The mod adds canisters – small liquid containers (1/50 of a barrel) for almost every liquid in the game. The point is I dont like pipes running near my assembly lines, so I decided to do crafting wihout them. Even though you could transport liquids around on belts with firegrenade’s Fluid Barrel, the canisters are a bit different. You can craft items directly using canister with liquid inside, instead of emptying the barrel into pipe system and then crafting. Unfortunately the canister – unlike barrel – is lost in the process (but its still cheap).
