Re: conductors through a seal fitting
Standard seal fittings are listed for 25% fill base on the trade size of the fitting. There are "oversized" seal fittings available listed for 40% fill.

See 501.5(C)(6).
You will have to do the math using Tables 4 and 5 in Chapter 9.
I get 3/4 rigid has .549 square inches.
25% of this is .13725 square inches.
Depending on the insulation type, I see from .0031 to .0145 square inches per #18 wire. Worse case, is RFH-2, I get 9 conductors. Best case is KF-2, I get 44 conductors.
The hard part will be separating each conductor with Chico without damaging the conductor.
