DPTOOL Turbo System Leak Tester Kit 19-piece — 0–6 bar Gauge, Regulator & 16 Adapters for Turbo, Intercooler Hoses

The DPTOOL Turbo System Leakage Tester Kit is a 19-piece air-pressure test set designed to locate and confirm leaks in turbo systems, intercoolers and cooling hoses quickly and accurately.

This professional-grade kit bundles a 0–6 bar (0–87 psi) pressure gauge with an integrated regulator and shut-off valve, a smoke adapter, and 16 stepped adapters sized to fit common turbo and cooling pipes. It works with standard workshop compressed air to pressurize hoses and intercoolers so you can spot loss of boost pressure, audible leaks, or visible pressure drops, helping you diagnose turbo-related performance issues without removing the whole system.

How do I use the kit to find a turbo boost leak?

Set the regulator to a low test pressure, plug the intake or exhaust ports with the supplied stoppers and attach the correct stepped adapter for the hose diameter. Pressurize the system slowly, watch the gauge for drops, and listen or apply soapy water to suspect joints to see bubbling.

• Select an adapter that matches the hose ID for a snug seal.
• Attach the gauge assembly and slowly increase pressure using the regulator.
• Check for pressure hold on the gauge or use soap/smoke for visual leak detection.
• Release pressure safely via the red excess valve after testing.

What parts are included and what sizes do the adapters cover?

The kit contains 19 pieces: a pressure gauge with shut-off and regulator, a smoke adapter, plus 16 stepped rubber adapters that span a wide range of pipe diameters. The adapters cover increment ranges commonly found on cars, light commercial vehicles and many marine applications.

• Gauge range: 0–6 bar (0–87 psi) for accurate pressure readings.
• 16 stepped adapters cover roughly 31–110 mm pipe diameters in stepped ranges.
• Smoke adapter lets you use smoke machines where pinpointing small leaks visually helps.
• Red manual valve and regulator allow controlled pressurization and safe release.

Which vehicles and systems can this tester be used on?

Designed primarily for turbocharged petrol and diesel engines, the DPTOOL set fits most passenger cars, light commercial vehicles (LCV), some heavy vehicles, and marine engine hoses. It also works well for intercoolers, radiators and other pipe assemblies where pressure testing reveals leaks.

• Passenger cars and light commercial vehicles: broadly compatible.
• Some heavy commercial and marine systems where adapter sizes match.
• Suitable for intercoolers, turbo pipes, radiator hoses and cooler lines.
• Always confirm adapter fit for your specific hose diameters before use.

How does the gauge and regulator improve testing accuracy and safety?

The built-in 0–6 bar gauge gives a clear visual of system pressure while the regulator controls the applied pressure to avoid over-pressurisation. A shut-off valve locks the pressure during inspection and a manual excess-release valve provides a safe way to bleed pressure.

• Regulator locks when pressed down; pull up to adjust and rotate to set pressure.
• Shut-off valve isolates the tester to hold pressure for leak confirmation.
• Excess pressure release prevents damage from accidental over-pressurising.
• Clear numeric gauge lets you verify if boost loss is occurring under static conditions.

Who is this for: The DPTOOL Turbo System Leakage Tester Kit suits mechanics, DIY enthusiasts and fleet technicians who need a reliable, portable method to diagnose turbo and cooling-system leaks. If you service turbocharged engines, perform intercooler repairs, or routinely troubleshoot boost-related problems, this kit provides the adapters, gauge and control you need to find leaks faster and with less disassembly. Always use with a regulated workshop air supply and verify adapter compatibility with your vehicle’s hose diameters before testing.
