Re-using Compression Fitting, Nut, and Crimped Ferrule: If the sensor is re-installed, the compression fitting and nut can be re-used. The crimped ferrule, however, may need to be cut away from the sensor to remove it, making it unusable. If you can remove the crimped ferrule without destroying it, and if it can still provide an effective process seal, you can probably re-use it at least the nu
