Klüber Isoflex PDP 65

High-performance synthetic long-term oil

The legendary oil for audio perfection.

Revive your vintage audio gear with the lubricant that powered the golden age of hi-fi. Originally developed for high-end cassette decks and sensitive consumer electronics, this specialized oil is the key to silencing friction and restoring smooth, precise operation. Its unique formula is perfect for sintered bronze bearings and other moving metal components, ensuring your classic equipment runs with the smooth, detailed performance it was engineered to deliver. Give your treasured electronics the care and precision lubrication they deserve.

Key performance features

The Isoflex PDP 65’s ester oil base delivers exceptional performance advantages over conventional lubricants:

• Exceptional Thermal Stability: Designed for applications subject to high thermal and static loads. It maintains stable performance across a wide service temperature range, from as low as −50∘C/−58∘F up to 100∘C/212∘F.
• Superior Viscosity-Temperature Behavior: Unlike mineral oils, the viscosity of Isoflex PDP 65 remains highly consistent across hot and cold extremes. This ensures sustained performance, reduced power consumption, and less performance drop-off.
• Maximum Durability: Its excellent oxidation and ageing stability mean fewer lubrication intervals and a reduced need for maintenance, resulting in a genuine long-term solution.
• Low pour point and high flash point
• Corrosion Protection: Provides reliable defense against rust and wear, extending the life of your valuable components.

Ideal applications

Klüber Isoflex PDP 65 is the preferred choice for precision and high-speed applications, including:

Precision and High-Speed Applications

Essential for minimizing wow and flutter (speed variations) and ensuring quick, reliable operation of fast-wind modes.

Guides, Plain Bearings, and Control Systems

Directly applies to the capstan, reel tables, and mechanical levers in the tape transport.

High-Stress Bearings

Important for components under continuous load, like the capstan motor bearings or gears supporting the reel tables, especially at elevated speeds during fast-wind operations.

Exacting Tolerance and Reliability

Crucial for the long-term, consistent operation of finely-tuned metal mechanisms common in quality audio equipment.
