I thought AN fittings went by 1/8ths but they in fact go by 1/16ths. So what I ended up getting was

It was still too small but the biggest Earl's offers. I took the spring and twisted it to make it a little larger, should do the trick.

If you want one to last, make your own.
Take a 36" length of 3/32" 309 or 316 tig wire and wrap it around a 1" pipe. Take the ends and turn 90° inside so they don't cut into the hose. It will spring back to just enough to get in.
Last past our lifetimes.

The spring is 12" long and 1 1/4" diameter.
