Neptune Systems DOS Replacement Head Cap

Genuine Replacement Pump Head for the Neptune DOS Dosing System

The Neptune Systems DOS Replacement Head Cap is a genuine replacement pump head assembly designed for the Neptune DOS Dosing & Fluid Metering System. This complete assembly includes a new head housing, peristaltic tubing, fittings, and roller wheel, allowing you to restore your DOS pump to peak performance with a quick and simple replacement.

As the peristaltic tubing naturally wears over time, replacing the head cap helps maintain accurate dosing, smooth operation, and long-term reliability. Neptune Systems recommends replacing the DOS Head Cap approximately every 700 hours of pump run time, depending on usage.
