[PSUBS-MAILIST] O-rings

[subvet596 at optonline.net]

Hi Dan:
 
Sorry for the confusion, a run on sentence will do that. I was asking about the size/cross-section of the O-ring. The 316 stainless steel ring would be welded to the dish lid in which the O-ring would be mounted using a machined dove-tail grove,   
 
Thanks for the input.
 
John K.
