VCT Engine & Transmission Oil Pressure Test Kit — 0–400/0–100 psi Gauges, 72" Hose, 14 Adapters

The VCT Engine & Transmission Oil Pressure Test Kit is a professional-grade diagnostic set with two precision gauges (0–100 psi and 0–400 psi), a 72" oil-resistant hose, and 14 thread adapters to test a wide range of engines and transmissions.

Whether you’re troubleshooting low oil pressure, verifying pump performance, or diagnosing transmission hydraulic issues, this kit supplies the fittings and reach to connect securely to most service ports. Built with a flexible, high-temperature hose and durable gauge housings, it’s designed for repeatable readings in garages and mobile service vans. The kit combines high and low-range gauges so you can quickly switch between applications without changing tools.

How does the kit measure both low and high system pressures?

The set includes two calibrated analog gauges covering 0–100 psi for low-pressure checks and 0–400 psi for higher-pressure circuits. Each gauge is clearly marked in psi and kPa, letting you match specifications from service manuals.

• Low-range gauge: 0–100 psi (0–700 kPa) for oil galleries and light hydraulic checks.
• High-range gauge: 0–400 psi (0–2800 kPa) for pumps and transmission lines.
• Hanging hooks for hands-free monitoring during warm-up or load testing.
• Robust housings reduce vibration effects for steadier readings.

What vehicle connections and adapters are included for compatibility?

The kit ships with 14 thread adapters in common NPT, metric, and BSP sizes and with straight, elbow, and 90-degree fittings to reach awkward test ports. This variety increases the chance of a direct, leak-free connection without jury-rigging adapters.

• NPT, metric, and BSP threads for domestic and imported vehicles.
• Straight, elbow, and 90° adapters to access tight locations.
• Quick-connect fittings for rapid gauge hookup and removal.
• Adapters stored in a compact case to prevent loss and keep parts organized.

How does the long hose and hose construction improve diagnostics?

The 72-inch hose gives technicians ample reach to connect gauges to deep or rear-mounted ports without moving the engine or transmission assembly. The hose is engineered to resist oil, heat, and kinking so readings stay consistent and the line lasts through repeated shop use.

• 72" length for easy access to remote test points.
• Oil-resistant, high-temp rubber prevents swelling and cracking.
• Flexible construction reduces stress at fittings and keeps interfaces sealed.
• Metal-sleeved ends improve durability at connection points.

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

Prioritize secure connections, engine-off attachment when possible, and follow manufacturer pressure procedures. Use the low-range gauge for initial checks and switch to high-range for pump verification; always relieve system pressure before disconnecting fittings.

• Attach an appropriate adapter for a leak-free connection before starting the engine.
• Warm engine to operating temperature for accurate pressure comparisons.
• Use the hanging hook to keep gauges visible and stable during tests.
• Bleed air from the hose to avoid false low readings caused by trapped bubbles.

Who this kit is for: Professional mechanics, fleet technicians, and serious DIYers who need a reliable, adaptable oil-pressure and transmission-pressure diagnostic tool. If you service multiple vehicle makes or perform regular pump and pressure checks, the VCT kit supplies the measurement range, reach, and adapter selection to speed diagnosis and reduce rework. It’s especially useful where access is limited or when both low and high-pressure readings are required in the same job.
