Autococker Orings

[jokers]

So I have been putting together an Oring kit for my Cockers and other markers and i think i am done i thought that i might help others out and put the information that I used here in case anyone else needs it since it seems that the orings for markers have moved to kits only. If there is something that i missed or that you know of I would love to either add it here or if an admin want to clean this up and sticky it just let me know and I can close this. Some of this information is copy pasted from Reddit r/Autocockers101 forum and others is from the Oring store autococker kit. The kit has duplicates of reddit info when they differed on the durameter. The actual kit has most of the orings listed in Reddit i just deleted what was repeated.

Use HBNR instead of standard buna for anything dynamic. Much better abrasion resistance.

that 003 40d is a little soft for most autocockers. That’s like sub 40psi. There is a neat chart somewhere on the internet with durimeter and psi

[Magmoormaster]

I prefer urethane for anythign that moves, particularly on the 3way. Bunas are too sticky.

[latches109]

They offer better abrasion resistance but are prone to swell with water, do not compress as well, and are significantly more expensive.

I can't find the ANS valve disk on that site, am I not searching correctly?

[batmite]

Sorry to be pedantic, but it's durometer not durameter. (skateboarder in the past, wheel hardness you know)

I know one letter... but....

[jokers]

No problem i fixed it, just to make sure there was no confusion later.

[latches109]

how about my "durimeter" typo - obviously I was shooting at the o

I do not know latches109 you need to be careful it seems that batmite is part of the grammar crusade and he might take offense. Lol.
