Which component corresponds to grease fitting for lubrication?

• A. Water displacement thing
• B. Potting compound
• C. Encapsulate
• D. Grease gun fitting

Answer: (D)

Grease gun fittings are lubrication access points on machinery. They’re specifically designed to accept a grease gun so you can inject grease under pressure into bearings or other moving parts, with a built‑in valve to keep dirt out and prevent leakage. That direct connection for applying lubricant is why this component matches the idea of a grease fitting for lubrication. The other terms don’t fit as components for lubrication access: a water displacement item is used to displace moisture, potting compound is a protective material used to encapsulate and seal components, and encapsulate is the verb for enclosing something—none describe a port or fitting used to apply grease.
