Federal Mogul VS 50504 R-1 Fel-Pro PermaDry Valve Cover Gasket Set

The Fel-Pro VS 50504 R-1 is a complete valve cover gasket set engineered specifically for the repair environment, delivering a reliable, leak-free seal even on imperfect or worn sealing surfaces. Manufactured by Federal-Mogul under the trusted Fel-Pro brand, this set utilizes a proprietary PermaDry molded rubber formulation that is highly conformable and built to withstand the repeated heating and cooling cycles that cause OEM gaskets to fail.

Key Features:

• PermaDry Molded Rubber Construction — Proprietary rubber material conforms to irregular and imperfect sealing surfaces for a superior, long-lasting seal
• Press-In-Place (PIP) Design — Retention tabs hold the gasket securely in the valve cover during installation for easier, faster repairs
• Includes Valve Cover Bolt Grommets — All necessary components for a complete repair are included in the set
• Meets or Exceeds OEM Specifications — Engineered and validated to deliver performance equal to or better than original equipment
• Real-World Tested — Parts are tested and validated on-vehicle to ensure optimal performance on the road
• No Sealant Required — Gasket material provides a complete seal without the need for additional sealant compounds

Valve cover gaskets are subjected to constant thermal stress, oil exposure, and mechanical vibration. Over time, this leads to compression set, cracking, and oil leaks. The Fel-Pro VS 50504 R-1 is purpose-built to address these real-world failure modes, making it the preferred choice of professional technicians and engine builders.
