Kinetico DO Cap Part Number 9044A

Kinetico DO Cap – Part No. 9044A

Genuine Replacement Discharge Outlet Cap for Kinetico Softeners

The Kinetico DO Cap (Part No. 9044A) is a genuine replacement Discharge Outlet (DO) cap designed for Kinetico twin-tank water softeners fitted with the 2020C-series control valve.
This precision-moulded cap secures the discharge outlet port and houses the DO Cap Seal (Part No. 8628), creating a reliable watertight closure that prevents leaks and maintains consistent system pressure.

Key Benefits

✅ Prevents Leaks – Ensures a perfect seal at the discharge outlet when paired with the correct O-ring (8628).
✅ Restores System Integrity – Stops unwanted water bypass and pressure loss.
✅ Built to Last – Manufactured from high-grade, durable polymer for long-term reliability.
✅ Precision Fit – Designed specifically for Kinetico 2020C-series control valves.
✅ Simple Installation – Quick and easy to replace during service or rebuild.

When to Replace

Replace the DO cap if you notice:

• Water leaking from the side of the control head

• Visible cracking or deformation of the existing cap

• Loss of pressure during service or regeneration

• The O-ring (8628) is being replaced — it’s good practice to fit a new cap at the same time

Installation Advice

• Ensure the O-ring (Part No. 8628) is installed and lubricated with food-grade silicone grease.

• Tighten the cap evenly and securely by hand — do not over-tighten.

• Check for leaks after returning the system to service.
