80158-357-51-R | Allen-Bradley | Nyogel Anti-Corrosion Grease

Configured for contact surface protection in industrial electrical assemblies, the Allen-Bradley 80158-357-51-R (80158-357-51-R Anti-Corrosion Grease) provides direct physical execution of oxidation prevention and environmental sealing for conductive interfaces.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 80158-357-51-R functions as a specialized chemical barrier designed to maintain signal integrity at electrical connection points. By preventing the formation of insulating oxide layers on metallic contacts, this lubricant ensures that data communication across Profinet and EtherNet/IP deterministic networks remains free of intermittent connection faults. While the grease itself is a passive material, its application is necessary in high-density I/O installations to mitigate the risk of corrosion-induced resistance fluctuations, which can degrade the communication stability of modular PLC backplane bus segments and sensitive instrumentation interfaces.

Frequently Asked Questions

Q: Is this lubricant conductive?

A: No. Nyogel is a dielectric, synthetic hydrocarbon grease. It is designed to seal electrical contacts from moisture and air to prevent corrosion without creating electrical bridges or short circuits between adjacent pins.

Q: Can this grease be used on high-voltage power terminals?

A: Yes. Its dielectric properties make it suitable for preventing oxidation on various power and signal terminations. Ensure the grease is applied sparingly to cover the contact surface without contaminating surrounding insulating materials.

Field Installation Guidelines

1. Ensure the electrical contact surfaces are clean and free of existing contaminants, debris, or old lubricant before application.
2. Apply a thin, uniform layer of the grease to the metal contact areas using a clean applicator or lint-free cloth.
3. For multi-pin connectors, ensure the grease does not bridge across adjacent pins to avoid potential impedance issues in high-frequency signal lines.
4. Re-mate the connectors to spread the lubricant evenly across the contact interface; verify that the connection is fully seated to ensure the seal is effective.
5. Wipe away any excess grease that has been displaced during the mating process to prevent the accumulation of airborne dust or conductive debris.
6. Periodic re-application may be required in harsh industrial environments; follow site-specific maintenance cycles for connector inspection and lubrication.
