KATSU Tools Diesel Injector Nozzle Pop Tester 600 Bar 8700 PSI Gauge 449949

KATSU Tools Diesel Injector Nozzle Pressure Tester 0-600 Bar / 0-8700 PSI | Fuel Injector Pop Tester Kit with Dual Scale Gauge & Transparent Reservoir

Overview Diagnose, calibrate, and service your diesel fuel injection system with professional accuracy using the KATSU Tools Diesel Injector Nozzle Pressure Tester (SKU: 449949). This heavy-duty "pop tester" kit is designed to comprehensively measure injector opening pressure, analyze fuel spray pattern atomization, and efficiently detect critical valve leaks or chatter faults.

Equipped with a precision dual-scale pressure gauge reading up to 600 Bar (8700 PSI), a durable manual hand pump, and a filtered transparent fuel reservoir, it provides mechanics and DIY hobbyists with a reliable, shop-grade diagnostic solution. It is highly suitable for servicing a wide range of diesel engines, including passenger cars, vans, agricultural tractors, marine vessels, and light commercial vehicles.

Key Features & Benefits

  • High-Pressure Diagnostic Power: Accurately builds and holds pressure up to 600 Bar / 8700 PSI, allowing you to easily test structural leakage, needle seating sealing, and precise nozzle opening thresholds.

  • Easy-to-Read Dual Scale Gauge: Features a high-contrast dial showing both BAR and PSI measurements simultaneously, ensuring precise, error-free calibration according to factory workshop manuals.

  • Controlled Hand Pump Operation: Engineered with a heavy-duty manual lever and a smooth pump piston assembly that gives you total manual control over pressure increments and cycle speeds.

  • Transparent Reservoir with Built-in Filter: The transparent oil/fuel tank lets you instantly monitor fluid levels and clarity, while the integrated internal filter traps microscopic debris to ensure clean testing and protect delicate injector nozzles.

  • Multi-Fit M12 & M14 Pipes Included: Supplied with high-pressure connection pipes in standard M12 and M14 thread sizes, making the kit instantly compatible with the majority of automotive and agricultural diesel injectors on the market.

⚠️ Important Operational Safety & Care Tips

  • Wear Personal Protective Equipment (PPE): Diesel fuel or calibration fluid under high pressure can easily pierce human skin, which is extremely hazardous. Always wear heavy-duty safety gloves, protective clothing, and safety goggles when operating this pop tester. Never put your hands or fingers in front of the spraying nozzle tip!

  • Use Correct Testing Fluid: For optimal tool longevity, we highly recommend using a dedicated, commercial-grade ISO 4113 calibration fluid or clean, fresh, premium diesel oil. Never use old, contaminated fuel or thick oils that can clog the internal valves.

  • Bleed Air Before Testing: When connecting a new injector, pump the lever gently a few times with the fitting slightly loose to purge any trapped air pockets out of the line, ensuring a solid fluid column for precise pressure reading.
