a 10mm fitting? Or do I need to go sacrifice some money to the metric gods to fix Dad's terrible Honderp?
(For the record, 3/8ths fittings will totally thread into a 10mm hole - and not seal)
