Reliable, Leak-Proof Sealing for Critical Assemblies

LOCTITE gasketing sealants are engineered to provide durable, flexible seals for flanged connections, preventing leaks and ensuring the integrity of mechanical assemblies. These one-part, anaerobic sealants cure in the absence of air, forming a resilient gasket that resists vibration, thermal cycling, and chemical exposure.

What Are Gasketing Sealants?

Gasketing sealants are specialized adhesives designed to replace traditional cut gaskets. They are applied directly to flange faces and cure to form a solid, flexible seal that conforms to flange imperfections, filling gaps and preventing fluid or gas leaks. Ideal for static applications in automotive, industrial, and machinery sectors, LOCTITE gasketing sealants offer:

  • Leak Prevention: Seals against oils, fuels, and coolants.

  • Vibration Resistance: Maintains seal integrity under dynamic conditions.

  • Chemical Resistance: Withstands exposure to various chemicals and solvents.

  • Temperature Tolerance: Performs effectively across a wide temperature range.

Why Choose LOCTITE Gasketing Sealants?

  • Enhanced Leak Prevention: Provides a reliable seal that prevents leaks in critical assemblies.

  • Ease of Application: One-part system eliminates the need for mixing, reducing application time and errors.

  • Versatility: Suitable for a wide range of materials, including metals and plastics.

  • Durability: Offers long-lasting performance under various operating conditions.

How to Choose the Right Gasketing Sealant?

When selecting a LOCTITE gasketing sealant, consider the following factors:

  • Flange Type: Determine if the flange is rigid or flexible.

  • Operating Conditions: Assess the temperature, pressure, and chemical exposure.

  • Application Method: Choose between manual or automated application processes.

  • Cure Time: Consider the required curing time for your assembly process.
