Tubing inside a peristaltic pump wears out from constant flexing long before the rest of the unit does. This replacement inner hose is built from durable Pharmed BPT tubing — food-grade and certified to FDA and USP Class VI standards — for the C10, C20, and C30 pump series.
Beyond food-grade certification, the tubing holds up to a wide range of dosing chemicals, including nitric, phosphoric, and citric acid, as well as concentrated potassium hydroxide and potassium carbonate. It's flexible and fully autoclavable, making it a durable fit for both hobby and commercial-grade dosing setups using the replacement peristaltic pump, and it ships with connectors included for a straightforward installation.
The tubing sits inside the pump housing, accessible by loosening the two front screws. Always flush and empty the tubing before replacement to avoid chemical exposure.
Pharmed BPT tubing meets FDA and USP Class VI food-grade standards.
Resists exposure to acids and bases commonly used in nutrient and pH dosing.
Can be sterilized by autoclave, supporting sanitary dosing setups.
Ships with 4x6mm hose connectors for a complete, ready-to-install replacement.
