Why Oil & Petrol Sealing Washers Matter

Oil and petrol sealing washers are critical components in systems where even a minor leak can lead to catastrophic failure. Unlike standard washers, they are engineered to:

  • Resist Extreme Heat: Withstand temperatures up to 500°F (260°C) in engines and exhaust systems.
  • Block Chemical Corrosion: Compatible with oils, petrol, diesel, and hydraulic fluids.
  • Maintain Compression: Create airtight seals under high vibration and pressure.

Types of Oil & Petrol Sealing Washers

  1. Copper Crush Washers
  2. Aluminum Sealing Washers
  3. Metric & SAE Washers
  4. Composite Washers

Top Applications

  • Automotive Engines: Use "petrol sealing washers" on fuel rail connections and oil filters to prevent fluid leaks.
  • Hydraulic Systems: "Oil sealing washers" ensure leak-free operation in excavators and forklifts.
  • Marine Equipment: Saltwater-resistant washers protect boat engines and fuel lines.
  • Aerospace: Lightweight aluminum washers reduce weight in aircraft hydraulic systems.

How to Choose the Right Washer

  1. Material Compatibility
  2. Temperature & Pressure Ratings
  3. Size & Thickness

Installation & Maintenance Tips

  • Surface Prep: Clean mating surfaces to remove old gasket material.
  • Torque Control: Over-tightening can split copper washers—follow manufacturer guidelines.
  • Reuse Policy: Never reuse "copper crush washers"; composite washers may be reusable if undamaged.
