Sealing washers

Sealing washers are used to create a tight connection in fluid systems where it is important to avoid seepage and leaks around bolts, fittings and connections. They are often seen together with banjo bolts, banjo eyes, oil lines, fuel systems, cooling systems and other installations where a metal seal is necessary to ensure proper sealing between two surfaces. When a banjo bolt is tightened correctly, the aluminium sealing washer is compressed and helps seal the joint so the system can operate safely and reliably.

Aluminium sealing washers are used especially in cars, motorsport and custom-built projects where higher demands are placed on durability, fitment and resistance to heat, pressure and fluids. They are an obvious choice for installation or service of oil and fuel systems, hydraulic connections and other technical solutions where the correct seal is crucial. This applies both to new builds, repairs and replacement of worn or deformed sealing washers.

At Qualitec, you will find sealing washers for customers who want a simple and effective sealing solution for tuning, motorsport and custom-built cars. They are small parts, but they have a major impact on the overall result. If you choose the right aluminium sealing washer in the correct size, you get a safer installation and a solution that is better suited for demanding use.

These aluminium sealing washers are especially suitable for our banjo bolts and banjo eyes. They ensure a very robust and tight joint that remains 100% sealed even at very high fuel or oil pressure. Remember that two sealing washers must be used for each banjo bolt.

Do not use ordinary copper washers for aluminium AN fittings, as copper and aluminium do not work well together and can cause corrosion on the aluminium.
