Going through the shop and found this part. I think it is for a fry 117 on the bottom of the jar base where the brass adjustable pipe goes through the packing. Can anyone confirm this?
Thanks, Jeff

YES YOU ARE CORRECT

Thanks Frank !

It's the packing nut for the pump unit. Never seen brass on the slider pipe.

Yes with spanner wrench holes. the regulator pipe nuts are cast aluminum. Dave

Thanks Guys. I thought it was one or the other. I have the aluminum ones in the fry box of parts. Somehow this one escaped....
