#30CB. Torlon Check Ball, .250″, 10 per bag. The check balls (.250″) Sonnax #10000-08
Torlon Check Ball, .250″, 10 per bag. The new check balls (.250″) are made out of tough wear- resistant imidized plastic. The imidized 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. Fits 700R4, 4L60E, 200-4R, TH400 and 4L80E transmissions. Sold 10 per bag.
