Nozzle Holder Seal – Excellent Genuine Toyota Replacement
Maintain factory-level reliability with this Nozzle Holder Seal Set designed for 1HD-FTE and 1HD-FT Toyota LandCruiser diesel engines. Each set contains six genuine Toyota nozzle holder seals (23681-17010), providing the perfect replacement for worn or damaged injector seals.
These seals are an essential maintenance item whenever injectors are removed, serviced, or replaced. Installing new seals helps prevent combustion gas leakage, ensures proper injector seating, and maintains consistent fuel pressure within the cylinder head.
Why Replace Your Nozzle Holder Seals
Over time, heat cycling, fuel exposure, and age can harden or deform injector seals. Even a slight imperfection can lead to compression leaks, poor fuel economy, and loss of performance.
For these reasons, Toyota recommends replacing the nozzle holder seals whenever injectors are refitted — whether during a major service, engine rebuild, or injector reconditioning. It’s a small investment that protects the longevity and efficiency of your 1HD-series diesel engine.
OEM Toyota Quality
This Nozzle Holder Seal Set is 100% genuine OEM Toyota, manufactured in Japan to the highest standards. Each seal is engineered for precise fitment and resistance to diesel fuel, pressure, and heat, ensuring leak-free performance.
The set of six covers the full injector bank for 1HD-FTE or 1HD-FT engines, ensuring even sealing across all cylinders. These are the same seals included with Hassard Industries’ reconditioned injector kits — proven reliable in both workshop and field applications.

Recommended Usage
It is advised to replace the seals:
When fitting new or reconditioned injectors
During scheduled injector servicing
If injectors have been removed for maintenance
Whenever injector leaks or carbon buildup are detected
Replacing these seals helps maintain proper compression and prevents combustion gas from escaping past the injector seat — preserving both performance and efficiency.
