Re: [PSUBS-MAILIST] Tight or Loose O-ring Grooves



Hi Brent. Still....good lookin' drawings.
The Parker book didn't really "encourage" a dove tail groove but where used it said or showed  ( in the cross section sketch ) a max of 5 degrees I think.
My memory's not that good anymore but I'm pretty sure that's what was shown.
