Nozzle Jet Brass 0.42 Each

The Nozzle Jet Brass 0.42 Each by ENDERLE is a precision fuel system component engineered for high-performance engines requiring exact atomization control. Built to OEM specifications, this brass nozzle jet serves critical roles in carburetor and fuel injection systems where metering accuracy directly impacts combustion efficiency and engine responsiveness. Whether you're maintaining a vintage racing engine, restoring a classic vehicle, or tuning a high-output power plant, selecting the correct jet size—in this case, 0.42—is fundamental to proper fuel-air mixture calibration.

Machined from durable brass, the Nozzle Jet Brass 0.42 Each features precision orifice geometry that regulates fuel flow with tight tolerances—critical for maintaining stable idle, mid-range response, and wide-open throttle performance. The 0.42 designation refers to the jet orifice diameter in millimeters, a standard ENDERLE specification that controls fuel volume delivery to the engine. Brass construction resists corrosion from fuel additives and ethanol blends while providing excellent machinability for custom tuning applications. The compact 1.55 x 0.5 x 2.95-inch profile integrates seamlessly into most carburetor bodies and fuel manifold assemblies without requiring adapter modifications.

Carburetor builders, engine tuners, and mechanical fuel system specialists rely on ENDERLE jets to dial in precise air-fuel ratios across RPM ranges. The 0.42 size suits mid-displacement applications and moderate boost levels where stock fuel delivery requires fine-tuning. Installation is straightforward—most nozzle jets press or screw into carburetor bodies or fuel rails with standard hand tools. Before ordering, verify your carburetor model number or fuel system schematic to confirm the 0.42 jet is the correct size for your application; incorrect jet sizing can result in lean running, hesitation, or rich conditions affecting drivability and engine longevity.
