The leak repair experts.

Colt technicians have repaired thousands of transformer oil leaks using our proven injection process. The repairs are completed while the leak is active and in many cases are done with the unit energized. After the sealant has been hydraulically injected, the injectors (shown left) are removed and Teflon coated pipe plugs are installed. The proprietary, two-part rubber like sealant will not bond to the flanges and maintains a "memory" that allows the sealant to expand and contract as needed due to temperature changes and vibration. This sealant has excellent dielectric properties and has had dissolved gas analysis completed. Our standard two-year guarantee is provided.
