There's your problem. I mean poor quality control. To make those work, you have to freeze them hard and keep them frozen by working fast. Freeze hard, slice thin, drill hole, place on plug and tighten. All before they thaw. My trouble generally comes when the wife walks in to the kitchen while I am using the slicer. At that point, a leaky plug is the least of my troubles.
I'm saddened to say that it took me a time or two of reading that before it sunk in... LOL!
To the OP, I'm not sure why you're having issues? Never before have I had them? If you're bent on using a rubber type plug, try one for a Chrysler minivan 3.3/3.8 V6. They have a large diameter head and a captured, replaceable o-ring and use the same threads.
EDIT: Here is what I'm referring to:
NAPA
Picked up a 14mm1.5 at NAPA today. It's what I'm looking for. No more crush washers that I never seem to have. P/N 704-1929
