Weber Air Corrector Jet 77401 - Size 165
The Weber Air Corrector Jet 77401 is a precision-manufactured brass carburetor component designed for optimal engine performance. This size 165 jet features a calibrated orifice that corresponds to a 1.65mm flow rate, following Weber's sizing nomenclature where the number represents flow rate in hundredths of a millimeter.
Key Features:
- Precision Machined Brass Construction: Made from high-quality brass material for durability and corrosion resistance
- Flow Tested: Each jet is individually calibrated and flow tested to ensure consistent performance
- Size 165 Specification: Provides specific air flow characteristics for mixture control
- Professional Grade: Manufactured to original Weber specifications
Compatibility:
This air corrector jet is compatible with multiple Weber carburetor models including:
- Weber DCOE (40/45mm)
- Weber IDF (40/44/48mm)
- Weber IDA (46/48mm)
