Is TPU Oil Resistant and Which type makes a good Oil Seal? I have an old crank style blower for my coal forge and I need a seal to keep the oil in the system. It does not have any heat.

TetraHydroFuran is the only solvent I know of that touches TPU… it is not something that you encounter very often and I doubt it is in any oil. It is not a 💯 answer but I personally would be pretty confident Room Temperature oil wouldn’t effect TPU. Now Hot engine oil would melt TPU no problem, so depends on the heat you experience at that part. HF TPU has a higher flow temperature, which means when cooled it locks into place faster for easier printing but is subject to melting and deformation at 200c like any other TPU.

Thank you for that information. That is extremely helpful.
