Designed for IntelliPH chemical dosing systems, this Stenner blue pump tube kit helps restore dependable feed performance when the existing tube has worn, flattened, or become less consistent from regular chemical exposure. The pump tube is a small part with a big role in pH management. Replacing it as part of scheduled service helps maintain accurate acid delivery, reduces the chance of leaks, and supports more predictable water balance in pools using automated chemistry equipment. 2-pack kit for convenient service replacement Supports IntelliPH/Stenner-style chemical feed operation Helps maintain controlled acid dosing and flow consistency Useful for preventive maintenance on automated pool chemistry systems Confirm the installed feeder model and tubing style before ordering to ensure the correct fit.
