Aluminum O-Ring Washer Assortment Kit

Aluminum O-Ring Washer Assortment Kit

Designed for versatility in automotive and electrical assemblies, this Aluminum O-Ring Washer Assortment Kit pairs corrosion resistance with a strong bearing surface to protect fasteners and seal joints more reliably than rubber washers. Made from aluminum, these washers stay resilient under high temperature, cold weather, and humid conditions while delivering a tighter, more dependable seal.

Key features

• Material: aluminum with robust corrosion resistance suitable for harsh environments.
• Design and function: reduces friction between fasteners, prevents leakage, isolates vibration, and helps resist loosening or dispersion pressure. Provides a greater bearing surface to prevent pull-through and to evenly distribute load across the bolt or nut.
• Applications: ideal for automotive and electrical use—oil lines, hydraulic fittings, oil drains, sump plugs, and other fasteners requiring a stable, wide-bearing washer.
• Sizes: M4, M5, M6, M8, M10, M12, M14, M16, M20, M22, M24, M26 (twelve sizes total).
• Thickness: 1 mm, 1.5 mm, or 2 mm options to match load and sealing needs.
• Pack options: available in 20-piece or 50-piece packs to suit different project scales.
• Origin: Mainland China

How to choose: select the correct size range (M4–M26) and thickness (1, 1.5, or 2 mm) to match your fasteners and surface area. If you’re unsure about the size variety for your project, review the available options before placing an order to ensure you have the right combination for sealing, load distribution, and pull-through prevention.

Note: Due to the wide selection of sizes and quantities for this product, please carefully review the options before placing an order!
