Dielectric Grease for Trailer Connectors
18029

Dielectric Grease for Trailer Connectors
The protective barrier of AGS Dielectric Sil-Glyde Connector-Protector compound is superior to external wraps, tapes, acrylics, and aerosol silicone oils because a solid film barrier is directly applied to both the male and female mating surfaces of the connection to lock out moisture and corrosion. Using dielectric grease on electrical connectors helps prevent corrosion and increases reliability.

  • Prevents Electrical Failures From Moisture And Corrosion
  • Waterproofs
  • Seals
  • Insulates
  • Protects Bulbs, Sockets and Trailer Plugs
