Our Gasketing Products

LOCTITE gasketing products are a reliable alternative to conventional compression gaskets to prevent leakage of fluids or gases between flange surfaces.

In addition, LOCTITE anaerobic Gasketing products act as both an adhesive and sealant between two flanges. The liquid sealant completely fills the space between the flange surfaces, thereby preventing the escape of fluid materials or gases in composite machine parts or pipe connections. At the same time, adhesion to the flange surfaces enhances the strength of the assembly.

LOCTITE flange sealing products are applied as liquids, allowing them to fill and seal imperfections on metal flange surfaces. These sealants cure in the presence of metal and the absence of air to form a durable seal between components, with maximum face-to-face contact. LOCTITE flange sealants also eliminate corrosion and provide instant low-pressure seal on assembly. After full curing LOCTITE flange sealants will not shrink, crack or relax and they resist displacement better than conventional gaskets.

Advantages of LOCTITE Gasketing as Compared to Conventional Pre-Cut Compression Gaskets

  • Reduces inventory by using one product for all designs
  • Flows to fill all surface voids and irregularities
  • Eliminates gasket relaxation and creep
  • Prevents gasket displacement and slippage
  • Provides instant seal
  • Excellent chemical resistance
  • Seals to withstand high pressure when fully cured

LOCTITE Gasketing Products Offer 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

Displacement: 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
