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
