O-rings sizes 19 Ltr Cornelius kegs

[NicB]

Hi
Is there a sticky here?

Has anyone the sizes (specifications) for the three different o-rings on 19Ltr Corny kegs please?
POST x2
TOP SEAL x1
DIP TUBE X2
Full sets are available but I'm going through dip tube seals fastest.
Thanks in anticipation.

post are AS568A-111 3/32" thick 7/16" internal dia
lid are 1/4 thick 3 1/2" internal dia

Thank you foxbat.
For the dip tubes I've just ordered speculatively 50x for £1.65 13mm od by 2.4mm thickness food grade silicone from china (ebay).

Working on 3/32" is approx 2.4mm
And 5/16" is approx 8mm (7.94mm)
Working backwards ID = OD - 2x thickness.

Opps.... correction

ID = OD minus 2x Thickness

Sounds like it'll be OK. I think you have more margin for error on the dip tube than, for example the posts that really do need to be accurate to seal against the disconnects.

Yes thanks that's my reasoning as well.
I didn't have a spare and as I cleaned my last empty keg just prior to filling I noticed one starting to split..
Thought of wrapping with PTFE tape if it didn't hold but lucky it seated itself and is holding.
