Have a look
I can't see a difference based on this, maybe its how its connected to the tube, I just ask for a Michelin airstop tube and it fits.
More here which confirms its the base
TR-4 (round base) Center/side metal valve (threaded and nuts)
TR-6 (oval base) Center metal valve (threaded and nuts)
Thanks Kommando, I guess the TR4 with the round base would be the one to get.
