Here’s the “spaghetti seal” that I ordered from Grainger and have used successfully.
Std, Black, Buna-N Round Cord – 6VFC3|ZUSA-RC-875 – Grainger
There are now two options listed as a rounded 3/32″ diameter or cross section. This one is 0.093″ and the other option is 0.103″. I doubt that the 0.01″ really makes much of a difference. There is a little extra room in the gearcase groove, and the seal gets flattened a bit upon tightening the screws.
I’ll stick with the 0.093″ as seen in the link because I know that it works. This is the “general purpose” option with a medium durometer value (hardness) of 70A.
