This 1/2" FPT x 3/8" FPT Stainless Steel Concentric Reducer Coupling is your secret weapon for creating smooth transitions between pipes of different diameters in your homebrew setup or DIY plumbing projects! Here's why it deserves a spot in your toolbox:

  • Effortless Downsizing: Effortlessly connect a larger 1/2" Female Pipe Thread (FPT) pipe to a smaller 3/8" FPT pipe, ensuring a controlled reduction in flow rate or perfect fit for smaller diameter lines.

  • Concentric Design: The straight, aligned connection ensures both pipes remain centered along the same axis. This simplifies installation and maintains a clean aesthetic for your project.

  • Permanent, Leak-Proof Connection: The butt-weld, beveled openings on each end are designed for strong and secure welding to stainless steel pipes (requires welding expertise and equipment). This creates a permanent, leak-proof connection ideal for high-pressure or critical applications.

  • Durable Stainless Steel Construction: Made from high-grade stainless steel, this reducer coupling resists corrosion and is perfect for handling liquids in your homebrew setup or water lines.


  • Homebrew Plumbing: Connect pipes of varying diameters in your wort chiller, transfer lines going to smaller gauges, or for attaching smaller diameter equipment.
  • DIY Plumbing Projects: Transition between different sized pipes for water lines, drains, or other plumbing applications (where appropriate for welding).
