Reliable flange sealing with Loctite SI 5980

Practical benefits
  • High resistance against oil: You protect timing covers and oil sumps against damage from engine lubricants and glycol-based coolants.
  • Immediate low pressure testing: The joint withstands low-pressure tests right after assembly, allowing you to proceed quickly without leak risks.
  • Fills large flange gaps: The thixotropic silicone formula stays in place without slumping, ensuring a durable seal across wide, flexible surfaces.

In a nutshell

The right choise for

With Loctite si 5980 flange sealant, you create a reliable seal on flexible flanges and stamped sheet metal covers such as oil sumps and timing gear covers. This black silicone sealant provides excellent resistance to engine oils and coolants while easily accommodating high joint movements and vibrations. Its thixotropic formula prevents slumping and fills large gaps evenly across metal and plastic surfaces. Because it cures with atmospheric moisture, assembled parts withstand immediate low-pressure testing so you can keep working without delays. Operating between -55 °C and 200 °C, this 100 ml cartridge delivers a durable, leak-free seal for engine repairs.
