• Operations of disassembly and reassembly of internal components, where it is appropriate to restore the seal with dedicated gaskets.
• Activities of restoration after inspections or cleanings, when the existing gaskets are no longer in optimal condition.
• On-board or workshop spare parts management to reduce downtime during service.

Advantages of the correct spare part

Choosing a gasket kit dedicated to your heater allows you to work with components consistent with the assembly, maintaining an orderly and professional approach to maintenance.

Why replace gaskets during the intervention

• Seal restoration after opening the unit: gaskets can deform or lose effectiveness once removed.
• Reduction of unforeseen issues during reassembly, avoiding having to stop work to find individual elements.
• More streamlined maintenance: having the main gaskets in a single kit helps to follow cleaner and more consistent intervention procedures.

Usage and operational notes
