Ideal Hydroblock Gasket Kit 176850

The Ideal Hydroblock Gasket Kit (part number 176850) is a set of gaskets and seals for the hydroblock assembly in Ideal Vogue boilers. The hydroblock is a central component in the boiler's hydraulic system, managing water flow between the primary circuit, domestic hot water, and heating. These gaskets and seals ensure watertight connections at the hydroblock, preventing leaks that can lead to pressure loss, component damage, or reduced performance. This kit is manufactured by Ideal and is suitable for a range of Vogue models. Worn gaskets can cause water leaks, pressure loss, and potential damage to the boiler's internal components, so timely replacement is important.

• Water leaks or weeping around the hydroblock assembly
• Visible cracks, hardening or flattening of the gaskets
• Loss of system pressure requiring frequent top-ups
• Overheating or kettling due to air ingress
• Discolouration or debris on the gasket surfaces
• Dripping from the hydroblock area
• Corrosion or mineral buildup on the gasket surfaces

• Check your boiler's GC number and model against the compatibility list.
• Confirm part number 176850 or alternative 1782631.
• Inspect the hydroblock for other worn seals that may also need replacing.
• Ensure the boiler is isolated and depressurised before fitting.
• Always refer to the boiler's installation and service manual for specific guidance.
