Transformer Regasketing and Leak Repair

As transformers age, the original gasket material deteriorates and leaks can become visible at gauges, valves, radiator flanges, access covers and bushings. Additionally, if your transformer will no longer hold a positive pressure or if you are constantly changing nitrogen bottles you may have faulty gaskets on your unit.

Applying Epoxy to certain leaks can help for awihle but ultimately the best way to repair a leaking unit is to replace all the gaskets with modern material such as Buna-Nitrile and Viton depending on the application.
