4150 Carb Gasket w/Open Plenum .047 thick

The 4150 Carb Gasket w/Open Plenum .047 thick by Cometic Gaskets is a precision-engineered sealing component designed for high-performance carburetor installations. This gasket serves as the critical seal between your carburetor body and intake manifold, preventing fuel and air leaks that compromise engine efficiency and driveability. Whether you're building a street machine, vintage hot rod, or performance-oriented classic car, a quality carburetor gasket is essential for reliable operation and consistent fuel delivery.

This Cometic gasket features a .047-inch thickness that provides optimal compression and durability under thermal cycling and fuel exposure. The open plenum design accommodates standard 4150-pattern carburetors, allowing full atmospheric pressure entry into the intake tract for improved volumetric efficiency. Cometic's gasket materials are designed to resist fuel degradation, oil contamination, and temperature extremes, reducing the likelihood of mid-drive failure or vacuum leaks that can cause stumbling and poor idle quality.

Mechanics and engine builders rely on Cometic gaskets for carburetor rebuilds, engine swaps, and custom intake manifold applications where precision sealing is mandatory. This gasket is essential when upgrading to an aftermarket carburetor or re-sealing an existing 4150 installation after years of service. Proper installation requires a clean mating surface and even torque to ensure optimal performance.
