Question 307General Subjects - QMED

The correct answer is D) toward the oil pressure being sealed. The reason this is the correct answer is that spring-reinforced oil seals are designed to have the lip or tail of the seal facing the direction of the oil pressure being sealed. This orientation helps to ensure a tight seal and prevent oil leakage. The lip or tail of the seal is the flexible part that makes contact with the shaft or surface being sealed, and it needs to face the direction of the oil pressure to effectively contain the oil. The other answer choices are incorrect because they do not align with the proper installation orientation of a spring-reinforced oil seal. Option A would allow oil to potentially leak past the seal, while options B and C would not provide the necessary sealing pressure against the oil flow.
