Loctite 234340 Krytox RFE Lubricant

High-performance PFPE grease designed for demanding automotive and industrial applications. The white formulation provides reliable lubrication across extreme temperature ranges and harsh chemical environments. Suitable for technicians and engineers specifying fluorinated lubricants for critical components.

Not for buyers needing a standard silicone

The supplier description mentions silicone heat-sink compound, but the product is a Krytox RFE fluorinated grease, which is a different chemistry. Buyers requiring a traditional silicone thermal paste for CPU or GPU mounting should select a product explicitly labelled as such.

Questions about this item

How does the Krytox RFE formulation perform once applied inside a real truck assembly?

The PFPE-based Krytox RFE grease remains stable across extreme temperatures and resists chemical attack, so it continues to lubricate bearings, slides and seals without breaking down or contaminating adjacent components.

What interface or standard governs the use of this Loctite 234340 grease, and what does it limit in practice?

It meets automotive OEM specifications for PFPE lubricants, which caps the maximum service temperature and defines material compatibility so the grease will not degrade plastics, elastomers or metal finishes in the assembly.
