Aqua Master Tools Inner Hose for Peristaltic Pump - Pharmed BPT - Includes 4x6mm Hose Connectors

Restore Accurate Dosing With a Fresh Pump Tube - Single Replacement Hose

A worn tube inside a peristaltic pump makes dosing drift, and drifting doses make nutrient and pH control harder to hold steady. This replacement inner hose gives the pump a fresh flow path made from Pharmed BPT biocompatible polymer tubing. It comes with connectors for 4x6mm hose, so you can reconnect your lines once the tube is changed.

This listing is for one inner hose, sold each. It suits growers who maintain their own dosing equipment and want a spare on the shelf, whether they run a small indoor hydroponic setup or a larger commercial system with several pumps.

• Connectors included — supplied for 4x6mm hose, so you do not need to source them separately.

Frequently Asked Questions

Q: What does this part replace?
A: It replaces the inner hose of a peristaltic dosing pump. The manufacturer lists it for its C series dosing pumps and injection valves. Check your pump series before ordering.

Q: Does it include connectors?
A: Yes, it includes connectors for 4x6mm hose. You can reconnect your existing lines of that size after the swap.

Q: What is a peristaltic pump?
A: A peristaltic pump moves liquid by squeezing a flexible tube with rollers. The liquid touches only the tube, so the tube is the part that wears and needs replacing.

Q: Which chemicals is the tubing rated for?
A: The manufacturer lists nitric acid below 35%, phosphoric acid below 85% and citric acid below 20%. It also lists potassium hydroxide and potassium carbonate as concentrated, and potassium silicate as unknown. Check these limits against your solutions before use.

Q: How should I prepare before changing the tube?
A: Flush and empty the pump lines first so you avoid contact with the solution. Then open the pump housing to reach the tube.

Q: Why replace the tube instead of the pump?
A: The tube is the wear part, so a new one often restores dosing performance at lower cost than a new pump. Replace it on a regular schedule or when dosing becomes inconsistent.
