Gasket Sealing Compounds

The appropriate sealant depends on the equipment, leak location, operating conditions and the media being contained. TDS Gasket Sealant Compound is formulated for substation apparatus and is described as compatible with transformer oil and SF6 gas. It is intended for gasket failures, flange leaks, valve packing repairs and related electrical equipment leak-sealing applications.

Gasket sealer can stop a leak when the compound, repair method and equipment conditions are suitable. TDS uses the compound for transformer flange leaks, bushing flange leaks, drain valve leaks, valve stem packing repairs, pinholes, weld seam cracks and circuit breaker leaks. TDS personnel assess the leak and apply the compound to the affected area.

The best gasket material depends on the equipment, fluid, pressure, temperature and joint design. For the applications listed by TDS, the Gasket Sealant Compound uses a compressible, rubber-based formula designed for oil resistance and in-place curing. Technical assessment is appropriate before selecting a material for a specific transformer, valve, flange or other apparatus.

The compound is used for gasket and packing leak repairs on electrical substation apparatus. Listed applications include transformer pipe flanges, bushing flanges, drain valves, four-bolt flapper valve stems, eight-bolt butterfly valve stems, pinholes, weld seam cracks and circuit breakers. These applications support repair work across power transmission and distribution facilities.

Yes. TDS identifies the compound as suitable for injection through a hydraulic gun into failed packing areas. It cures in place as replacement gasket material and is intended to match OEM gasket properties and life expectancy. The repair approach can avoid traditional apparatus dismantling when the equipment and leak conditions permit.

TDS states that its gasket sealing approach can allow repairs while equipment remains energised and in service. Whether this is appropriate depends on the apparatus, leak location, safety requirements and site conditions. TDS technicians evaluate the repair scope and method for equipment such as transformers, circuit breakers and other substation apparatus.
