Brass pipes have been used for centuries for many vital functions, including plumbing, heating and cooling. Long prized for its decorative properties, brass’s malleability and workability are its truly useful traits—especially when it comes to manufacturing pipes and pipe fittings. You can search for the right brass fittings, brass tubing, connectors and nipples for your project—just confirm the diameter of the pipe you need, as well as the length. HVAC pros and plumbers are big on brass pipes, and there are countless industrial, manufacturing, appliance and automotive uses for them as well. To go with your brass pipes, shop for valves and pipe wrenches.
