🔍 Key Concepts

• Look closely at figure D and imagine how you would physically get that straight, rigid tube between two fixed fittings. • Think about proper hydraulic tubing alignment and why small bends or offsets are normally used between fittings. • Consider what happens to the sealing surfaces and ferrules if the tube has to be forced sideways to make it reach.

💭 Think About

• If both ends of the tube are fixed and the tube is perfectly straight, can you slip the nuts and flares onto both fittings and fully tighten them without springing or bending the tube? • When a tube is slightly misaligned or forced into position, what part of the connection actually ends up carrying the side‑load: the threads, or the sealing/flare surfaces? • Which option best describes a condition where the tube is under constant mechanical strain so the fittings never seat squarely and are likely to leak under pressure?

✅ Before You Answer

• Verify which choice talks about improper installation/alignment of the tube and fittings, rather than exotic material behavior under pressure. • Eliminate any answers that describe tube behaviors (stretch, twist, or big dimensional changes) that are not realistic in normal hydraulic service. • Focus on the option that matches a practical mechanic’s problem: you can’t get both ends lined up and tightened without putting a side load on the joint, so it tends to leak.
