Neptune Systems DOS Tubing 4m

Neptune’s DOS Tubing is a flexible replacement hose designed specifically for use with the Neptune Systems DŌS dosing pump. It has a 6 mm outer diameter and 4 mm inner diameter — matching the original specifications included with the pump — and offers 4 metres of tubing, making it ideal for replacement or extension when re-routing lines or adding extra reach for your dosing system. Compatible with freshwater and reef setups, it keeps your dosing set-up leak-free and ensures smooth flow of additives, calcium/alkalinity mixes, water-change lines, or other solutions handled by the DŌS.
