Which is better type L or type M copper?
Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine. The beefier Type L is often used underground, in hot water heating systems, for commercial plumbing and for gas line (where permitted).
What is L or M copper?
Type K is the heaviest. Type L is medium weight and used most often for water lines in homes. Type M is thinner and is used underground or for light domestic water lines if local codes allow.
What is type M copper rated for?
Type M, 3/4-inch drawn copper pipe handles a maximum of 701 pounds per square inch at 100 degrees. The same size and type of annealed copper pipe has a maximum pressure rating of just 337 pounds per square inch.
What are the different types of copper tubing?
There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder. Copper offers a high level of corrosion resistance but is becoming very costly.
Is L or M copper thicker?
Type L copper is thinner than Type K but thicker than type M. Type M Copper Pipe: Copper pipe type M wall is thinner than both type K and L copper. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems.
Can type M copper be used for compressed air?
Copper pipe is a common selection for sensitive compressed air systems and when correctly sized and connected is very durable and effective. Type M hard, type L hard and type K soft copper has a working pressure of 250 psig (17 bar).
Can you ProPress type M copper?
Viega® ProPress fittings are for use with type K, L and M hard copper tubing from ½” to 4″ and soft copper tubing in ½” to 1¼” diameters. ProPress fittings are approved for installations in both above- and below-ground applications.
What’s the difference between Type M and L copper pipe?
The Differences between Types L and M The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.
What are the 4 types of copper tubing?
The Differences Between Copper Pipe Types, Explained

What are the different grades of copper?
Different Grades of Copper
- Pure Coppers. Commercially pure coppers contain 0.7% in total impurities in its composition.
- Oxygen Free Coppers. Oxygen free coppers are the purest coppers available.
- Electrolytic Coppers.
- Free-Machining Coppers.
What type of copper is used for HVAC?
Type K Copper Pipe: Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry. Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings.
What is the difference between Type K and Type L copper?
Type K tube has thicker walls than Type L tube, and Type L walls are thicker than Type M, for any given diameter. All inside diameters depend on tube size and wall thickness. Copper tube for air-conditioning and refrigeration field service (ACR) is designated by actual outside diameter.
What are the types of copper?
There are two distinct types of copper deposits: sulfide ore and oxide ore. Currently, the most common source of copper ore is the sulfide ore mineral chalcopyrite , which accounts for about 50 percent of copper production.
What are the different types of copper fittings?
The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.
Is copper plumbing good or bad?
The Good. Copper pipes have been the proven standard of reliability for over 50 years! They are not prone to leaks, are extremely durable, stay fitted tightly, have a long life span and can be recycled, are resistant to heat, and won’t pollute your drinking water.
