Suggestions for 8 Gauge waterproof connection

I am looking to create a 12 volt connection under the truck to connect a 12 volt portable air compressor. I rather not open the hood in the rain or snow. I did a bunch of searching and all the nice Deutsch waterproof connectors only go as big as 10 gauge. Looks like the arb compressor is using 8 gauge. Anyone have any suggestions for a 2 wire waterproof connector?

Found this on amazon.

That looks like a good option. There’s also judiciously wrapping with rubber tape and then electrical tape over that.

Heat shrink?
