The brass tee must be chosen carefully to fit each pipe, and also to meet the project requirements for temperature and corrosion resistance. The diameter and wall thickness of the brass tee must match pressure and flow requirements. Local plumbing codes often specify the types of fittings that should be used on different types of projects to ensure a safe and effective installation.

There is a variety of methods of joining the brass tees to the surrounding pipes. Many metal pipes and connectors are threaded, and can be screwed together by hand or with a wrench. When using threaded brass tees, users should take care to choose appropriate male or female tees based on the project. Others require the use of special glue or solvent, while some are welded for a long-lasting bond. Metal fasteners, or couplings, also offer an effective way to join pipes and brass tees.
