1" would be your best bet . Use the boots for the fittings , buy a roll of the tape , and order 20% from what ever you figure ..
Its a sightless cost ,but you will feel better ..

This thread is old, but if you go to Johnstone Supply in Redhook and hang out for half an hour, you'd probably find a few techs who know geo.

Re: Neg subcooling
Glad you found the issues.
Sometimes old tools are better than new shiny tools. It like having a multimeter that doesn't work. If you can't trust it it leads you down the wrong path
Not even looking at the sub cooling if the OA is 87 your liquid saturation can't be below that temp but its 10 degrees less. LL temp of 90 seems low with an 87 OA so the whole high side seems wrong. But you already found the issue

Some industries did, maybe still do, have paid tech support. Early in the call they get you CC number. In general dealing with the general public can be very time consuming.
Your situation is a bit different, you seem to know exactly what you want, you just can't find it.
For the money I would try @EdTheHeaterMan's supplyhouse.com solution posted above.
Pictures like this give me the feeling they are the same part.
Re: Neg subcooling
Okay update. hooked up my old s-man 380s got normal subcooling 9. Which told me my new 482s had a problem. So so I did a factory reset on my new gauges and got correct readings.
I would not haveI would not have guessed that a brand new set of gauges would be doing that. That explains why I never seen settings like that before.
My thanks to everyone that contributed.
