Info needed: Cooper-T Surge vavle

[netsurferdude2]

I picked up this mag off Craigslist with a spyder and a bunch of tanks and remotes for $60.

I was wondering if anyone had any more info on that red adapter that allows you to use a 4oz tank as a expansion chamber. The Fubarius on MCB told me it was a Cooper-T Surge Valve. IS this the whole story?

That IS the whole story. Teammate of mine had one a long time ago.

Are they worth anything nowadays?

I can't see the pictures but it sounds like I had what you are describing. Had it way, way back in the day, like mid-90's. It was a really large anti-siphon expansion chamber setup used back when everybody used CO2. I bought it at EMR in PA one winter when my Mag did not like the cold at all. Worked perfectly but rather bulky. And why did Cooper-T annodize everything red? But all it did was take CO2 and liquid CO2 from your tank move it into the piggyback 3.5oz tank setup with a anti-siphon tube. The piggyback tank would trap any liquid CO2 and give it plenty of room to expand. But it was really an extreme case. Most of the time a standard anti-siphon CO2 tank would work then and of course N2 and compressed air fixed just about all of the earlier problems. I still remember having a triple coil (about 3') of ss hose between my AIR valve and vert adapter to catch liquid CO2.
