🔍 Key Concepts

• How hydraulic compression fittings seal (what actually makes the fluid-tight joint) • Difference between a threaded seal and a compression/ferrule seal • Which part is designed to be sacrificial and deformed during tightening

💭 Think About

• Look at figure C and trace where the pressure would act if fluid tried to escape. Which part actually presses against the tubing to stop that leak? • If the fitting starts to leak after being properly installed, which component is most likely damaged or improperly seated—the threads, the body, or the compression element? • Which choice suggests fixing the leak by improving the thread seal, and which choice deals with the component that provides the metal‑to‑metal seal on the tube itself?

✅ Before You Answer

• Identify which part (I, II, III, or IV) is the compression sleeve/ferrule that bites into the tube. • Confirm whether the threads in this type of fitting are meant to hold pressure, or mainly to pull the sealing parts together. • Ask yourself: in standard maintenance practice, which part of a compression fitting is normally replaced when it leaks rather than just tightened again?
