3 8 Copper Pipe for HVAC, Refrigeration and Plumbing Systems
3 8 copper pipe (3/8 inch copper pipe) is a widely used small-diameter pipe designed for precision flow applications. It is commonly used in HVAC systems, refrigeration units and residential plumbing where controlled flow and compact installation are required.
Manufactured from high-purity copper, this pipe offers excellent thermal conductivity, corrosion resistance and durability, making it ideal for modern piping systems.
What is 3 8 Copper Pipe?
3 8 copper pipe refers to a copper pipe with a nominal size of 3/8 inch (approximately 9.52 mm outer diameter). It is used in systems that require moderate fluid or gas flow with high efficiency.
This pipe is typically made from copper grade C12200, known for its strength and corrosion resistance.
