The O-Ring Carb Nut Tall 1/4-20 by ALLSTAR PERFORMANCE is a precision carburetor fastener designed for serious engine builders and performance mechanics. This specialized component secures carburetor bowls and fuel system assemblies, providing reliability in high-vibration environments common to racing and modified street engines.
The tall design accommodates thicker gasket stacks and complex fuel delivery systems, making it essential for custom carb mounting and tuning applications. Built with a 1/4-20 thread pitch, this fastener features an integral O-ring seal that eliminates the need for separate washers or gaskets in fuel-critical applications, reducing the risk of leaks.
Carburetor enthusiasts upgrading Holley, Edelbrock, and vintage Rochester carburetors will find this nut particularly beneficial. Its sealed design is advantageous for mechanics working on naturally aspirated or supercharged engines, ensuring torque spec consistency is maintained for optimal performance.
