O Ring Sizing Question

[Random Dude]

Hi all, I'm interested in making a O-ring kit to include in my save-a-dive box.

Would appreciate it if you guys can assist in providing advice for the sizes and materials needed.

Below is the list of O rings I hope to include

1. MK17 Evo Din First Stage O ring
2. Yoke Tank Valve O ring
3. Low Pressure Regulator Hose O ring
4. Low Pressure Inflator Hose O ring
5. High Pressure Hose O ring
6. Second Stage O rings (for hose to second stage connection) (SP G260 and R380)
7. SPG O ring
8. Any other O rings that you guys think would be a good idea to include

Thank you guys in advance!
