MPN: OL0884443 | Product Series: Beta / Better / Expert Plus | Product Type: Concealed Outlet Valve | Operation: Mechanical / Dual Flush Setup
Key Features
- Exact Tolerances: Formulated to click precisely into your existing Oli cistern cradle, saving you from dismantling complex under-counter frame plumbing.
- Variable Flow Tuning: Integrated adjustable overflow and float slides allow precise custom scaling of partial and full fluid dump cycles.
- High-Grade Washer Seal: Pre-fitted with a premium silicone-rubber base gasket designed to strongly resist chemical chloramine degradation and scaling.
- Heavy-Duty Armor: Structurally dense polymer build handles continuous water immersion over long lifecycles without warping or shifting.
Installation Note
Isolate the primary water supply and completely drain down the tank before performing maintenance. Accessing this mechanism is done through the standard service gap located behind your front flush plate. Unclip the old valve tower from its base basket, ensure the basket seating area is completely free of loose grit or limescale, and slide the new OL0884443 mechanism down until it locks firmly into place.
