1 1/2 Copper Tubing
1 1/2 copper tubing is a widely used size in plumbing, HVAC, refrigeration, and industrial piping systems where moderate to high flow capacity is required. Known for its excellent corrosion resistance, durability, and thermal conductivity, this tubing size is ideal for applications requiring efficient fluid and gas transport.
Its larger diameter compared to standard residential tubing allows it to handle higher volumes, making it suitable for commercial buildings, industrial systems, and large-scale installations.
What is 1 1/2 Copper Tubing?
1 1/2 copper tubing refers to copper tubing with a nominal size of 1.5 inches. It is available in different wall thickness categories such as Type K, Type L, and Type M, each designed for specific pressure and application requirements.
This tubing is commonly supplied in straight lengths and is used in systems requiring reliable performance and long service life.
