70% to passIn application, which of the listed sealing devices is most similar to an O-ring?
AV-ring
BU-ring
CQuad ring
DCup seal
AI Explanation
The correct answer is C) Quad ring. A quad ring is a type of sealing device that is similar in function to an O-ring. Like an O-ring, a quad ring is a circular, elastomeric seal used to create a tight, leak-proof seal between two mating surfaces. The quad ring gets its name from its cross-sectional shape, which resembles a square with rounded corners, as opposed to the circular cross-section of an O-ring. The other options, V-rings and U-rings, are different types of sealing devices that are not as directly comparable to an O-ring in terms of their design and functionality.
