Type L vs. Type M Copper Pipes: What’s the Difference?

Copper Pipe and Tube:

Copper Pipes have long been the standard hard pipe in the plumbing industry, and they are also used in healthcare to transport medicinal gases. Copper Pipes have proven to be extremely long-lasting. Copper Pipe and Tube are popular due to their ability to withstand extreme cold and heat. Copper pipes are recyclable and can be installed outdoors. Copper Pipes are highly flexible and can extend long distances throughout the home. Copper Pipe is extremely durable, it does not require any additional support materials to meet your specifications. Copper tube is frequently used in HVAC systems to deliver hot and cold tap water as well as a refrigerant line. The two main types of copper tubing are soft copper tubing and rigid copper tubing. To join copper tubing, a flared attachment, compression connection, or solder is used.

Manibhadra Fittings is one of the leading Copper Tubes manufacturers in India. Copper has a high resistance to corrosion, but it is becoming increasingly expensive. There are two types of copper tubes: rigid copper and soft copper. Copper tubes are most often used to supply cold or hot tap water, but they can also be used in HVAC systems as a refrigerant thread. Type L, Type DWV, Type K, and Type M are the most common thicknesses available for tubes made of copper in the United States and Canada.

The Distinctions Between Copper Types L and M

• The primary distinction between types L and M is their pressure rating and wall thickness. The most common sizes of copper pipe are 12 and 34 inches.
• Type M ½ inch has a wall thickness of 0.028” and type L ½ inch has a wall thickness of 0.04”. The wall thickness of type M ¾ inch is 0.032”, while type L ¾ inch is 0.045”.
• In general, type L is more expensive than type M. The reason for the price difference is that type L has thicker walls and thus weighs more.
• As a result, type l needs more copper to produce, resulting in a higher production cost than type M. Since type L weighs more than type M, the cost of transportation is also higher.
• Copper pipes of similar size and type have the same external diameter, making them suitable for making plumbing connections with the same fitting.
• Because of the different wall thicknesses, the interior diameter varies depending on the form. Form M ½ inch, for example, has a diameter of 0.569” and type L ½ inch has a diameter of 0.545”.
