I tried the search to no avail.
I need to know how the safety switch seals to the MC. Is it an o-ring or a copper/Alum washer. Either way I cant seem to find it listed in a parts diagram. Any help is appreciated, part # would be amazing. Thanks Dyno |

Get some Mituyoyo calipers and spec. the parts out. . Go to the McMaster-Carr website and find them. They sell o-rings specifically designed for high heat applications with pneumatic fluid.
You should have no problem finding them. The only caveat is you’re gonna have 100 of each and you’ll have to pay about $40 plus shipping, but then you can just sell the kit here and quadruple your money lol |
