Kluber Barrierta L 55/3 - Extreme Performance Grease for Vacuum & High Heat (800g)

The Ultimate Lubricant for Mission-Critical Applications

In environments where lubricants are exposed to extreme temperatures, aggressive chemicals, or high vacuum, standard greases disintegrate. For these applications, you don't need a lubricant; you need an engineering marvel. Kluber Barrierta L 55/3 is precisely that—the global benchmark for reliability under the most severe conditions.

Built on a foundation of Perfluorinated Polyether (PFPE) oil and thickened with Polytetrafluoroethylene (PTFE), this is the ultimate PFPE Vacuum Grease. Its inert chemical nature and exceptional thermal stability ensure it performs flawlessly where others would have already failed, making it the definitive choice for industries where uptime and safety are paramount.

Key Features & Benefits:

• Unmatched Thermal & Chemical Stability: As a leading Chemical Resistant Grease, Barrierta L 55/3 is virtually inert. It does not react with most chemicals, aggressive gases, or concentrated acids and bases, ensuring it stays in place and provides continuous protection.

• Ideal for High Vacuum & Cleanrooms: The extremely low vapor pressure of the PFPE base oil prevents evaporation and outgassing. This makes it the perfect choice for high vacuum systems, semiconductor manufacturing, and cleanroom environments where contamination is unacceptable.

• Superior Sealing & Load-Carrying (NLGI 3): The firm NLGI Grade 3 consistency provides an excellent sealing effect, protecting bearings and components from the ingress of aggressive media and contaminants. This stiffness also ensures it stays in place under high loads and vibration.

• Extended Component Life & Reduced Maintenance: The legendary long-term stability of the BARRIERTA series allows for significantly extended relubrication intervals, or in many cases, true lifetime lubrication. This is a direct investment in reducing maintenance costs and maximizing operational uptime.

Primary Applications:

Kluber Barrierta L 55/3 is the trusted solution for the most demanding applications across various high-tech industries:

• Semiconductor & Electronics: Vacuum pumps, wafer handling robots, and cleanroom equipment.

• Aerospace & Defense: Actuators, instruments, and oxygen systems.

• Chemical Processing Industry: Valves, fittings, pumps, and seals exposed to aggressive chemicals.

• Instrumentation & Medical Technology: Bearings and sliding parts in scientific and medical instruments.

• High-Temperature Ovens: Bearings operating under extreme heat where a firm grease is required for sealing.

When failure is not an option and performance cannot be compromised, Kluber Barrierta L 55/3 is the only answer.
