Purpose and Specifications

Liqui Moly Pro-Line Silicone Spray 7389 (400ml tin) is a clean, silicone-based lubricant that protects rubber, plastic, metal, and wood parts without staining or attracting dirt. It eliminates squeaks and creaks, insulates against moisture, and provides long-lasting wear protection for car interiors and exteriors. Safe for use from -50°C to +200°C, keeping parts flexible in freezing winters or hot engines. Reapply every 6-12 months or 10,000-20,000 km for optimal performance; shelf life is 5 years unopened.

When to Use / Replace?

• Use on door seals, weatherstripping, hood latches, seat tracks, plastic trim, and rubber hoses to stop sticking, cracking, or noise.
• Ideal for assembly aids on O-rings and belts where oil or grease would mess up paint or finishes.
• Replace treatment when squeaks return or parts dry out, typically every 6 months in harsh weather or 10,000 km in daily drivers.
