GPL 295

Krytox™ GPL 295 offers extreme pressure, anti-wear, and anti-corrosion additives. Delivers exceptional  performance in areas that are exposed to both high pressure and oxidizers. Provides an effective fretting corrosion resistance, along with high temperature stability to ensure very long life in these otherwise vulnerable applications. Ideal for lubrication of clutch pilot bearings.

GPL 295 TDS Quote

GPL 255

Krytox™ GPL 255 utilizes low levels of fluorescing agents to allow the grease’s appearance to change under an ultraviolet lamp or “black light”. The naturally white grease appears a yellowish-green color once it is exposed to UV light. This allows the grease to be hidden on a white surface under normal circumstances, but easily visible during manufacturing processes. GPL 255 can also allow confirmation that the grease did not migrate. GPL 255 grease is also available in the oil form as the GPL 155.

Connector Lubricants

Combining the superior lubricating qualities of Polyphenyl Ether with the cleaning power of a hydrofluoroether azeotrope, Miller-Stephenson has created connector lubricant formulations that provide the most advanced total treatment for connectors. These connector lubricants aid the protection of noble metal connector surfaces from wear, oxidation, and tarnishing. In addition to noble metals, our lubricants are inert to virtually all plastics, metals, and rubbers used in automotive connectors and housings. This wide compatibility eliminates fear of galling and seizing of precious metal connector surfaces. They are non-migrating and do not impede the flow of electrical current through the contacts creating a consistent, reliable electrical connection.
