Hi, I think there is a bug with the Chemical Oxidizer. The gaz (Sulfur Dioxide) don't go out throught the Pressurized Tube even if it's in PULL mode. When you place a Gaz Tank next to, it work, but not directly in the Tube :/

@Toarii I'm not sure if it helps, but did you try rotating the block? IIRC you can only extract the gas from particular sides

yes, I have try too, to put the gaz tube around the machine. There is just this face that accept the tube.

stupid question (out of curiosity), is there gas inside the machine? attach it to some power network (is it already connected?) and feed it with the corresponding items.
:D

Yes I have tried, but no result :/

last two options that i can think of (helped me a lot of times) are a) attaching a machine right next to it and b) trying a server restart

Yeah, attach the machine next to the Oxidizer work, but I thing it's a bug for tube. Thank you :)

Fixed in dev.
