🔍 Key Concepts

• O-ring seals and where they are typically used in hydraulic systems • Differences between static seals (no movement) and dynamic/rotary seals (moving shafts) • Effect of system pressure (high vs low) on O-ring suitability

💭 Think About

• For each choice, ask: is this sealing a rotating shaft or a non-moving joint? How does that affect O-ring life? • Which component is most sensitive to extrusion, wear, and damage if an O-ring is used at very high pressure and speed? • Think about which part of a hydraulic system most commonly uses O-rings in practice: pumps, actuators, valves, or housings?

✅ Before You Answer

• Identify which options involve a rotating shaft versus a non-rotating part • Consider the pressure level in each option and how O-rings behave at high vs low pressure • Ask whether additional support (like backup rings/nylon inserts) would normally be required for an O-ring in that location
