Supplied in a 50 ml tube (1 pack), it cures when the joint is sealed from air, creating a form-in-place gasket suitable for low-pressure transmission and engine joints. Its thixotropic formula minimizes migration and squeeze-out, helping to keep flanges clean and aligned during assembly.\u003c\/p\u003e\n\u003cp\u003eThe product supports both active metals such as mild steel and passive substrates like aluminum with low copper content. It tolerates gaps up to 0.25 mm (0.01 in) and minor surface contamination from cutting oils, lubricants, anti-corrosion agents, and cleaners containing surfactants and inhibitors. This flexibility makes it practical for real-world workshop and field tasks where surface prep isn’t perfect.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned primarily for aluminum, iron and steel flanges, delivering a consistent seal across common automotive joints\u003c\/li\u003e\n  \u003cli\u003eIdeal for on-the-spot repairs or when a conventional gasket is unavailable\u003c\/li\u003e\n  \u003cli\u003eSuitable for transmission case coverings and engine casings\u003c\/li\u003e\n  \u003cli\u003eThixotropic formula minimizes liquid migration, reducing clean-up and potential mess\u003c\/li\u003e\n  \u003cli\u003eSensor-safe and low-odor formulation suitable for enclosed spaces\u003c\/li\u003e\n  \u003cli\u003eNon-corrosive to typical automotive metals, preserving surfaces during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat LOCTITE 518 can do for you\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSeals close-fitting joints between gearboxes and engine casings as a form-in-place gasket, reducing the need for pre-cut gaskets\u003c\/li\u003e\n  \u003cli\u003eProvides robust curing right after assembly so you can move to the next step with confidence\u003c\/li\u003e\n  \u003cli\u003eTolerates minor contamination from common oils and cleaners, maintaining performance in mixed workshop environments\u003c\/li\u003e\n  \u003cli\u003eOffers automotive aftermarket value by supporting emergency repairs and ongoing maintenance across makes and models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplication tips\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePrepare mating surfaces by cleaning and drying; avoid residual oil or coolant on the contact area\u003c\/li\u003e\n  \u003cli\u003eApply a consistent bead along one flange face, then bring the surfaces together and clamp as needed\u003c\/li\u003e\n  \u003cli\u003eEnsure a close-fit joint; cure occurs in the absence of air; avoid introducing air pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eIn practice, LOCTITE 518 can be a practical choice for fleet maintenance crews, hobbyists, and professional technicians who want a reliable, sensor-safe seal for gaskets in tight spaces.
