|
Transmission pan gasket users were dissatisfied with the high cost of rubber-onsteel overmolded gaskets. In thermal cycling tests, the test gaskets failed in under 265 hours due to delamination around bolt holes and stress relaxation.
|
A Select-a-Seal gasket, combining compression and adhesion, easily passed a customer mandated 1000- hour thermal cycling test, and exceeded the customer's requirement by 2.5 times (at which time the test was suspended). |
Test Cycle:-40°C to 150°C Continuous Cycle, 4 hours total (6 complete cycles per day) 2 psi continuous ATF pressure, static charge non-circulating
- Lower unit cost
- Eliminated field complaints
- Improved customer satisfaction
