DKwoeshg Engine & Transmission Oil Pressure Test Set — 2 Gauges, 14-Adapter Kit with 72in Hose, 0–400/0–100 psi

The DKwoeshg Master Engine and Transmission Oil Pressure Test Set is a professional-grade kit that lets you quickly measure high- and low-side oil pressure on most cars and light trucks with accurate gauges and 14 adapters.

This comprehensive testing kit combines two calibrated pressure gauges, a long service hose, and a broad range of brass and aluminum adapters so you can diagnose oil pressure issues on engines and transmissions without guesswork. Built for shop durability, the set stores neatly in a molded case and adapts to metric, NPT, and BSPT fittings. Whether you’re troubleshooting low oil pressure, verifying pump output, or confirming transmission line integrity, the kit gives clearly readable data to guide repairs.

How do the gauges cover both engine and transmission pressure?

The set includes two dedicated gauges with different ranges so you can test low engine pressure and high transmission pressures with the appropriate scale for accurate readings. Both gauges have hanging hooks for hands-free use and are easy to read at a glance.

• Gauge ranges: 0–100 psi (0–700 kPa) and 0–400 psi (0–2800 kPa).
• Clear dials and hanging hooks for convenient reading during tests.
• Designed for high- and low-pressure diagnostics without swapping instruments.
• Calibrated for automotive oil and transmission fluid pressures.

Which adapters come with the kit and what vehicles do they fit?

The kit supplies 14 thread adapters covering common NPT, metric, and BSPT sizes in straight and elbow configurations so you can connect to a wide range of engine blocks, oil galleries, and transmission test ports. The variety minimizes the need for additional fittings in most passenger cars and light trucks.

• Includes 14 brass and aluminum thread adapters for broad compatibility.
• Adapters in straight and elbow styles to reach confined ports.
• Suitable for many domestic, Asian, and European passenger vehicles and light trucks.
• Quick-change fittings let you swap adapters onsite without tools.

How durable and portable is the kit for shop use?

Components are built from robust brass and aluminum with a heavy-duty hose and protective case to handle frequent use. The molded carrying case keeps everything organized and reduces wear during transport between jobs or in a mobile service rig.

• Sturdy molded storage case for safe transport and organized storage.
• 72-inch hose gives reach into engine bays and chassis locations.
• Metal adapters resist corrosion and repeated connection cycles.
• Gauges designed for professional shop environments and repeated handling.

How do I use the set safely and get reliable readings?

Shut off the engine or follow manufacturer test procedures before connecting to pressurized circuits. Attach the appropriate adapter to the test port, secure the hose, then run the engine or apply pressure per the vehicle service manual while observing the correct gauge range.

• Follow vehicle manufacturer test steps and safety precautions.
• Select the gauge and adapter suited to the port and expected pressure.
• Use the hanging hook for a stable, hands-free reading during tests.
• Depressurize lines and clean ports after testing to avoid contamination.

Who this is for: The DKwoeshg Master Oil Pressure Test Set is aimed at professional mechanics, automotive technicians, and serious DIYers who need dependable engine and transmission pressure diagnostics. It’s especially useful for shops that service multiple vehicle makes, mobile mechanics who require a portable, organized kit, and owners troubleshooting pressure-related engine or transmission issues who want clear, repeatable measurements before ordering parts.
