[Osprey]

Fed up with poorly fitting spanners rounding off 15mm and 22mm plumbing compression fittings.  Even Conex is oversized – must get the correct tools. 

ISTR we kept the old ½ inch and ¾ inch BSP threads when the metric came in .  Does that mean that the nuts should be ½ inch BSW and ¾ inch BSW? 

I realise there is some variation between manufacturers but what should they be?
