AULDAY Aluminum Oil Drain Plug Gaskets for Toyota/Lexus/Scion — 100-Pack Crush Washers 0.82" OD

AULDAY 100-piece aluminum oil drain plug gasket set replaces Toyota/Lexus/Scion part numbers like 90430-12031 to provide reliable crush washer seals for routine oil changes.

Whether you’re a DIY mechanic, a professional technician, or a fleet manager, these replacement crush washers are sized and specified to match many Toyota, Lexus and Scion applications. The kit contains 100 aluminum washers designed to compress and seal the oil drain plug, reducing the risk of leaks after oil service. Each washer is manufactured from high-quality aluminum combined with non-asbestos material, inspected for consistency, and sized to the dimensions commonly used across popular models.

Will these gaskets fit my vehicle?

These crush washers are compatible with a wide range of Toyota, Lexus and Scion models when the OEM drain plug uses the same size and crush-style sealing surface. They replace OEM numbers such as 90430-12031 and several close variants, making them suitable for many engines that accept a 0.82" OD aluminum washer.

• Direct OEM replacements: 90430-12031, 90430-12018, 90430-C0005 and similar.
• Common fitment: Avalon, Camry, Corolla, Tacoma, 4Runner, RAV4, Prius, Tundra, Sienna, Highlander.
• Check: outside diameter 0.82", inside 0.47", thickness 0.07" before installation.

How do these aluminum crush washers perform during an oil change?

The crush washer compresses between the drain plug head and the oil pan surface, forming a tight seal that helps prevent drips and leaks. Aluminum washers are soft enough to deform slightly for a custom fit at installation yet durable enough to withstand oil and heat exposure in normal service intervals.

• Soft-metal sealing: designed to deform for a leak-free contact.
• Oil- and heat-compatible materials for routine engine temperatures.
• Single-use design: replace at each oil change for best sealing.

Why buy a 100-piece kit instead of single washers?

Buying in bulk saves time and cost—especially for shops, enthusiasts who perform frequent maintenance, or fleet servicing multiple vehicles. With 100 pieces on hand you avoid last-minute trips to the parts store and ensure consistent, OEM-size replacements for many service cycles.

• Cost-effective: lower cost per gasket compared with singles.
• Convenience: ample supply for multiple oil changes or vehicles.
• Consistency: all washers made to the same size and tolerance standards.

What quality assurances and warranty come with the gaskets?

AULDAY inspects each gasket before shipment and backs the set with a 12-month warranty plus lifetime technical support for fitment questions. If you experience manufacturing defects or have compatibility concerns, the seller offers assistance to resolve the issue.

• Factory-tested parts for consistent sizing and finish.
• 12-month warranty covers defects; lifetime technical help available.
• Clear return/support channels if a part does not match your application.

Who this is for: This 100-piece AULDAY oil drain plug gasket pack is ideal for home mechanics who change oil regularly, independent repair shops, service fleets, and Toyota/Lexus/Scion owners who prefer stocking OEM-style crush washers. Confirm your vehicle’s OEM part number or measure the drain plug gasket seat (0.82" OD, 0.47" ID, 0.07" thick) to ensure compatibility before purchase. These washers are intended as single-use crush washers and help keep drain plugs leak-free between services when installed correctly.
