L Tubing (Copper L Tubing)

L tubing refers to a type of copper tubing that is thicker and more durable than M tubing, making it suitable for various plumbing applications, including water supply lines, heating systems, and medical gas distribution. Copper L tubing is commonly used in residential and commercial plumbing due to its resistance to corrosion, high pressure, and temperature. It is marked with blue color coding for easy identification. The thickness of L tubing makes it suitable for both indoor and outdoor installations, as well as for underground applications. Proper handling, cutting, and joining of L tubing, often through soldering or compression fittings, ensure a reliable and leak-proof system.
