Fuel injector O-ring adapter 14 to 16 millimetres is a precision-machined adapter sleeve for fuel systems, used to adapt injectors between different O-ring standards. The adapter allows 14 mm injectors to be fitted in 16 mm fuel rail or weld-in solutions, without the need for custom manufacturing or modification of the injectors.
The adapter is typically used in performance and motorsport setups where different injector types, fuel rails or custom intake solutions are used, and where correct fitment and sealing are essential for a stable fuel system.
It is CNC-machined for precise fitment, ensuring correct centring of the injector and optimal sealing at the O-ring. This reduces the risk of leakage and ensures stable operation under high fuel pressure.
Suitable for engine builds, tuning and custom fuel systems where flexibility in injector standards is required.
Supplied as a set of 2 adapters.
