Description
Product Overview
The SeaEagles Carburetor Needle Seat Gasket Kit is engineered specifically for Holley carburetors ranging from the 2300 to the 4500 series. Each kit contains twenty precision‑cut gaskets: ten bottom gaskets (part number 1008‑778) and ten top gaskets (part number 1008‑777). Crafted from a high‑temperature resistant composite, the 1.5 mm thick material maintains its shape under combustion heat, preventing the common issues of crumbling, tearing, or fluid leakage that can compromise fuel metering. The compact package measures 2.64 × 2.09 × 0.47 inches and weighs just 0.317 oz, making storage and handling effortless. Designed for a seamless fit, the gaskets align perfectly with the needle and seat bores, delivering a uniform seal that supports consistent airflow and fuel delivery.
Usage
This gasket kit is ideal for both professional mechanics and DIY enthusiasts performing a carburetor rebuild on classic muscle cars, street‑legal hot rods, or race‑prepared machines. Install the bottom gaskets first, followed by the top gaskets, to restore the needle and seat assembly to factory specifications. The kit works in a variety of environments—from a well‑equipped garage with torque wrenches and precision tools to a mobile pit lane where quick, reliable service is essential. By using SeaEagles gaskets, users can expect reduced fuel leakage, improved throttle response, and a more stable idle, which translates to better overall engine performance.
