Understanding Copper Tubing Types
Copper tubing comes in various types, each designed for specific applications. The three primary types are Type K, Type L, and Type M, with Type K being the thickest and most durable.
Type K Copper Tubing
Type K copper tubing has the thickest wall among copper tubing types, making it ideal for high-pressure applications. It is commonly used for:
- Domestic water supply
- Fire protection systems
- HVAC systems
- Fuel oil lines
- Solar heating systems
Type K is available in both soft and hard forms, allowing flexibility in installation.
Type L Copper Tubing
Type L copper tubing features a medium wall thickness, suitable for a wide range of plumbing and HVAC applications. Common uses include:
- Refrigeration systems
- Water supply lines
- Heating systems
Type L tubing is often preferred for its balance between durability and flexibility.
Type M Copper Tubing
Type M copper tubing has the thinnest walls among the three types and is suitable for low-pressure applications. It is typically used in:
- Residential plumbing
- Heating applications
While Type M is more affordable, its thinner walls make it less suitable for high-pressure situations.
Applications of 2 Inch Copper Tubing
