Reliable Sealing for Your Fuel System

Fuel leaks around the needle and seat assembly can cause dangerous fire hazards and inconsistent fuel levels. The Advanced Engine Design Nylon Needle & Seat Gaskets are designed to provide a reliable, leak-proof seal for your Holley carburetor. These gaskets are precision-cut to the correct thickness and diameter, ensuring that your float levels remain accurate and your fuel system stays pressurized.

Why Use Nylon Gaskets?

  • Superior Sealing: Nylon provides excellent compression to seal uneven surfaces.
  • Chemical Resistance: Compatible with various fuel types, including pump gas and race fuel.
  • Perfect Fit: Designed with a 0.25 in / 0.375 in ID and 0.031 in thickness for universal Holley fitment.
  • Durable Construction: Resists degradation over time, maintaining a tight seal.

Never reuse old, flattened gaskets when servicing your carburetor. Fresh gaskets are the cheapest insurance against fuel leaks and performance issues. These high-quality nylon seals are a must-have for any mechanic’s toolbox, ensuring that your carburetor rebuild is done correctly the first time. Trust in the quality and precision of components sourced from GGCRACING.
