Select-a-Seal Durability and Robustness Case Study
Transmission Shift Tower

Beaded Fiber Gasket

undefined

A Six Sigma project by a major transmission manufacturer found that seal problems traditionally were among the most common warranty items. A case in point involved warranty claims on a shift tower, which used a beaded fiber gasket.

After analyzing and testing fiber composite, Select-a-Seal, and rubberedge molded seals, the Select-a-Seal gasket provided the best combination of durability and reduced rework costs.
