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

LEIMO KPARTS Oil Pressure Tester Kit is a complete 0–140 PSI gauge set with ten adapters and a 4 ft reinforced hose for fast, reliable engine oil pressure checks on cars, trucks and ATVs.

Accurate oil pressure readings help you determine whether the vehicle’s oil delivery system, pressure sender or dashboard gauge is functioning within the manufacturer’s recommended range. This kit supplies a large 3" dual-scale gauge (PSI and Bar), a heavy-duty rubber hose rated to 300 PSI, brass quick couplers and a full complement of adapters to fit most import and domestic engines. Packaged in a molded red case, the kit is built for shop use and garage storage alike.

How do I use the kit to test engine oil pressure?

Testing is straightforward: remove the stock oil pressure sensor, attach the matching adapter and secure the quick coupler to the test port. Start the engine and read the gauge; compare the measured value to the vehicle maker’s recommended range to determine if pressure is normal.

• Select the correct adapter (marked) for your engine’s fitting.
• Screw the adapter into the sender port, attach the hose quick coupler.
• Warm the engine to operating temperature and idle to get a steady reading.
• Record pressure in PSI or Bar and compare to manufacturer specs.

What components are included and what materials are used?

The kit contains a 3" gauge with shockproof cover, a 4 ft reinforced rubber hose, a straight and 90° quick coupler, and ten adapters covering common thread sizes and standards. Precision parts are made from steel, brass, aluminum and copper for corrosion resistance and durability.

• 3" dual-scale gauge (0–140 PSI / 0–10 Bar).
• 4 ft reinforced hose rated to 300 PSI working pressure.
• Brass quick couplers and steel/aluminum adapters: R1/8, 1/8"-27 NPT, 1/4"-18 NPT, 3/8"-20 UNF, 1/2"-20 UNF, M10–M18.
• Red molded storage case for protection and transport.

How durable and safe is this pressure tester kit?

Parts are engineered for workshop conditions: the hose resists heat, torsion and pressure fatigue while metal adapters and couplers are hard, rust-resistant and form tight seals. The gauge includes a protective cover to reduce impact damage during routine garage use.

• Reinforced rubber hose for long service life under stress.
• Hard metal adapters with good sealing and rust resistance.
• Shockproof gauge cover and molded case for drop protection.
• Wide gauge range for precise readings across vehicles.

Can this gauge handle different vehicle types and standards?

Yes — the dual-scale gauge reads in both PSI and Bar for international compatibility, and the adapter assortment covers many common metric and imperial thread sizes used on cars, trucks and ATVs. The kit is intended for diagnostics, not continuous monitoring.

• 0–140 PSI and 0–10 Bar dual scale display.
• Adapters labeled for easy selection across import/domestic engines.
• Works with standard sender ports using the supplied quick couplers.
• Useful for spot-checks during maintenance and troubleshooting.

Who is this for: The LEIMO KPARTS Oil Pressure Tester Kit is aimed at mechanics, DIY enthusiasts and fleet technicians who need a reliable, portable tool for diagnosing oil pressure problems. It’s helpful for anyone troubleshooting oil pump performance, sender or gauge accuracy, and routine engine inspections on cars, light trucks and ATVs who wants clear numeric readings instead of relying solely on dashboard warnings.
