Moroso 97010 drain plug washers provide a reliable, leak-free seal for oil pans, transmission pans, and differential covers. These professional-grade washers are manufactured from dead soft copper, which conforms perfectly to sealing surfaces and crushes evenly under torque to create an optimal seal.

Key Features:

• Dead soft copper construction for superior sealing performance
• 1/2 inch inner diameter x 7/8 inch outer diameter
• Ensures leak-free seal on oil drain plugs and other fluid drain applications
• Conforms to sealing surfaces for maximum reliability
• Includes ten washers per package

These crush washers are designed for one-time use and should be replaced each time a drain plug is removed. The soft copper material prevents damage to aluminum and steel drain pans while providing a secure seal that withstands high temperatures and pressure. Ideal for engine oil changes, transmission service, and differential maintenance on automotive, racing, and performance applications.
