What type of fitting is commonly used to join two pipes of the same material?

Couplings are specifically designed to join two pipes of the same diameter and material, creating a continuous and secure connection. This type of fitting ensures a tight seal, which is crucial for preventing leaks in plumbing or piping systems. Couplings can accommodate various materials, such as PVC, copper, or steel, making them versatile for different applications.

The focus on coupling as a fitting type highlights its functionality in applications that require a direct connection between two segments of piping, without changing the direction or splitting the flow. In situations where a joint is necessary for maintenance or repairs, couplings offer a straightforward solution for reassembly and disassembly.
