NBR Float-Carburetors

In automotive applications, carburetors (primarily in classic/vintage vehicles) require precise air-fuel mixing for smooth ignition and drivability. Motorcycle carburetors demand compact, vibration-resistant designs that deliver responsive performance across RPM ranges, especially in off-road and cruiser models. For agricultural machinery (tractors, harvesters, mowers), carburetors must endure dusty environments, irregular operation, and handle varying fuel qualities while maintaining reliability.

Central to all these applications is NBR (Nitrile Butadiene Rubber), a material critical to carburetor functionality. NBR forms essential seals, gaskets, diaphragms, and O-rings within the fuel system. Its exceptional resistance to petroleum-based fuels, oils, and temperature fluctuations (-40°C to +120°C) prevents:

Fuel leaks ensuring safety and emissions compliance
Swelling/degradation maintaining calibration accuracy
Air ingress disrupting the fuel-air emulsion

Without high-grade NBR components, carburetors would suffer rapid failure from ethanol-blended fuels, thermal stress, and abrasive contaminants. We rigorously test our NBR formulations to guarantee 5,000+ hours of service life across all operating conditions. For engines relying on carburetion, NBR isn’t just a seal—it’s the foundation of dependable performance.
