What exactly are these parts?

[txlonghorn1989]

I picked up this 5-drawer Newmade cabinet a few weeks ago at an estate sale. It included these contents. Most seem to look to be some type of pipe/line fittings. And others don't at all (the wheel-like things with holes and a stem in the 2nd pic on the left). I have no idea. A lot even look like they might be stainless steel. Just wondering who'd be interested in these and what they are? I don't see myself using them and want to get rid of it so I can figure out a use for the super cool cabinet. :0) Any thoughts are appreciated.

Looks like high pressure fittings, presumably for high pressure or cryogenic gas applications.

It appears to be plumbing related. Water/Air/whatever. I can see some teflon tape still on some of the threads. Someone would love to have that collection.

perhaps someone was in the beverage industry? co2, draft beer, soda etc

 

[Copymutt]

Looks like a collective mix. I see some galvanized, some pex, some compression, lots of now costly brass fittings, plugs, some i don't recognize. Don't see much for CO2 cornellius fittings.

Those are all used in the air-gas industry for instrumentation. Maybe he worked in an argon plant and the reason I say argon is the brass, that wouldn’t be used for gas oxygen.

Pneumatic controls and actuator air supply plumbing mostly. Factory setting like a small stamping plant or the like.

Looks like industrial/plant maintenance to me, theres enough of an assortment that it has to be for pneumatic stuff. Anything food or pharmaceutical or chemical would require stainless fittings in my experience

The stainless looks like the stuff we had in the semi-conductor fabs. However it could be from any factory floor.

Thanks for all the replies guys! Guess I'll post them on CL and see if anyone is interested in them.

Sounds right to me. I have a similar assortment of parts in drawers that came with a 48 drawer cabinet I bought on CL years ago. That guy had an injection molding line making fishing lures, but also did mechanical work in the textile business. I've got hundreds of these sort of weird flare elbows and tees. Also lots of oilers and spring loaded grease caps. So, some of this may be for pneumatic actuators and controls, but the same sort of fittings are used for remote lubrication (grease uses surprisingly high pressures).
