I have several of the old 462s, I call them "the king of the testing wbs"
one modded by mildhab has a JB Weld'ed compression fitting in the inlet, bored out to take a 1/2" Cu pipe
- I use it for nozzle testing < g >
to enlarge the outlet do the same, drill it out but put in a piece of Cu pipe directly
(trying to tap it and then get a seal WILL cause grief)
