What are the exact dimensions and why do they matter?

These RARAYC drain plug gaskets measure 0.82 inch (outside diameter), 0.47 inch (inside diameter), and 0.07 inch thickness. Correct outer and inner diameters ensure the washer compresses properly around the drain plug thread and seats flat against the oil pan. Using the right size prevents over-compression or incomplete sealing that can cause oil seepage.

• Outside diameter: 0.82 inch for secure pan contact
• Inside diameter: 0.47 inch to fit drain plug shaft
• Thickness: 0.07 inch for predictable crush behavior
• Replace at each oil change for consistent sealing

How do I install these crush washers correctly?

Installation is straightforward: remove the old washer, clean the mating surfaces, slide the new aluminum washer onto the drain plug, and torque the plug to the vehicle manufacturer's specification. The washer is single-use—when the bolt is tightened the aluminum deforms slightly to form the seal, so reuse is not recommended. Proper torque avoids damaging the oil pan or over-crushing the washer.

• Remove old washer and clean oil pan seating area
• Place new RARAYC washer on drain plug before inserting
• Tighten to factory torque — do not overtighten
• Replace washer after every oil drain for best results

Who is this for?

This 100-piece pack is ideal for DIY enthusiasts, home mechanics, small repair shops, and fleet operators who perform frequent oil changes on Toyota, Lexus and Scion vehicles. It offers a cost-effective supply for regular maintenance, ensuring you always have the correct size crush washer on hand. If you manage multiple vehicles or prefer replacing the washer every service, this bulk set eliminates the need for repeated parts orders while providing consistent, OEM-style sealing performance.
