## Overview

LOCTITE 518 is a sensor-safe, anaerobic gasket maker designed for metal flanges, curing quickly in airless conditions to create a medium-strength, oil-resistant seal. Perfect for emergency repairs and OEM-level automotive applications, it fills gaps up to 0.25 mm and tolerates minor surface contaminants, making it a trusted choice for professionals and racing teams alike.

## Description

LOCTITE 518 Gasket Maker is a single component, medium strength, anaerobic sealant which cures when confined in the absence of air between close-fitting metal surfaces and provides resistance to low pressures immediately after assembly of flanges. The thixotropic nature of LOCTITE 518 reduces the migration of liquid product after application to the substrate.LOCTITE 518 Provides Robust Curing Performance. It not only works on active metals (e.g., mild steel) but also on passive substrates such as aluminum with a low copper content. The product offers gap performance to 0.25 mm (0.01 in) and contamination tolerance. It cures in the presence of minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion, and protection fluids and cleaners containing surfactants and corrosion inhibitors.TYPICAL APPLICATIONS include sealing close-fitting joints between rigid metal faces and flanges as a form-in-place gasket, e.g., gearbox and engine casings, etc.LOCTITE automotive aftermarket products are not just OEM-specified, they are also designed by auto manufacturers and lab tested. Engines of nearly every professional race car are assembled and maintained with LOCTITE brand adhesives, sealants, gasket makers, and coatings. Whether gasoline or diesel, from bolts and gaskets to cooling lines and core plugs, Henkel products are used to seal, secure, and repair vehicle components.
