This aluminum flange is an evolution of nylon flanges, designed to improve reliability and prevent certain deformations related to use and high temperatures.
Mounting flange for a Weber carburetor on an intake manifold or intake pipe that does not have O-rings or connecting elements.
Provides a better seal and greater flexibility between the carburetor and the intake manifold. This isolates the carburetor from engine vibrations to prevent disturbing the settings.
Spacer sold separately with two O-rings (Two kits required per carburetor)
