FLANGE 90465-11M10 PAHT-2.5X60

Function and technical context

The PAHT-2.5X60 flange is a fixing and sealing component that works in the cooling circuit of nautical engines, ensuring a hermetic connection between ducts and system components. Its fundamental mission is to maintain the integrity of the passage of cooling fluids under continuous pressure and the vibrations inherent to the marine environment, avoiding leaks that would compromise the efficiency of engine cooling. A defective or poorly tightened flange in this system can cause overheating of the engine, internal corrosion of water passages and, in extreme cases, entry of seawater into critical circuits.

When to replace this part?

Inspect this flange during each seasonal inspection: if you notice rust deposits around the gasket, moisture in the mating area or coolant leaks, it is time to replace it. Flanges subjected to continuous vibrations and temperature changes tend to lose elasticity and closing pressure between 3 and 5 years of intense use in navigation. Replacing it preventively during major overhauls avoids costly emergency repairs at sea and ensures safe cooling all season long.
