How to build GSE for Hybrids (Rattworks)?

[Bulma]

I need to assemble GSE for rattworks I80 motor. Filling tube is 1/8". I got N2O tank, but now I need additional parts to complete GSE. Tank has 3/4" fitting. I guess I only need a solenoid valve and pressure gauge, right?
The problem is that I can't find adapters for 1/8" (3mm) tube, that would work at high pressure, at local shops in my country (eastern europe). Do you know any good online shop that sells that kind of stuff?

Ordinary brass compression fittings will work. You can get them from McMaster. Start here.

Black Dog Rocketry sells very nice GSE https://www.blkdgrkty.com/ . I built my own GSE and I used solenoids from Aerocon https://aeroconsystems.com/cart/ . You will need to know what type of fitting your tank has like CGA 660 or CGA 236. They are listed on the Skyripper page https://www.skyrippersystems.com/tips/HybridTips.html. I like to use the prestolok (quick disconnect) or push to fit fittings to connect to the fill tube. They work better than the compression fittings because they have barbs that grab the nylon tubing and they are reusable.
