Question 1 of 27070

Copper tubing is manufactured and classified as type K, L, and M. Which type would offer the greatest wall thickness for a given nominal size?

🔍 Key Concepts

• Copper tubing types (K, L, M) and how they differ • Relationship between type designation and wall thickness/pressure rating • Typical usage of each type in plumbing and marine systems

💭 Think About

• Think about which type of copper tubing is usually chosen for highest pressure or underground service. • Which type is considered more heavy‑duty vs more economical for general use? • If you line up K, L, and M for the same nominal size, how would manufacturers logically assign letters from thickest to thinnest?

✅ Before You Answer

• Verify which type is specified in codes for maximum strength/pressure and buried service. • Check which type is commonly used for standard interior water lines versus light‑duty applications. • Remember that all three types do NOT have the same wall thickness for a given nominal size—one is thickest, one is medium, one is thinnest.
