Stupid question: Do gas regulators have a use-by date?

dimanche 7 décembre 2014

Hi there,



I've recently taken an interest in welding. Although I'll initially be focusing on MIG welding, I have inherited two sets of oxy-acetylene gear, care of my late Father and Grandfather.



My Father's regulators are CIG brand (they look like these: http://ift.tt/1zAo6BH ) , and would date from the the late 70's or early 80's. The last time I remember Dad using them would have been the mid-90's.



My Grandfather's regulators are branded "L'Air Liquide" and appear to have a 1972 date stamp on them. I never saw them used by either.



Do regulators go bad with age? Realistically, what is the worst that can happen if I attempt to use a bad regulator?



Thanks.
