Why use a Loctite® Gasketing Product?
Gaskets are used to prevent leakage of fluids or gases by forming impervious barriers. For successful gasketing, it is necessary that the seal must remain intact and leak-free over a long period of time. The gasket must be resistant to fluids and/or gasses, 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 won’t 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 of Loctite® Gasketing products as compared to conventional pre-cut compression gaskets:
• Single-component - easy and clean to apply
• Replace conventional gaskets – reduce inventory
• Fills all voids
• No need for retorquing
• Excellent instant seal
• High resistance to solvents
• Resists high pressure when fully cured
