Sonnax automatic transmission valve body check ball

Size: .250"

Quantity: 10 pack

Benefits:

• Better check ball seal
• Eliminate separator plate wear from steel balls
• Eliminate elastomer rubber check ball wear

The new Sonnax check balls 10000-08 (.250") are made out of tough, wear- resistant iridized plastic. The Sonnax iridized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel check balls are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar iridized plastic balls have been used on some original equipment late model valve bodies with excellent results. These iridized plastic check balls are not available through the original manufacturer.
