Official USCG Answer & Rule Citation
Correct Answer: Option C — B
Proper application of pipe dope requires coating only the male threads, leaving the first one or two threads bare to prevent sealant from entering the piping system. This practice ensures a pressure-tight seal while avoiding contamination of downstream components, valves, or instrumentation, adhering to standard marine piping installation best practices.
