AULDAY Oil Drain Plug Gaskets for Toyota Lexus Scion — 100PCS Aluminum Crush Washers, Non-Asbestos Seal

AULDAY 100PCS oil drain plug gaskets are aluminum crush washers engineered to seal drain plugs on many Toyota, Lexus and Scion engines to prevent oil leaks after maintenance.

These replacement crush washers (also called drain plug gaskets) come in a bulk pack of 100 and match common OEM reference numbers such as 90430-12031 and related variants. Made from aluminum with a non-asbestos seal layer, the washers are sized and tested to fit a wide range of Toyota-family vehicles so you can change gaskets every oil service without hunting for single pieces.

Which vehicles and engine types do these gaskets fit?

These gaskets are designed for many Toyota, Lexus and Scion applications across sedans, SUVs and trucks. Fitment covers models like Camry, Corolla, Tacoma, 4Runner, RAV4, Prius, Highlander, Tundra, Avalon, Sienna, FJ Cruiser and Scion TC, plus similar engines that use the listed OEM numbers.

• Replaces OEM numbers: 90430-12031, 90430T0024, 90430-12018, 90430-C0005, 90430-12027 and equivalents.
• Works on common Toyota oil drain plug sizes; verify your OEM reference before purchase.
• Bulk 100-pack supports multiple oil changes or a professional shop supply.

How are these gaskets built and what are the key dimensions?

Each washer uses an aluminum body combined with a non-asbestos sealing layer to create a crush-type gasket that deforms to fill gaps at the drain plug interface. They’re manufactured and inspected to maintain consistent thickness and diameter for reliable sealing.

• Outside diameter: 0.82 inch (≈20.8 mm).
• Inside diameter: 0.47 inch (≈12.0 mm).
• Thickness: 0.07 inch (≈1.8 mm).
• Aluminum construction for corrosion resistance and predictable crush behavior.

When should I replace the oil drain plug gasket, and how easy is installation?

Replace the crush washer every time you remove the drain plug to ensure a reliable seal; reusing an old gasket often causes leaks. Installation is straightforward—position a new gasket against the drain plug, thread the plug by hand to seat the washer, then torque to your vehicle’s specified value.

• Recommended: swap at every oil change for leak prevention.
• Hand-start the plug, then torque with a calibrated wrench to OEM spec.
• Bulk pack reduces downtime by keeping spares on hand.

If you need assurance after purchase, AULDAY provides a 12-month warranty and lifetime technical support for fitment or installation questions. Quality checks are performed before shipping to minimize defective items.

Who is this for? Mechanics, home DIYers and fleet owners who service Toyota-family vehicles will benefit from this 100-piece kit. It’s ideal for anyone who prefers to replace the crush washer every oil change—shops save time and buyers avoid leak-related rework by keeping a ready supply of correctly sized aluminum drain gaskets.
