Main Diverter Valve Tail Plate / Bush (0862 | R0862 | 248062)
The Main Diverter Valve Tail Plate / Bush Assembly (Part Nos: 0862, R0862, or associated with hydraulic manifold 248062) is a vital mechanical sealing and support component designed for the Main Combi boiler range. Serving as the primary retention plate on the 3-way diverter valve housing, this assembly keeps the internal operational shafts, pushrods, and sealing bushes in exact geometric alignment. It ensures that the valve can dynamically cycle between the central heating and domestic hot water circuits without suffering from external weeping, fluid tracking, or drops in system pressure.
Structural Shaft Alignment: Holds internal mechanical pushrods and seals in a perfectly centered position, preventing localized wear on moving parts and ensuring smooth switching cycles.
High-Pressure Leak Defense: Engineered to form a robust, high-tolerance seal capable of withstanding severe thermal expansion and intense primary water pressures.
Corrosion-Resistant Composition: Fabricated from premium, heavy-duty materials designed to resist limescale scaling, mechanical friction, and the chemical inhibitors present in sealed heating systems.
Direct Drop-In Integration: Machined precisely to original equipment specifications, guaranteeing a clean and immediate fit onto the standard Main cast-brass hydraulic blocks.
