"Failproof Flange Sealant
LOCTITE® 518 Gasket Maker 518™ 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
- Make sure this fits
by entering your model number.
- RELIABLE ADHESION. Forms a flexible, solvent-resistant seal that will not tear or decay. Primarily for use on aluminum, iron & steel flanged mating surfaces.
- FLEXES WITH MOVEMENT. Enhances load bearing & shock absorbing characteristics of the bond area. Typically used for Water pumps, thermostat housings, transmission pans, transmission case covers, transaxle casings, O-ring replacement.
- REMOVABLE WITH HAND TOOLS. Parts disassemble easily, even after extended service, and old gasket material can be removed with a putty knife.
- CONVENIENT CURING. 30 minutes to 4 hours with primer. 4 - 24 hours without primer. Cure speed will depend on the substrate used.
- LOCTITE 518 GASKET MAKER replaces almost any cut gasket or coat pre-cut gaskets to increase reliability.
