Hey folks, just picked up an AI 1.9 cu ft vac oven and a cps 2 stage pump. I know I need to order the kf25 adapter for the oven side, but I can't seem to figure out what I need on the pump end. My pump has 3 connection options, 1/4 SAE, 3/8 SAE and 1/2 acme. I've been trying to find 3/8 sae or 1/4 sae to barb connectors, but all I can find are NPT connectors. How are you guys hooking your pumps to your ovens?
