Question 1 of 27070

If you attempt to tighten a leaking hydraulic fitting with pressure on the system, you will __________.

🔍 Key Concepts

• Hydraulic system pressure and how it affects threaded fittings • Why working on pressurized systems is dangerous and often ineffective • How fluid pressure acts on threads and sealing surfaces of a fitting

💭 Think About

• Imagine trying to turn a nut that is holding back very high-pressure fluid. What is that pressure doing to the threads and the sealing surfaces? • In real maintenance practice, do mechanics usually tighten hydraulic fittings with the system pressurized or depressurized, and why? • Think about whether pressure inside the line would make the parts easier or harder to move relative to each other.

✅ Before You Answer

• Verify what happens to the movement of threaded parts when internal pressure is pushing them apart or against their seats • Consider standard safety procedures for hydraulic repairs: is pressure usually on or off? • Ask yourself which option explains why technicians normally relieve system pressure before tightening a leaking fitting.
