I found that a thin smear of silicone goes a long way to seal those. You don't need to crank down on the nuts with a 3ft. breaker bar, but the o rings should compress enough to seal properly, and without the nuts vibrating loose. A short open end wrench pulled snug by hand, and a small extra bump for good measure, is what I usually do.

Like sgcuda said, silicone is your friend! No need to tighten the snout out of them, just snug them up and take some time to seal every gap w/ a thin bead of silicone or it will leak. Even the Doty (DMI) sealing rings leak, for me anyway, but they are better then the Milodon washers.

Well that's a loaded question......
Snug as it will go without distortion...Thinner the pan, the lighter you have to go....And yes, rtv,,,I used to have blue aluminum washers that captured the o-rings so they didn't squeeze out. Problem was most fittings weren't long enough to use them most of the time.. Went to the copper washer captured style 0-rings....and lots of rtv before a drop of oil goes in...
My new setup by Billet Fab uses a static pickup and AN16 welded fitting....no leaky washers...

The Ultra Gray Ford spec stuff is very substantial. Or the real silicone black 16B.
If the results don't match the theory, change the theory.

You guys scare me with your unbridled use of rtv !!! Personally I wound NEVER in a million years use that crap anywhere near a fuel or oil fitting. You are just begging for trouble if the fitting ever needs to come apart. You will have bits of that crap everywhere you don't want it.
I this particular case, pipe sealant is the only type of sealant that should be used. It will stay soft and if the part ever needs to come apart the sealant can be wiped off. There is no hardened sealant bits to get anywhere it doesn't belong.
As far as how tight to do those washers ... tight enough that they won't come loose !! There is a groove cut on the back of the pickup fitting to contain the o-rings. Tighten the nuts till the pickup is tight against the pan - the o-rings aren't going anywhere !!
I'll use the pipe sealant. The rubber O-rings that come with the Milodon 21464 washer/o-ring kit are .20 (1/8 in) thick. Instruction is to put this o-ring on the inside (washer outside) and they definitely do not crush down so the the pickup seats against the pan. I will tighten the backing washer until the rubber o-rings are .10 (1/16 in) squished. I will also use pipe sealant on the outside lock-nut threads so hopefully they won't loosen up from vibration. Then I will fill the pan with oil to bench test for leaks...

Use something thinner for your bench test. Cold oil won't leak like hot oil will.

I have a system one filter, so its easy to check when I change oil. I install my oil pickup just like most who replied, with silicon, I like the gray. And I seldom get metal in my filter, but every oil change I get pieces of RTV. So far no problems, but you may have something about using to much RTV.

I will also use pipe sealant on the outside lock-nut threads so hopefully they won't loosen up from vibration. Pipe sealant has teflon in it. If anything it will help those nuts to loosen. I'd suggest a couple drops of blue loctite instead.
