The primary focus when selecting fittings for a plumbing project is compatibility. This ensures that the fittings will properly connect with the pipes being used in the system, preventing leaks, ensuring secure connections, and maintaining the overall integrity of the plumbing installation. Compatibility takes into account factors such as the size, material type, and pressure ratings of both the fittings and the pipes, which is crucial for the efficient and safe operation of the plumbing system.

When fittings are compatible with the existing plumbing materials, they contribute to a reliable system that meets local building codes and regulations, which can prevent costly repairs or modifications later on. Therefore, while price, availability, and brand reputation may also play a role in the decision-making process, they should not overshadow the importance of ensuring that the fittings are the right match for the plumbing components being used. This compatibility is essential to the functionality and safety of the overall plumbing system.
