11mm O-ring | 92.8 (Brown)

The 11mm O-ring is used to create a secure, leak-free seal between the fuel injector and the fuel rail or intake manifold. It ensures proper fuel containment under high pressure, preventing vacuum leaks and fuel seepage that can affect engine performance.

The brown 92.8 O-ring refers to its high-durometer hardness rating, which provides superior resistance to fuel pressure, heat, and deformation. This makes it ideal for high-performance and racing fuel systems operating under extreme conditions.

Yes, this 11mm O-ring is compatible with E85, ethanol blends, race fuels, and standard gasoline. Its fuel-resistant compound prevents swelling, cracking, or degradation commonly caused by high-ethanol fuels.

Yes, the 11mm 92.8 brown O-ring is designed to fit Injector Dynamics injectors that require an 11mm seal. It ensures proper alignment and consistent sealing for both OEM and aftermarket fuel rail setups.

Injector O-rings should be inspected during every injector removal and replaced whenever signs of wear, flattening, cracking, or fuel seepage appear. Using fresh 11mm O-rings ensures optimal sealing, protects against vacuum leaks, and maintains safe fuel system operation.
