Federal Mogul VS 50776 R Valve Stem Seal Set

The Federal Mogul VS 50776 R is a valve stem seal set engineered to restore proper oil control at the valve stem-to-guide interface. Manufactured by Federal Mogul — a globally recognized leader in engine sealing technology — this set delivers OE-quality performance and long-term durability for professional engine rebuilds and repairs.

Valve stem seals play a critical role in preventing engine oil from migrating down the valve stem and into the combustion chamber. Worn or cracked seals commonly result in blue exhaust smoke, increased oil consumption, fouled spark plugs, and elevated emissions. Replacing the valve stem seals with a quality set like the VS 50776 R helps restore proper engine sealing and oil control.

Key Features:

• Direct OE replacement fit — no modification required
• High-quality rubber compound construction for heat and chemical resistance
• Precision-molded for consistent sealing force on the valve stem
• Engineered to maintain seal integrity under high-temperature engine operating conditions
• Complete set covering all valves for a full valve stem seal service
• Manufactured by Federal Mogul to meet or exceed original equipment specifications

The VS 50776 R valve stem seal set is the trusted choice for engine rebuilders and professional technicians seeking a reliable, cost-effective solution for valve train oil sealing.
