I still think people are grouping the tanks into two categories when in reality there are many more than that. Color is not the only distinguishing factor.
2013 Clippard White Tanks - As far as I know are no longer being sold after the manufacture discovered problems and offered to replace them for free.
Only place I have found a photo is in the 2013 pneumatics manual
http://www.usfirst.org/sites/default...sInfo_RevB.pdf Teams have had many issues with these tanks some of which have been posted in this thread.
Pneuaire -
http://www.pneuaire.com/reca44cuin.html These have been in use for 3 seasons and as far as I know have not had any problems.
AndyMark-
http://www.andymark.com/product-p/am-2479.htm I'm not sure who manfactors these tanks but they look similar to the Pneuaire variety and again I don't know of teams having problems with these tanks.
Clippard 2014 Tank -
http://www.andymark.com/product-p/am-2649.htm Uses ress in hose fitting and has had at least one failure but not explosive failure.
It's my understanding that Clippard just started making plastic air tanks for the FRC market in 2013. I never saw them on their website before then. Where Pneuaire has been producing them with a burst pressure rating of 500 psi and an operating rating of 125psi for several years before the FRC community started using them.
This is a safety matter but we need to make sure we are getting the facts right.
