What it is

MALVERN M3786 SENTINEL X100 is a corrosion inhibitor for central heating systems, supplied under the Malvern brand as part number M3786. It is a general trade consumable rather than an appliance-specific spare part, so it is not tied to any one boiler or cylinder model.

Before you order

  • Check that M3786 is the part number required.
  • Confirm the quantity needed for the system being treated.
  • Check that the product is suitable for the system in question before dosing.
