Intermittent-Fault Protection


Reduce fretting corrosion on electrical terminals to prevent costly intermittent faults

Save time and trouble with Molykote® brand specialty lubricants. Good terminal contact lubrication can help you prevent fretting corrosion, eliminate difficult-to-diagnose intermittent faults, resulting owner complaints and costly warranty repairs.

Dependable intermittent-fault prevention for electrical connectors

Reduce the potential for intermittent faults
Protecting connector terminals from fretting corrosion can reduce the potential for intermittent electrical faults. Molykote specialty lubricants:

  • Reduce sliding friction to help contacts connect with lower force
  • Displace and seal out moisture, fluids and dirt
  • Absorb the effects of micro-motion, vibration, and thermal expansion and contraction
  • Bond to terminal metals, do not migrate or bleed out, maintain long-term lubricity and corrosion protection
  • Are compatible with connector metals, elastomers and adhesives
  • Facilitate easy connector assembly and disassembly

Reduce fretting corrosion with good contact lubrication
Prevent the buildup of oxidized insulating debris on connector terminals. Good lubrication can help you avoid:

  • Corrosion caused by micro-motion, vibrations, thermal cycling and poor connector terminal contact
  • Increasing electrical resistance as the corrosion builds and spreads
  • Switching from tin-plated terminals, which are most susceptible to fretting corrosion, to more expensive metals
  • Intermittent faults on low-current signal circuits
  • Overheating, melted terminals and open circuits on high-current power circuits
