Long story short... an online order (AMAZON) got canceled because of some BS... and I didn't feel like waiting. This was for some more 1/2" G 1/4 fittings.
So what I had:
2x Apogee GTX 1/2"
2x Swiftech GPU 1/2" plastic
2x 3/8" (ish?)
Had to saw down the swiftech GPU fittings because they were extremely long... Anyways there is more to say, but for now, a successful leak test done:
