Kit: The item used to build the component. These are the names as they appear in fabrication lists, which does not always match the true name of the item. Except where noted, all of these items are manufactured with a Hydraulic Pipe Bender.

Input/Output: "Generic" connections are pipe fittings that are not explicitly for input or output. "Space" indicates an interface to fluids that are not contained in pipes (e.g., the atmosphere or the contents of a room). "Clamp-on" components have no fittings of their own; they clamp onto an existing Straight Pipe.

One-way: Does the component prevent fluid from flowing the wrong way, from output to input?

Switched: Does it prevent all flow when switched off or unpowered? Except where noted, switched components can be switched either manually or using logic circuits.

Compressor: Will it actively increase pressure in the output and decrease pressure in the input? If no, the component only allows pressure to change toward equilibrium between input and output, or it does not enable any pressure changes.

Max. Pressure: The component will begin to fail when pressure exceeds this. More precisely, this is the maximum difference in pressure between the component's internal volume and the surrounding space. Some components list "60 MPa" because attached pipes will fail, even if the true limit of the component itself is unknown. Even where a higher limit is known (e.g., canisters), this limitation still holds and places a practical maximum on most setups.

Note 1: While the Pipe Gas Mixer will actively compress from output to input, it will stop when either input is empty, to preserve the mix ratio.

Note 2: The Wall Cooler's one-way, switched, and "compressor" qualities apply only to the heat exchange. It does not directly affect the pressure or flow in its attached pipe.

Note 3: The Active Vent will fail at ? MPa. The pressure at which it will stop pumping is configurable through the data network and defaults to 0 Pa for Inward mode and 101 kPa (1 standard atmosphere) for Outward mode.

Note 4: These Volume and Max. Pressure ratings reflect the limits of the removable canisters and tanks. Note that the 101 MPa limit of a Gas Canister is considerably higher than the 60 MPa overall limit of a pipe network.

Note 5: These Pressure limits are what max can be set on the regulators. Regulators themselves have no inner atmosphere and thus no inner pressure that would break them.
