Gold Cube Tub Flange for 3 Tub Kit Sediment System for Gold Prospecting GC-16

The Gold Cube Tub Flange GC‑15 is a critical component for building a 3-tub sediment system—a portable, self-contained solution for serious gold prospectors. It allows for seamless connection of three tubs using standard PVC pipe, forming a closed-loop water circulation system that dramatically improves fine gold recovery and sediment control.

This flange system works with the Gold Cube’s Vegetation Kit, ensuring that the PVC pipe slides smoothly into the flanges, creating a watertight seal between each tub. Perfect for use in remote areas or environments where water is limited.

Key Features:

• Engineered for 3-Tub Kits – Connects three tubs together, allowing sediment to settle in stages while reusing water through continuous circulation.
• Watertight, Leak-Free Design – Creates tight, secure seals with standard PVC pipe, eliminating leaks and conserving water.
• Portable & Stackable – Keeps the tubs lightweight and fully nest-able for easy transport and storage between uses.
• Optimized for Fine Gold – Critical for locations where water is scarce and fine gold recovery is a priority—every drop counts.
