[PSUBS-MAILIST] O-rings

[subvet596 at optonline.net]

Hi All:
 
I need O-rings for the entry hatches which are 24" id. 26" od. he question I have is, what is the best cross section size to use The parker site has the E1157 @ .275 it seemed a little small to me. I have not yet machined the dove -tail grove yet. Also are there any specs. available for setting up a 3 dog mechanism, able to open from inside or out? 
 
Looking forward to the convention.
