Taprite seal size

[cheese1566]

Just got my Taprite regulator from kegconnection.
I was going to order bulk o-rings from mcMaster-Carr for my Corny kegs.

Is the taprite seal that connects to the CO2 tank just a Quad style Oring?

I haven't removed it to look in fear of damage. I searched here and Google, but only find the thread on the keg o-rings.

Hoping I can get more from mcMaster if someone has a order #. I do see Amazon lists them for $1.50 each through Taprite.

(I could measure but what a pain...!)

Mine are going on 5 years and still sealing, called Tap-Rite when I thought one was leaking they sent 1 for free in couple of days, found crack int the valve on the tank thread Airgas exchanged at no charge I had exchanged it the day before.
