A Compression MTA Elbow is a type of plumbing fitting that combines the features of a compression fitting, an MTA (Male Threaded Adapter), and an elbow. This fitting is used in plumbing systems to create a connection between a threaded male pipe and a section of pipe at a right angle. They are often made from materials suitable for plumbing applications, such as brass or other corrosion-resistant materials. These are designed in an elbow shape, allowing it to change the direction of the plumbing pipe at a right angle. Compression MTA Elbow is commonly used in water supply systems for various applications where a change in direction and a threaded connection are required.
