Automotive Interior NVH Product Line: eliminate interior noise once and for all.
Krytox™ long-lasting, high-performance lubricants help you deliver the quiet ride today’s drivers demand. Offering onceand-done lifetime lubrication, broad material compatibility, and non-migrating properties, the portfolio of Krytox™ fullysynthetic perfluoropolyether (PFPE) oils and greases contain the perfect solution for eliminating noise generated from friction or vibration between any components and materials in the vehicle cabin.
Choose the Krytox™ high performance lubricant solution that’s right for you.
The following diagram and table detail the specific interior applications, properties, and benefits of our Krytox™ lubricants for NVH and BSR issues, so you can select the solution that meets your challenges. From sunroofs and cup holders to gear shifters and brake pedal assemblies, our variety of high-performance lubricants tackle NVH (noise, vibration, and harshness) and BSR (buzz, squeak, and rattle) throughout the vehicle—even in the most extreme conditions—ensuring a luxury ride every time.
Where do Krytox™ lubricants outperform? Everywhere.
Application-specific product recommendations
| Application | Recommended Product | Characteristics | Benefits |
| Weather Stripping & Seals | |||
| Elastomer body seals Door, hood, and trunk seals, requiring excellent surface wetting, low volatility,and prevention of NVH or stick-slip issues |
Krytox™
AUT U14 |
Low-viscosity,
colorless oil |
Krytox™ AUT U14 is specially
formulated to reduce stick slip on elastomer surfaces. Superior properties include excellent surface wetting, washout resistance, and non VOC. Contains UV indicator |
| Sunroof weather stripping Elastomer seals with exterior exposure, requiring stick-slip reduction and resistance to contamination and washout |
|||
| Exposed Interior Surfaces | |||
| Headrest posts Exposed sliding contacts between metal and plastic require lifetime lubrication, NVH prevention, and broad useful temperature range |
Krytox™ GPL 105
|
Medium
viscosity, colorless oil |
Krytox™ GPL 105 is used
for applications requiring lifetime lubrication. Key benefits include wide temperature lubrication, low volatility, and low migration |
| Interior surface NVH Prevention of NVH and stick-slip caused by close contact of unlike materials, including synthetic leather, ABS, and PC-ABS |
|||
| Seatbelt mechanism Safety system requiring lifetime lubrication over wide temperature range to maintain easy user operation |
|||
| Sun visors Contacts between plastic and metal requiring lifetime lubrication and broad useful temperature range |
|||
| Gears, Springs, Hinges, & Latches | |||
| Air bag spring Safety systems requiring lifetime lubrication with consistent viscosity over specified use temperatures |
White, PTFE
thickened grease with creamy consistency (NLGI Grade 2) |
Krytox™ GPL 205 benefits
include no-VOC, low volatility, broad material compatibility, and excellent lubrication properties across wide-use temperatures |
