@Rob K There is no tech node that allows that but i can reassure you that the pressure limits are currently "bugged" under RO (fixed the the next official release though). In the mean time, you can use the following MM patch to allow the parts work in the surface of Venus or deep under the atmospheres of the gas giants: @PART[*]:HAS[~maxPressure[<4000]]:BEFORE[RealismOverhaul] { %maxPressure = 20000 } (This will increase the pressure tolerances from 4 MPa to 20 MPa - Venus has a surfa
