3 cutting torch attachments
all of which are high quality and
all of which seem to have the same problem.

Maybe the problem is elsewhere?
What do all three have in common besides the same problem?
What are all three attached to?

Try attaching them to something different and see what happens.

The common thread is they are all "salvaged" - and likely not recently
maintained. If the oxygen from the cutting lance can reach the mixer,
it WILL pop.Deformed/overcompressed/hardened "O" rings are a common
cause of internal leakage.
