JOINT CREATOR N3 118ML

Function and technical context

Permatex Aviation Form-A-Gasket No. 3 Liquid Gasket Sealant acts as a sealing agent on precisely fitting surfaces, permanently but flexibly sealing the interfaces between caps, flanges, threaded connections and hoses in marine engine cooling, lubrication and exhaust systems. Its slow-drying, non-hardening formulation allows for controlled repositioning during assembly, which is especially valuable in onboard maintenance work where conditions are not ideal. The adherent film it forms acts as a barrier against oil, water and fuel leaks, and is commonly used in Mercruiser and Volvo Penta engines where the integrity of the seals is critical to avoid serious breakdowns during navigation. Its compatibility with machined surfaces and solid joints makes it an indispensable resource in the professional marine workshop.

When to apply or replace this sealant?

The need to reapply gasket sealant is evident when oil or coolant leaks appear in valve cover gaskets, timing covers, exhaust flanges or threaded fittings, as well as when dark stains or persistent moisture are detected in the engine joints after cleaning. Its systematic use is recommended in each disassembly of components that affect sealed surfaces, especially in seasonal maintenance or after cylinder head inspection operations, changing water pump gaskets or intervention in the cooling circuit. Applying it preventively in each reassembly prevents leaks that on the high seas can lead to overheating or loss of lubrication, high-cost breakdowns and difficult solutions outside the port.
