I would allways use Teflon tape on any stainless to stainless threads ,as they are known to gaul and seize sometimes wich will destroy ya thread and make removal very hard ,as I have found out the hard way,seems ta happen more with tapered threads like BSP and NPT .I have not found any information wich suggests its use on stills is a problem.Welding the valve is a bad idear as the heat is likely to destroy the seal on the ball.cheers hillzabilly ;-)
