Product description

The Triple Mouthpiece 25mm is a part designed for the DIY BY BRAS modular system.

It allows you to play three pipes simultaneously, unlocking rich musical possibilities such as chords, drones, layered harmonies, and complex textures, while remaining fully compatible with the modular ecosystem.

The mouthpiece is intentionally designed slightly oversized to accommodate natural diameter variations of PVC pipes, which can vary by ±0.2 mm depending on manufacturer and batch.
To ensure a perfect, custom airtight fit, the design is intended to be adjusted using transparent tape around the pipe, allowing you to create a tailored seal for each connection.

Pipe compatibility

– PVC IRL pipes (European standard)
– Designed for 25 mm outside diameter pipes

⚠️ Please check your pipe diameter before ordering
