Improving Flange Sealing and Gasket Performance with LOCTITE® Liquid Gaskets

Cut gaskets can leak. It’s a fact of life. While surface irregularities are the most frequent cause, other causes include:

●  Gasket relaxation – compression set

●  Gasket displacement/extrusion

●  Flange bowing

●  Flange deformation

The Issues with Mechanical Gaskets

●  Over time, they lose their elastic properties and become less resilient

●  Continual pounding of the gaskets by the flanges causes a decrease in the gasket thickness, which can lead to leaks

●  Gaskets can be squeezed out between flanges by a combination of compression and internal pressure

●  Over-tightening of cover plates and bolt-holes can easily break/distort cut gaskets Finding replacement gaskets for older machinery can be impossible

●  Gaskets do not always store well and can become brittle or get damaged while in storage, and keeping the right one for each equipment application can get costly

The Solution: LOCTITE Liquid Gaskets

All LOCTITE gasket solutions provide for reliable, leak-proof seals

●  Will not settle, slip or relax - maintains fastener tension

●  Fill all voids and gaps - preventing leaks and weeping

●  Distribute stress evenly and will not crack or tear

●  Require no re-torquing

●  Prevent corrosion ensuring ease of disassembly

●  Have excellent chemical resistance, high blowout resistance and are easy to apply

LOCTITE 518

Flexible, high-strength anaerobic gasketing material for use on rigid iron, aluminum and steel flanged mating surfaces. LOCTITE 518 features:

●  Greater tolerance of surface contaminants for a more consistent cure

●  Better flexibility for thinner, lighter weight flange designs

●  Better gap cure seals flanges with reduced machining tolerances

●  High performance on inactive metals without a primer
