Common Fuel Rail With 2000 Bar Gauge
Best for professional workshops needing precise high-pressure measurement. This fuel rail includes a 2000 bar high-pressure gauge and high-pressure pipes to emulate real-world diesel injection conditions. It helps technicians verify fuel spray consistency and rail pressure stability during testing.
Who this is for: repair shops performing injector calibration and diagnostic work on modern common rail systems; technicians requiring accurate pressure readings during bench testing.
Caution: ensure compatibility with your existing test bench plumbing and safety gear when handling high-pressure components.
Common Rail Test Bench 5pcs (E1024128)
Best for users seeking an OEM-style fit with secure assembly. This set is built to match factory fuel line layouts, keeping components tightly connected and reducing loosening over time. The spray trajectory remains regular for consistent injector testing.
Who this is for: service centers needing repeatable bench tests with stable connections; hobbyists who value precise alignment with factory layouts.
Caution: verify compatibility with your particular rail and injector models before purchase.
Common Rail Test Bench 5pcs (E1024127)
Better for setups requiring a second, compatible test bench kit. It mirrors original specs for a factory-fit experience, with tightly joined components and a regular spray path to avoid uneven combustion caused by misalignment.
Who this is for: shops that run multiple test benches or technicians who want a backup kit with similar fit and performance.
Caution: check the exact linkage and hose sizes to ensure seamless integration with existing systems.
Diesel Common Rail Pump Injector CRIN Test Bench
Best for filtration-focused testing. This test bench accessory is designed for diesel common rail systems including CP1 and CP3, with a 5-micron filtration rating to protect components during testing and calibrations across light- to medium-duty vehicles.
Who this is for: technicians prioritizing debris protection during injector diagnosis; labs performing quality-control checks on CRIN test benches.
Caution: filtration should be paired with appropriately rated pressure components to avoid flow restriction during high-speed tests.
Bloepum AF2000-02 Filter Accessory
Best for air filtration needs on test benches. This accessory supports a filtration range and a maximum working pressure of 1.0 MPa, making it suitable for pneumatic components and clean air supply during testing.
Who this is for: users expanding filtration capability on their test setup; those who require reliable air-purge components with moderate pressure handling.
Caution: ensure the filtration rating aligns with your specific bench requirements to avoid under- or over-filtering.
Buying Guide
- Compatibility: Confirm rail and injector models supported by each kit to avoid mismatched fittings and hose sizes.
- Pressure Range: Choose a gauge and piping setup that matches the highest rail pressures you test (up to 2000 bar in some kits).
- Filtration: For injector tests, prioritize units with fine filtration to protect delicate components (5 microns is common in CRIN-focused options).
- Assembly Quality: Look for OEM-style fittings and secure joints to minimize loosening during cycles.
- Ease of Use: Consider kits with clearly labeled connections and straightforward maintenance routines.
- Safety: High-pressure testing requires proper safety gear and clean work environments to prevent accidents.
