ABN Engine Oil & Transmission Pressure Tester Kit — 500 PSI / 35 Bar Gauge, 60in Hose & Brass Adapters

ABN's Engine Oil Pressure and Transmission Fluid Diagnostic Tester Tool Kit is a complete, heavy-duty set for measuring oil and transmission fluid pressure up to 500 PSI (35 Bar) on most cars and small trucks.

Know your vehicle's fluid pressures quickly and clearly: this kit provides a dual-scale gauge, a 60-inch reinforced rubber hose, solid brass fittings and adapters, and a convenient blow-molded case so you can diagnose oil or transmission pressure issues at the vehicle without guesswork. The gauge reads both PSI and Bar and installs in place of the oil pressure sending unit or switch for a direct, mechanical measurement.

How do I use this tester to check engine oil pressure?

Remove the engine's oil pressure sending unit or switch and thread the tester into the same port. Start the engine and observe the dual-scale gauge to get an immediate reading in PSI and Bar.

• Thread-in replacement for oil sending unit or pressure switch
• 60-inch hose lets you position the gauge off-engine for safer viewing
• Dual-scale gauge displays up to 500 PSI / 35 Bar for clear readings
• Brass fittings resist corrosion and maintain a tight seal

Can this kit test transmission fluid pressure too?

Yes — with the correct adapter and hose routing, the tester can connect to the transmission pressure port to capture fluid pressure readings. Use the included adapters or the brass extension tube to reach common transmission fittings.

• Includes multiple adapters to fit a variety of domestic and imported vehicles
• Brass extension tube helps access hard-to-reach ports
• Durable hose rated to 500 PSI avoids expansion under pressure
• Mechanical gauge gives direct, repeatable pressure values

What are the kit’s materials and durability features?

The kit is constructed with longevity in mind: brass fittings and extension tube plus a rubber hose rated to 500 PSI provide reliable performance in workshop environments. The gauge has a protective black coating and the set stores in a sturdy blow-molded case to reduce wear during transport and storage.

• Solid brass fittings and adapters for corrosion resistance
• 60-inch reinforced rubber hose rated to 35 Bar (500 PSI)
• Black-coated gauge housing for added protection
• Heavy-duty carrying case (13" x 10" x 2.3") for organized storage

What’s included and how does it simplify diagnostics?

The kit arrives ready for most common jobs: several brass fittings, a selection of adapters, an extension tube, the pressure gauge, a long hose, and a compact case. That combination lets a DIYer or technician quickly adapt the tool to different ports without scavenging parts.

• One dual-scale 500 PSI / 35 Bar pressure gauge
• Sixty-inch rubber hose for safe distance measurements
• Six brass fittings, four adapters, and one brass extension tube
• Blow-molded carrying case for transport and organization

Who is this for: The ABN Engine Oil Pressure and Transmission Fluid Diagnostic Tester Tool Kit is designed for home mechanics, professional technicians, and fleet maintenance staff who need a reliable mechanical gauge setup to diagnose oil or transmission pressure issues. It's suitable for most American and imported cars and small pickup trucks, and for anyone who prefers direct, instrumented pressure readings over electronic diagnostics.
