3 8 Copper Tubing for HVAC, Refrigeration and Plumbing Systems
3 8 copper tubing is one of the most commonly used sizes in HVAC and refrigeration systems. Its compact size, flexibility and excellent thermal conductivity make it ideal for refrigerant lines, water supply and light industrial applications.
Due to its corrosion resistance and long service life, 3 8 copper tubing is widely preferred in residential, commercial and industrial installations.
What is 3 8 Copper Tubing?
3 8 copper tubing refers to copper tubing with a nominal size of 3/8 inch (approximately 9.52 mm outer diameter). It is typically used in applications requiring moderate flow and precise connections.
It is manufactured using high-quality copper such as C12200 and is available in soft (annealed) and hard (drawn) forms.
Types of 3 8 Copper Tubing
Type K Copper Tubing
Type K has the thickest wall and is used in high-pressure and underground applications.
Type L Copper Tubing
Type L is widely used in HVAC and plumbing systems due to its durability.
Type M Copper Tubing
Type M has a thinner wall and is used in low-pressure applications.
ACR Copper Tubing
ACR tubing is specially cleaned and sealed for refrigeration and air conditioning systems.
