Understanding Oil Crush Washers: Essential Components for Leak-Free Seals

When performing an oil change or replacing a drain plug, one crucial component often overlooked is the oil crush washer. This small but essential part ensures a proper seal, preventing leaks around the drain plug. The crush washer compresses under pressure, forming a tight, leak-proof seal between the drain plug and the oil pan. In this article, we’ll explore the importance of oil crush washers, including specific types like 12mm crush washers, drain plug washers, and where to find them, such as Crush Washer AutoZone.

What is an Oil Crush Washer?

An oil crush washer is a sealing component typically used in automotive and machinery applications to prevent oil leakage around the drain plug. Made of soft, malleable materials such as aluminum or copper, the washer is designed to compress as the drain plug is tightened. This compression creates a tight seal that helps prevent oil from leaking during or after the oil change process. Oil plug crush washers are commonly used in oil pans and various automotive components to ensure a secure, leak-free fit.

Common Types of Crush Washers

12mm Crush Washer

A 12mm crush washer is one of the most common sizes used in automotive applications. It is designed to fit drain plugs with a 12mm diameter, offering an ideal seal for engines and equipment that require this specific size. The 12mm crush washer is typically made of soft metal materials such as aluminum or copper, which provide excellent sealing properties while also being easy to replace.

Drain Plug Washer and Drain Plug Crush Washer

The drain plug washer or drain plug crush washer serves the same essential purpose—creating a leak-proof seal between the drain plug and the oil pan or reservoir. These washers are typically replaced during every oil change to maintain their sealing effectiveness. Over time, the washer compresses and may lose its sealing capability, so it’s essential to replace it with a new one each time the drain plug is removed.
