A compression fitting is a type of plumbing or automotive fitting that is used to connect two pipes or tubes together. It typically consists of a nut, a compression ring (also known as a ferrule), and a compression seat. When the nut is tightened, it compresses the ring onto the seat, creating a tight seal.

Exhaust gas temperature (EGT) is the temperature of the gases exiting the combustion chamber of an engine. Monitoring EGT is important in performance tuning and engine diagnostics, as it can indicate the efficiency of combustion and potential issues such as overheating.
