A V2 +26mm Bottom Adapter for a 14mm Lower O-Ring Injector Interface
Injector Dynamics part number 34.60.14B is a V2 bottom adapter that adds 26mm of length below the injector body and terminates in a 14mm lower O-ring interface, finished in blue. Bottom adapters like this one change the injector's effective length and lower seal interface so a given injector body can seat correctly in a fuel rail or intake manifold it was not originally cut for. Confirm the injector model, fuel rail, and intake manifold dimensions against this adapter's +26mm length and 14mm lower O-ring before ordering.
Key Features
- V2 revision fuel injector bottom adapter that adds 26mm of length below the injector body
- Terminates in a 14mm lower O-ring interface for compatibility with matching injector or fuel-rail seats
- Blue finish, matching Injector Dynamics' color-coded adapter system
- Supplier-confirmed part number 34.60.14B

About Injector Dynamics
Injector Dynamics develops fuel-system components around published specifications and application data rather than generic marketing claims, and applies the same exact-configuration approach to its adapters, filters and pump systems that it uses for its fuel injectors.
FAQ
What does the +26mm dimension on this adapter describe?
Injector Dynamics' retailer-listed specification for 34.60.14B states that the V2 adapter adds 26mm of length below the injector body.
What lower interface does this adapter use?
A 14mm lower O-ring interface, per the supplier-listed specification for this exact part number.
Is this the V1 or V2 adapter revision?
V2, according to the supplier listing for MPN 34.60.14B.
What color is this adapter?
Blue, matching Injector Dynamics' color-coded adapter finishes.
Will this adapter fit any Injector Dynamics injector body?
No compatibility list by injector model is published for this exact adapter; confirm the injector's top and bottom interface against the +26mm length and 14mm lower O-ring before ordering.
Does this adapter include mounting O-rings beyond its own lower O-ring?
No packing list is published for this exact part number; order any additional seals separately unless confirmed otherwise.
Is vehicle-specific fitment documented for this adapter?
No. This is a fuel-system component classified as universal because no vehicle or engine application is published for it; it is compatible based on injector and rail dimensions rather than a specific vehicle.
Is a torque specification published for installing this adapter?
No torque value or installation procedure is published for this exact part number.
Where can injector O-ring retainer guidance be found?
Injector Dynamics publishes general guidance stating that the molded O-ring retainer on its injectors should only be removed on the manufacturer's instruction, because incorrect removal can cause catastrophic engine damage.
Installation Instructions
Injector Dynamics does not publish an installation procedure, torque value, or compatibility table for this exact adapter part number. The steps below are limited to general fuel-injector-adapter handling practice; confirm injector and rail compatibility before starting.
- Confirm the injector body's top and bottom interface dimensions match this adapter's +26mm length and 14mm lower O-ring before beginning disassembly.
- Depressurize and isolate the fuel system per the vehicle's factory service information before removing the fuel rail.
- Inspect the injector's existing O-rings and seats for wear or damage before fitting the adapter.
- Seat the adapter fully onto the injector body, verifying the 14mm lower O-ring is not pinched or twisted.
- Lightly lubricate O-rings per general fuel-injector service practice; do not use a lubricant incompatible with the fuel in use.
- Test-fit the adapted injector in the rail or manifold bore before final assembly to confirm the +26mm length seats correctly.
- Reinstall the fuel rail per the factory service information, torquing rail fasteners to the vehicle manufacturer's specification.
- Pressurize the fuel system and check for leaks at the adapter interface before starting the engine.
- Start the engine and recheck for leaks at idle and under load before returning the vehicle to service.
