What kind of o-ring is that? Any thoughts on lifespan and max temp?

@Ryan_Carlyle
I’m pretty sure the O-ring gets removed for this use (it’s there for its intended use).
@Rene_Jurack
Any chance you’re going to market those adapters? I might be interested in a couple.

The o-ring is absent on the assembled nozzle.

I wonder if an all-custom brass nozzle is really needed. Drilling out a 1.2mm Volcano nozzle and parting off the excess thread on the back probably would have done the job.

@Rene_Jurack if you start selling those adapters and blower fans put me on the list for two of each :). Nice ideas.
