Excess sealant is likely to cause which of the following?

Excess sealant is likely to cause which of the following?

• A. Stronger joints
• B. Weaker joints
• C. Better heat transfer
• D. No effect

Answer: (B)

Excess sealant alters how the joint seats and seals. Sealant is meant to fill small irregularities without adding thickness that prevents metal-to-metal contact. When too much is used, the extra squeezes out under the bolt load and can smear onto mating surfaces, causing the joint to sit unevenly. This prevents even clamping and can leave small gaps, which weakens the joint and makes leaks more likely. The excess material can also cure in the wrong places or interfere with proper torque, harming the seal and potentially affecting heat transfer. So, using too much sealant tends to produce a weaker, less reliable joint rather than a stronger one.
