[PSUBS-MAILIST] O-rings

[Dan H.]

John,

Are you sure you really want an O-ring with a one inch cross section??????????
You'd need to machine a groove just under an inch deep and an inch in across to accept it.  If your hatch cover is what the print calls for, it's not think enough for a groove of that size.  

The .275 cross section is plenty.  The two mating surfaces being flat and mating with no gap is much more important then the O-ring cross section.  

You should be fine with the O-ring called for.

  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.
