Distribution Transformer Gaskets

Distribution transformer gaskets and sealing solutions designed to prevent oil leaks and moisture ingress, including nitrile, cork-rubber, and high-performance elastomer gaskets for utility, industrial, and commercial transformer applications. Gaskets are critical sealing components that maintain a leak-proof and moisture-resistant enclosure, preventing transformer oil loss and protecting internal insulation systems. Effective gasketing is essential because oil leakage can lead to overheating and failure, while moisture intrusion accelerates insulation breakdown and reduces transformer life. 

Parts Super Center offers a wide range of distribution transformer gaskets designed for tank covers, radiators, bushings, access plates, and valve connections, supporting both new installations and maintenance of aging transformer fleets. Our gasket solutions are engineered to maintain tight sealing under pressure, temperature variation, and long-term exposure to transformer oil and environmental conditions.

Built for Utility & Industrial Reliability our transformer gasket solutions are designed for electric utilities and substations, steel mills and heavy industrial facilities, commercial and institutional infrastructure, and renewable energy and grid applications. Proper sealing plays a vital role in maintaining transformer performance by preventing oil contamination, preserving dielectric strength, and extending equipment lifespan.

We supply gasket solutions for a wide range of transformer components, including:

• Tank cover and manway gaskets
• Radiator and cooling system gaskets
• Bushing and turret gaskets
• Valve, drain, and flange gaskets
• Tap changer and access plate seals

These gaskets are designed to conform to mating surfaces and maintain a durable seal even under vibration, pressure, and thermal cycling.
High-quality gasket materials must provide thermal stability, chemical compatibility with transformer oil, and long-term resistance to aging and environmental exposure.  We support sourcing and cross-referencing for gasket kits and individual seals compatible with major OEM transformer manufacturers, including ABB, Eaton, GE, Siemens, and Prolec.

Typical industry part number formats include:

• Transformer gasket kits: TGK-1000, TGK-2500, TX-GSK-SET series
• Tank cover gaskets: TCG-36x48, TCG-48x72, FLG-RECT series
• Radiator gaskets: RAD-GSK-24, RXF-GSK series
• Bushing and flange gaskets: BSH-GSK-200A, FLG-150LB formats
• OEM-style references: 5GKT, 7TK, 9TG series (GE / ABB style formats)

Whether you’re performing routine maintenance, re-gasketing aging equipment, or sourcing replacement components, our distribution transformer gaskets deliver the reliability and performance required to keep power systems sealed and protected.
