The Hanicks Vaillant Gasket Kit (MPN: 0020038679) is a vital maintenance resource for HVAC technicians and homeowners looking to resolve or prevent gas and water leaks in various Vaillant boiler systems. It provides a comprehensive selection of replacement O-rings, gaskets, and washers specifically engineered for critical components like heat exchangers and gas valves. While this kit is highly effective for routine maintenance, it is essential to remember that all gas-related boiler repairs should be carried out by a Gas Safe registered engineer to ensure safety and compliance.

This is a high-quality compatible gasket kit manufactured by Hanicks designed to meet or exceed the performance specifications of the original Vaillant components.
No. Gas boiler maintenance involves gas-carrying components and must be performed by a Gas Safe registered engineer.
It supports Vaillant actoSTORE 15, various ecoMAX models (613 through 646), and ecoTEC plus models (415 through 630).
The kit contains the replacement parts. Installation procedures are typically found in the specific technical manual for your Vaillant boiler model.
If your boiler is leaking water internally, losing system pressure, or if an engineer has identified a degraded seal during an inspection, this kit is the appropriate repair solution.
Check that the gasket was seated correctly and not pinched during installation. Inspect the pipe connections for hair-line cracks that may exist outside of the gasket interface.
Apply a thin layer of manufacturer-approved silicone lubricant to the O-ring to help it slide into place without distortion.
To use this kit, first isolate the boiler from both the power and gas supply. The kit is compatible with the Vaillant actoSTORE 15, ecoMAX 613-646 series, and ecoTEC plus 415-630 series. When installing, always ensure the seating surfaces for the new gaskets are clean, free of debris, and dry. Do not use chemical solvents or abrasives on the plastic or metal housing, as this can cause improper sealing. Proper care involves using high-temperature silicone grease where recommended by the manufacturer to ensure the new O-rings seat correctly without pinching. Always perform a tightness and leak test after installation before returning the boiler to full service.
