I should know this but, I'm drawing a blank. I want to order Polyurethane O-Rings but for got what size they are?
Any help would be appreciated. Thanks.
Nobody...? ??? ??? ???
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.
