Which type of copper tubing is acceptable for propane installations?

• A. Type A or B
• B. Type K or L
• C. Type M or N
• D. Type C or D

Answer: (B)

Type K and L copper tubing is acceptable for propane installations due to their specific physical properties and ability to withstand pressure and temperature fluctuations that can occur in gas systems. Type K copper has the thickest walls among the common types, making it highly durable and suitable for underground applications. Type L has slightly thinner walls than Type K but is still robust enough for both residential and commercial propane installations. Both types are relatively resistant to corrosion, which is essential when dealing with propane gas, as it can affect the longevity and safety of the piping system. The use of these types ensures compliance with safety standards and helps prevent leaks, which could lead to dangerous situations. Therefore, utilizing Type K or L copper tubing is crucial for maintaining safety and operational efficiency in propane gas installations.
