Purpose and Specifications

The WD-40 WD-403FLEX is your go-to universal lubricant in a convenient 400ml aerosol can with a flexible straw for pinpoint application in tight spots. This premium WD-40 Multi-Use Product penetrates rust and corrosion to free stuck bolts, hinges, chains, and locks, while displacing moisture from engines, tools, and spark plugs. It lubricates moving parts like wheels, gears, and door hinges for smooth operation, protects metal surfaces from rust in humid or salty conditions, and cleans off adhesives, grease, and grime without attracting dirt.

Practical specs include operation from -23°C to 93°C (-10°F to 200°F), making it reliable for cold winters and hot engines. The thin film provides short-term lubrication lasting weeks on high-use parts; reapply every 1-3 months or 5,000-10,000 km on vehicles depending on exposure. Shelf life is 5+ years when stored cool and dry. Net weight 0.46kg, EAN 5032227476882.

When to Use / Replace?

• Use on squeaky hinges, rusted nuts/bolts, seized valves, or waterlogged tools to restore function instantly.
• Spray on bike chains, garage door rollers, or lawnmower parts to prevent rust and ensure easy movement.
• Reapply when parts start sticking again, typically every 1-2 months for outdoor exposure or after washing vehicles.
• Avoid long-term heavy lubrication; switch to WD-40 Specialist PTFE for chains/gears needing months of protection.
