The Nylon Needle & Seat Washers (10pk) from Advanced Engine Design are precision gasket components designed for carburetor fuel delivery systems. These washers form a critical seal between the needle valve and seat, preventing fuel leakage and ensuring consistent fuel pressure regulation. They are essential for serious engine builders and mechanics who require OEM-grade replacement parts to avoid issues like flooding and poor fuel delivery tuning.
These nylon washers are engineered to create a watertight seal without restricting fuel flow. The nylon material resists fuel swell and chemical degradation over time, making them a superior choice compared to aged cork or composite gaskets. With dimensions of 0.25 inches inner diameter, 0.375 inches outer diameter, and 0.031 inches thickness, they are designed for optimal performance in carburetor applications.
Technicians restoring various carburetors, including Holley models, will find these washers invaluable for rebuilding fuel bowls and float assemblies. The 10-pack quantity allows for multiple rebuilds or provides spares for critical race season prep. Whether performing a complete carburetor overhaul or replacing worn needle seats, these washers ensure precise metering and repeatable performance.
