Genuine Sinotruk HOWO Fuel Injector Clamping Block - VG1200040023A

In the high-pressure environment of a Sinotruk diesel engine, stability is everything. The VG1200040023A Clamping Block is a small but vital component designed to hold the fuel injector or high-pressure lines firmly in place.

We often see aftermarket "soft-metal" clamps fail under the constant thermal expansion and vibration of a working truck. This genuine VG1200040023A is forged from high-grade carbon steel, ensuring it doesn't warp or lose its "bite" over time. Proper clamping is essential because even a fraction of a millimeter of movement can lead to injector seat erosion or high-pressure fuel leaks. Whether you are performing a top-end overhaul or just replacing an injector, using the correct OEM clamping block is the only way to ensure the engine maintains its factory-spec compression and fuel delivery efficiency.
