1377 valve outer o-ring is 111. Inner valve o-ring is 012.

I am using Viton Duro 75; they are working fine.

OK, In case you need both o-rings for the valve
inner ->    012
outter ->  111
Flat top -> 012

I'm only using buna 70 for the valve and never have problem for the past 4 yrs and used buna70 - 012 for the flat top at first then tried buna90 and it lasted 2xlonger. IMHO urethane is overkill for static o-ring application. :-*

I am using Buna 90, Just because of tube thread issues on PCP. Thanks for the info.
