Sealant for Gasketing

Gasketing is a sealant between two flanges assembled with screws. The sealant completely fills the space between the flange surfaces, thereby preventing the escape of gaseous or fluid materials in composite machine parts or pipe connections.
Loctite provides sealant products in a range of varieties for this specific application. Slow-curing connections are possible, as is high-strength or highly flexible anaerobic gasketing.

Requirements of the sealant

With gasketing, it is particularly important that the sealant remains intact and leak-proof over the entire life of the connection.

Your Benefits:

  • Single-component
  • Fills all voids – no fine surface finish needed
  • No shimming – no need for re-torquing
  • Excellent instant seal
  • Permits disassembly
  • Flexible Sealants

    Loctite has developed a new breed of silicone sealant solutions. These elastic adhesive sealants eliminate the need to choose between a bonding adhesive and a flexible sealant. Loctite branded two-part silicone adhesives / sealants offer the performance advantages of both, while providing excellent adhesion to various substrates.

    Typical applications for Loctite silicone adhesive products include glass bonding, whether it’s lenses in outdoor lights, assembly of optical elements, window assembly and sealing or bonding mirrors for lasers.

    Silicones are also used for clear potting – bulbs and LEDs for lights and signals, CRT modules in displays, electrical connectors and levels in hand tools.
