Seal Cracking Failure Root Cause Analysis

Challenge

A critical NBR seal failed prematurely by cracking during service, resulting in significant leakage. The customer needed to understand the failure mechanism to prevent recurrence.

Results

Employed DSC for thermal property assessment and TGA for compositional analysis. Compared cracked and reference seal specimens to identify differences. SEM-EDX was used for contamination screening.

Approach
