1/2 Copper Tubing
1/2 copper tubing is one of the most widely used sizes in plumbing, HVAC, refrigeration, and gas distribution systems. Known for its compact size, durability, and corrosion resistance, this tubing is ideal for residential and light commercial applications requiring efficient fluid flow.
Its versatility and ease of installation make 1/2 copper tubing a preferred choice for water supply lines, heating systems, and small-scale industrial piping.
What is 1/2 Copper Tubing?
1/2 copper tubing refers to copper tubing with a nominal diameter of 1/2 inch. It is manufactured in different wall thickness types such as Type K, Type L, and Type M, each designed for specific pressure and usage conditions.
This tubing size is typically used in branch lines and smaller distribution systems where moderate flow capacity is sufficient.
