U-Connector 180° 25-16mm — DIY BY BRAS

The U-Connector 180° 25-16mm is an airflow connector designed for the DIY BY BRAS system.

Designed to redirect airflow from a 16mm pipe into a 25mm air conduit, it is one of the key building blocks for creating fujara-style instruments and indirect blowing systems.

The U-Connector 180° allows the air supply pipe to run alongside the main instrument body, making it possible to build extended overtone flutes, fujaras, and a wide variety of custom wind instrument configurations.

As part of the DIY BY BRAS system, it can be combined with heads, mouthpieces, rings, sleeves, and other connectors to explore many different instrument designs.

IMPORTANT:
The actual diameter of 25mm and 16mm PVC pipes can vary slightly depending on manufacturer and production batch. To ensure compatibility with the widest range of pipes, DIY BY BRAS parts are designed slightly oversized. While our finished instruments are individually adjusted to match our current pipe stock, DIY parts must remain adaptable to many different pipe sources. For optimal performance, an airtight seal is required. Simply wrap transparent adhesive tape around the pipe to create a custom-fit seal before inserting it into the printed part.
