Need a recirculating system for your gold concentrator set-up? Then you need Gold Cube's Tub Flange!
Connect multiple tubs for continuous water circulation. Ships with PVC pipes that slip into the Flanges to create a water tight seal between the tubs. The system leaves the tubs totally portable and nest-able. The Flange system is a must where gold is fine, water is scarce, and every drop counts!
An ideal portable and contained small production system has a 3 tub sediment system (3 Tub Kit) using the tube flange to connect them together. A very good system has a smaller tub inside a larger tub then one next to it connected by flanges (2 Tub Kit).
