FAQs of Type K Copper Tube

1. What is Type K copper?

Type K copper tube is the thickest-walled copper tube (of the standard copper Type K, L, and M) used in plumbing, mechanical, and industrial systems. It offers maximum durability, highest pressure rating, and superior corrosion resistance, making it suitable for demanding applications such as underground water lines, fire protection systems, and medical gas distribution.

2. What is Type K copper pipe used for?

Type K copper pipe is used in applications that require high strength, high pressure capacity, and long-term reliability, including underground water service lines, HVAC and refrigeration connections, fuel, oil, and gas distribution lines, oxygen and medical gas pipelines. Its durability and thick walls make it the industry standard for critical infrastructure.

3. Can Type K copper be used underground?

Yes. Type K copper tube is the best choice for underground installation due to its thick walls, corrosion resistance, and ability to withstand soil conditions and pressure variations. It is commonly used for buried water supply lines, main water distribution systems, direct-burial fuel and gas lines where permitted by code. Both soft Type K coils and hard Type K can be used underground, though soft coils are often preferred for fewer joints.

4. What type of copper is used for refrigeration?

Refrigeration systems typically use ACR copper tube, which is specially cleaned, dried, and capped to prevent internal contamination. While Type K can be used in some refrigeration connections, ACR copper is the standard due to cleanliness requirements, pressure suitability, compatibility with refrigerants. ACR tubing is sized based on outside diameter and is labeled as "ACR" for HVAC/R use.
