DPTOOL Turbo System Leakage Tester Kit 19pc — 0–6 bar Gauge, Regulator & Smoke Adapter for Turbo Hoses

DPTOOL's 19-piece Turbo System Leakage Tester Kit is a workshop-grade set that pressurizes turbo hoses, intercoolers and cooling pipes to quickly locate leaks and verify system integrity.

If your turbocharged engine suffers loss of boost or reduced performance, undetected leaks in hoses, clamps, intercoolers or radiators are often the cause. The DPTOOL Turbo System Leakage Tester Kit bundles a 0–6 bar gauge with a regulator, a shut-off valve, a smoke adapter and 16 stepped adapters to fit common hose diameters so you can pressure-test most passenger cars, light commercial vehicles and many marine or heavier applications using standard workshop compressed air.

How does this kit detect turbo system leaks?

The kit lets you seal off intake or charge hoses, pressurize the turbo plumbing with controlled workshop air, then watch the gauge and listen or use the smoke adapter to spot escaping air. If pressure drops or smoke appears at a joint, clamp or cracked pipe, you have a leak location to repair.

• Pressure range: 0–6 bar (0–87 psi) for safe, controlled testing.
• Shut-off valve and regulator for precise pressure application and locking.
• 16 stepped rubber adapters cover many common hose diameters for secure seals.
• Smoke adapter option makes small leaks visually obvious.

Which hose sizes and vehicles will these adapters fit?

The stepped adapter set spans a broad set of internal hose diameters to match intercooler and turbo charge piping found on most cars and light commercial vehicles. Adapters are sized to grip different hose thicknesses and provide a tight seal when used with the supplied stoppers.

• Covers ranges from about 31–38 mm up to 105–110 mm to match common hose diameters.
• Suitable for passenger cars, LCVs, many HGV hoses and some marine applications.
• Always confirm adapter fit for unusual or heavy-duty hoses before pressurizing.

How do you operate the DPTOOL leakage tester safely?

Start with the regulator set low, fit the correct stepped adapter and stopper, then slowly pressurize while monitoring the gauge. Use the manual red valve to cut air supply and the excess pressure release to lower pressure if needed; never exceed recommended hose pressures for the vehicle being tested.

• Preset regulator to a low pressure before connecting to compressor.
• Lock regulator by pressing down; pull up to adjust, then rotate to fine-tune.
• Use the red release valve to bleed excess pressure safely on over-pressurisation.
• Test in short increments and inspect clamps, joints and hose surfaces for leaks.

What accessories and outcomes should I expect from one test?

The kit contains adapters, a pressure gauge with regulator and shut-off, and a smoke adapter so you can both hear and see leaks. After a successful test you will know whether the turbo charge air path holds pressure or requires repair, helping you target replacements of hoses, clamps, intercoolers or pipework without guesswork.

• Immediate pass/fail reading via the gauge—pressure holding equals airtight.
• Smoke reveals small or intermittent leaks that a gauge alone might miss.
• Quick diagnosis shortens repair times and avoids unnecessary part replacements.

Who is this for? DIY mechanics, professional technicians and fleet engineers who service turbocharged engines will find the DPTOOL Turbo System Leakage Tester Kit practical and time-saving. It’s built for workshop use with standard compressed air and is ideal if you perform regular turbo or cooling-system inspections, troubleshoot boost loss, or need a reliable way to verify repairs before returning vehicles to service. Check adapter compatibility with your vehicle’s hose sizes prior to purchase to ensure the best fit.
