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.

15 comments to DuPont Krytox lubricant – door seals, hinges, latches, squeaks and rattles

  • AdamGTIVI

    Uhhh! I bought the aerosol from VW as my GTI door rubbers are very creaky – what a waste!! The can is mostly air and after one application it was empty. Considering this is the second application in 4 months, I need something that will last more than one use so off to Fluid Seals. Here’s hoping the oil / grease are less costly and a bit more permanent!

    • Ian

      My GTI VI also has very creaky door seals. It sounds like lots of body flexing as it most pronounced when going slowly over very uneven surfaces such as entering a driveway. Car has had the issue since 300k and is now at 1500k. VW used Krtox on it but it seems to have made no difference.

      Is there another product which works?

      Is there an issue with body regidity?

      • kopite0055

        Ian, I just bought my gti mkvi and I am having the same issue.. have you fixed the problem yet??

        • Ian

          Door seal noise – yes fixed.
          I found the issue was not the rubber seals, but the felt strip that goes around the top of the door (above the rubber seals). Any movement caused much noise/creaking.
          $4.50 stick of dry lub purchased from any hardware store. Run this along the felt strip of all doors. Noise disappeared!

    Yeah my GTI had really squeaky door rubbers too when going over speed bumps etc. I sprayed the rubbers with rubber lubricant made by Rare Spares from memory that I bought from Autobarn (in Australia) which is just an automotive parts/accessories shop.

    Can was about $25 and it lasted me about 6-12 months.

  • Boon

    My brand new GTI is 6 motnhs old. It will be in the dealership the 4th time to “fix” squeaky door rubbers & the tick-tick-tick noise from B pillars “caused by sunlight” again. The dealership has been helpful & understanding, but let down badly by VW Australia. I have emailed VW Australia, but “no reply” for weeks now. After paying around AUD$50k for a brand new GTI… Do we have to suffer? Any class action due to VW’s design fault??

  • andy

    Ive been using a silicone spray for all my door seals for 3 years. No perished rubber and no wind noise.

  • Silvabak

    i’ve been using rp7. it needs re application about once a month, but anything to stop the damned squeak. the brand of silicon spray lube i have does not recommend its use for extended periods.

  • Kevin

    All ya need to do is put some anti squeak tape along the door frame where that felt piece rubs on the car. If it’s a 4 door, make sure that same felt strip isn’t touching the rubber piece from the back doors. My driver side door would squeak even from simple hard braking, small bumps, and even on the highways where the road “cracks” were! It drove me NUTS! (Oh, 2010 4dr gti) That’s what I ordered. Grab 2 rolls so you can hit both sides of the car.

  • Glenn

    Everyone, try a product called Gummiphledge by Einszett. It’s German, obviously, and is the only thing that all the german manufacturer’s like VW, Audi, Skoda, Mercedes use. Rids door squeaks instantly. Is conveniently available in a small bottle that has an applicator on the top (like those easy Kwik shoe cleaners with the sponge thingie on the top). Great product.
