Type L copper tubing is a medium-thickness tubing commonly used in plumbing and low-pressure systems. It has a thicker wall compared to Type M copper tubing, offering enhanced durability. Type L copper is typically used for water lines, heating systems, and other applications that do not involve the high-pressure demands found in HVAC systems.
Type L copper is available in both soft (annealed) and rigid (hard drawn) forms. The thickness of Type L copper tubing allows it to handle moderate pressures without compromising the integrity of the system. This makes it suitable for applications that involve water, low-pressure heating, or other non-demanding applications.
Type L copper tubing is often used in:
● Water Supply Lines: It is a standard choice for residential and commercial water supply systems. Its thicker walls offer additional strength and durability compared to Type M tubing, making it ideal for this application.
● Heating Systems: Type L copper tubing is widely used for hydronic heating systems and hot water lines. Its ability to withstand moderate heat and pressure makes it an excellent choice for carrying hot water through piping systems.
● HVAC: Although Type L is not typically used for refrigeration, it is sometimes used in low-pressure HVAC systems for carrying coolant. However, for high-pressure applications, ACR copper tubing is the preferred choice.
Its affordability and durability in lower-pressure systems make Type L copper tubing the most commonly used tubing in residential plumbing and heating systems.
Type L copper fittings are designed to create tight, leak-free connections in plumbing and low-pressure systems. These fittings, which include couplings, elbows, and tees, are essential for ensuring the reliability and safety of a plumbing system. The thickness of Type L fittings is matched to the tubing, providing strength and resilience in various applications.Type L copper fittings are widely used in both residential and commercial systems due to their excellent sealing capabilities, ensuring long-lasting and reliable performance in low-pressure water systems.
One of the most noticeable differences between ACR and Type L copper tubing is the wall thickness. ACR copper tubing is designed for high-pressure applications, and as such, it has a thinner wall to increase flexibility and reduce the risk of rupture under pressure. In contrast, Type L copper tubing has a thicker wall, making it more suitable for low-pressure systems like plumbing.The thicker wall of Type L provides greater strength and durability for carrying water and other non-pressurized fluids, while the flexibility of ACR tubing makes it ideal for refrigeration systems where movement and flexibility are needed for installation.
While both ACR and Type L copper tubing are made from high-quality copper, the alloy composition differs slightly. ACR tubing is typically made from a higher-grade copper, specifically designed to ensure performance with refrigerants, which require a particular composition to prevent corrosion and maintain structural integrity. Type L copper, on the other hand, is a standard grade used for general applications.ACR copper tubing's composition ensures that it can handle the unique stress and pressures of refrigeration systems, whereas Type L copper is built for durability in plumbing and low-pressure heating conditions.
ACR copper tubing is primarily used in refrigeration, HVAC, and solar water heating systems.
