Which product prevents threading seizure and is used on light assemblies, battery brackets, and thermostats?

• A. Tef-gel
• B. RTV 3140
• C. High Temp Grease
• D. Anti- seize

Answer: (D)

Preventing threading seizure comes from using a compound that stays on the threads to reduce friction and protect against corrosion and galling. An anti-seize compound creates a thin, heat-tolerant film on threaded joints, which keeps bolts from sticking even after exposure to moisture, heat, or dissimilar metals and makes future disassembly much easier. That’s why it’s a go-to for parts like light assemblies, battery brackets, and thermostats—areas that can see temperature changes and corrosion over time. The other products serve different purposes: Tef-gel protects electrical connections and helps prevent corrosion there, RTV 3140 is a silicone sealant for sealing gaps, not for preventing seizing, and high-temp grease lubricates but isn’t formulated to prevent galling and corrosion on threads over the long term.
