Which compound is applied to valve body bolts during maintenance?

• A. Anti seas compound
• B. Anti seize compound
• C. Grease
• D. Lubricant

Answer: (A)

Applying anti-seize compound to valve body bolts is done to prevent threads from galling, seizing, and corrosion in harsh marine environments, and to make future disassembly easier. The compound stays on the threads, reduces friction between dissimilar metals, and helps you reach and maintain the correct torque without the fasteners binding or tearing the threads. While greases or general lubricants provide lubrication, they don’t offer reliable protection against corrosion and galling, and they can wash away in wet conditions, making removal more difficult later. Anti-seize is specifically intended for fasteners exposed to heat, moisture, and dissimilar metals, like valve body bolts, so it’s the best choice in this maintenance context.
