PG Front Pump Seal

The PG Front Pump Seal from FTI Performance is a direct-replacement rubber seal engineered for automatic transmission systems in Powerglide-equipped vehicles. This component serves as a critical barrier between the transmission fluid and the external environment, preventing leakage at the front pump assembly where shaft rotation creates continuous mechanical stress. Whether you're rebuilding a vintage muscle car, restoring a classic truck, or maintaining a high-performance drag racing platform, this seal is essential for reliable transmission operation and fluid retention.

Manufactured from durable elastomer material, the PG Front Pump Seal is designed to withstand the thermal cycling and hydraulic pressure inherent in automatic transmissions. The seal's compact dimensions (3.95 x 0.55 x 5 inches) allow precise fitment around the front pump shaft, creating a dynamic seal that accommodates minor shaft runout while maintaining consistent contact pressure. FTI Performance's engineering ensures compatibility with original equipment specifications, allowing the seal to function effectively across a wide range of transmission fluid viscosities and operating temperatures without premature deterioration or leakage.

Mechanics and transmission specialists choose this seal for Powerglide units in street cars, race vehicles, and restorations where fluid integrity and long-term reliability are non-negotiable. Installation requires basic mechanical skills and minimal downtime—the seal simply replaces the original during front pump service or complete transmission rebuild. Keep this component on hand as preventive maintenance; front pump seal failure often goes unnoticed until transmission fluid loss becomes critical. Each seal (SKU FTIF2578) ships individually, making it easy to stock for single repairs or fleet maintenance programs.
