Couldn’t get the nut off without the whole drain pipe turning…

We now see that it's not a nut or drain bolt, it's a cap...

I cannot see that drainzit makes a tube that fits my Ariens engine.

They make them to fit almost all small engines, including yours. It would replace the entire drain tube. However, with the drain tube you have, perhaps a drain valve is the better solution.

Went to several places for a crush washer...apparently my nut is not designed for one.

Yes, no crush washer on a cap. Internal O-ring, maybe. Always lead with your make & model number to get the best answers up front.

So your cap should be 3/8" NPT. A coupler + a 3/8" NPT EZ-110 drain valve would likely do it...

all done w oil change. I cannot see that drainzit makes a tube that fits my Ariens engine. Installed tube nice and tight. added Teflon tape to nut. Went to several places for a crush washer...apparently my nut is not designed for one. Manual could be better written. Thanks for help and feedback all. View attachment 197864

That's a pipe cap also with tapered threads. If it gets chewed up and leaks, replacements can be found at pretty much any hardware store in plumbing. Same with the pipe . . . it's just a standard plumbing nipple.
