O-Ring For Nozzles

The O-Ring for Nozzles (MPN 2397) is a critical replacement seal component designed specifically for Kinsler fuel injector nozzles. This rubber O-ring serves as a precision elastomer gasket that prevents fuel leakage at the nozzle interface, ensuring reliable fuel delivery and system integrity in high-performance fuel injection applications. Whether you're maintaining an existing fuel system or rebuilding injectors after extended service, this replacement O-ring is essential for restoring proper sealing and preventing costly fuel loss or performance degradation.

Constructed from durable rubber compound, this O-ring is engineered to withstand the thermal and chemical demands of fuel system operation, including exposure to gasoline and various fuel blends. The precise dimensions (1.65 x 0.3 x 3 inches) ensure proper fit and sealing at the nozzle connection point, creating a reliable barrier against fuel weeping and vapor escape. Kinsler's reputation for precision fuel system components means this O-ring meets strict dimensional tolerances and material specifications required for consistent performance in both carbureted and fuel-injected systems.

This replacement O-ring is ideal for technicians, engine builders, and performance enthusiasts performing fuel injector maintenance, repair, or complete system overhaul. Installation is straightforward—the O-ring seats at the nozzle body interface to eliminate fuel seepage and maintain system pressure. For anyone using Kinsler fuel injector nozzles in racing engines, marine applications, or high-performance builds, keeping spare O-rings on hand ensures minimal downtime and consistent fuel delivery. Each ring is sold individually, so quantity can be adjusted based on your injector count and maintenance schedule.
