DuPont Krytox lubricant - door seals, hinges, latches, squeaks and rattles

DuPont Krytox is an inert lubricant designed originally as an aerospace lubricant suitable for many areas around the car including door seals, hinges and latches. The product can also be used between plastics to prevent squeaks (see list below of some applications). Unlike petroleum based products (silicon and lithium grease t0 name two common products) Krytox will not damage rubber products. Before applying to rubber surfaces they should be free of all contaniments and the use of a IMS (Industrial Marine Solvent) similar to 3M General Purpose Adhesive Cleaner and Wax Remover (part number 08984) is recommended.

Krytox comes in two package types from DuPont, an oil and a grease. Volkswagen sell both plus an aerosol, most auto manufacturers sell Krytox repackaged.

What is Krytox?

Krytox is a high-performance, non-flammable and chemically inert lubricant that is compatible with oxygen and has a strong resistance to aggressive chemicals. Krytox® provides extended life across a wide range of high-temperature applications.

Krytox oil is a perfluorinated polyether. It is a liquid fluoropolymer, similar to liquid Teflon®. Greases are made with various viscosity grades of PFPE oil that are thickened with special PTFE grease thickeners to match the performance capabilities of the oils. Various additives for corrosion protection, extreme pressure conditions, or antiwear improvement are added to some of the grades.

Krytox is compatible with all seal materials. It is chemically inert.

Krytox is a very safe lubricant to use. All Krytox products are chemically inert. Krytox oils are even used in cosmetics and the greases as barrier creams. The materials decompose at temperatures above 343°C (650°F); some of the decomposition products are potentially hazardous.
Krytox does not contain any Volatile Organic Compounds. Krytox® is made of fluorine, oxygen, and carbon. It does not contain any hydrogen.
