Gaskets are used to prevent leakage of fluids or gases by forming impervious barriers. For successful gasketing, the seal must remain intact and leak-free over a long period of time. The gasket must be resistant to fluids and/or gases, and withstand the operating temperatures and pressures to which it is subjected.

LOCTITE gasketing products are self-forming gaskets that provide a perfect seal between components, with maximum face-to-face contact, eliminating flange face corrosion. A low-pressure seal is formed immediately on assembly, with full cure in 24 hours giving a joint that will not shrink, crack or relax.

LOCTITE Gasketing products offer a much higher performance and provide numerous benefits over traditional sealing systems such as pre-cut gaskets The major causes of failure and leakage of compression gaskets are:

Surface contact: Compression gaskets do not provide total contact between the gasket and the flange surfaces. Therefore minor leakages may always occur (weeping rate)

Compression set: Compression gaskets relax under dynamic loads and decrease in thickness, with subsequent loss of bolt tension in the flange joint resulting in leakage

Extrusion: Gaskets can be squeezed out between flanges

Bolt hole distortion: High stresses are transferred to the gasket material under the bolt head, causing the gasket to crack, tear, rupture or extrude

Advantages
