The photos on his site of similar sized launchers all appear to have DWV couplers and bushings as well. You can tell by the length of the coupler.

wow! I'm really surprised that Joel would use DWV parts on spudguns. Pneumatic ONES!!!!

I thought he was much more professional than that, to guarantee safety and all... of all people....

The man was selling PVC-based pnuematics. That right there tells me he's not exactly professional about all this. The liability he opens himself up for is INSANE. No businessman (ie, professional) with half a brain would open himself up like that.

So no, I'm not surprised.

Joel did not use DWV parts on pneumatics.

You can not always tell from the length.

There is a minimum socket length for them to meet the NSF-pw standard. Most pw fittings are right at that minimum socket length, but I have seen a few fittings with longer sockets. Those couplers are definitely less than that minimum length and therefore not pw.

Edit: PC the guy linked to in the second post sent his gun to unison for repair. He is reading the dwv off the actual gun.

In what picture?

That would make me awfully sad to hear that he really did use non-PW parts on pneumatic cannons.

A proper disclaimer takes care of that.

meh good point jrrdw.

still i'm disappointed in the DWV.

maybe he ordered them off mcmaster and didn't get the NSF 61 ones by mistake?

i dunno just a thought, because someone told me that the NSF 61 ones are pressure rated
