LEIMO KPARTS Oil Pressure Tester Kit 0–140 PSI — 3" Dual-Scale Gauge, 10 Adapters, 4 ft Reinforced Hose

LEIMO KPARTS Oil Pressure Tester Kit is a complete 0–140 PSI diagnostic gauge set that lets you measure engine oil pressure quickly and accurately to verify sensor and system performance.

Whether you are a DIY mechanic or a professional technician, this compact kit provides a large 3" dual-scale gauge, a reinforced 4 ft hose rated to 300 PSI, and ten common adapters to fit most cars, trucks and ATVs. The kit helps determine if an instrument-cluster oil light, oil pressure sensor or engine lubrication problem requires repair, by comparing measured pressure against the manufacturer's recommended range.

How do I use the tester to read engine oil pressure?

Using the kit is straightforward: remove the vehicle's oil pressure sensor, attach the correct adapter and screw the tester into the sensor port. Start the engine and observe the gauge reading; compare the value to the vehicle maker’s specified idle and running pressure ranges to interpret results.

• Select the matching adapter from the included set (M10–M18, various NPT/UNF sizes).
• Attach the 4 ft rubber hose with either the straight or 90° quick coupler as needed.
• Start engine, note static (idle) and revved RPM pressure readings.
• Shut engine off, remove tester, and reinstall original sensor or repair parts.

What vehicle types and engines will this kit fit?

The adapter assortment covers a broad range of import and domestic gasoline engines used in cars, light trucks, SUVs and ATVs. The marked adapters make it easy to find the right fit, reducing cross-thread risk and saving time during diagnosis.

• Ten stamped adapters including M10, M12, M14, M16, M18 and common NPT/UNF sizes.
• Straight and 90° quick couplers for tight or awkward sensor locations.
• Dual-scale gauge supports readings in PSI and Bar for global vehicles.

How durable and safe is the gauge kit for workshop use?

Built from steel, brass, aluminum and reinforced rubber, the tester is designed for repeated garage use. The gauge has a protective cover and the red molded carrying case secures tools during transport and storage, helping prevent damage from drops or impacts.

• Hose rated to 300 PSI, made of rubber with nylon reinforcement for temperature and torsion resistance.
• Steel adapters and brass couplers for rust resistance and reliable sealing.
• Molded hard case measuring 13" x 10" x 2" for organized storage and protection.

Who this kit is for: The LEIMO KPARTS Oil Pressure Tester Kit is suited to home mechanics, mobile technicians and fleet maintenance teams who need a dependable, portable way to confirm oil pressure, troubleshoot warning lights and rule out false sensor faults. It’s also useful for pre‑purchase inspections or routine engine health checks when you want a clear, numerical oil pressure reading rather than relying on dashboard indicators.
