Targeted Leak Solutions

Stop Transformer Gasket Leaks Without Teardown

Leaking transformer cover and lid gaskets can contribute to oil loss and maintenance concerns. TDS begins with precise leak confirmation, then applies a repair method suited to the failed gasket or surrounding component. Cured-in-place gasket techniques and engineered sealing solutions can often avoid traditional disassembly, while repairs may be completed with apparatus energized and in service when conditions allow. Service is available for utility and power-generation equipment.
