Brass vs. PVC vs. Stainless: Which Should You Choose?

The right pipe fitting material depends on your project’s requirements. You’ll want to take into account water quality, pressure requirements, temperature needs, budget constraints, and environmental considerations.

For durability and versatility, brass is a solid choice. If you’re working on a budget or need a lightweight solution, PVC may be your best bet. For heavy-duty applications requiring top-notch durability and corrosion resistance, stainless steel is the way to go.
