18-Piece Diesel Compression Gauge Set

Diesel compression tester kit for accurate cylinder pressure readings on light and heavy diesel engines.

This 18-piece diesel compression gauge set helps technicians and serious DIYers diagnose engine health by measuring cylinder pressure on common diesel platforms. The dual-scale gauge reads 0 to 1000 PSI and 0 to 70 BAR, with adapters covering popular glow plug and injector ports.

Why this diesel compression tester works

• Wide engine coverage: 18 pieces include the most common adapters for diesel cars, light trucks, and small commercial engines.
• Clear dual-scale gauge: 0 to 1000 PSI and 0 to 70 BAR markings make comparing cylinders quick.
• Flexible hose: The extended hose reaches deep glow plug ports without removing extra components.
• Organized case: A molded carry case keeps every adapter in its slot for fast setup.
• Repeatable readings: Quick-release coupling lets you cycle through cylinders without losing pressure between tests.

Frequently asked questions

What does a diesel compression tester do?
It measures the pressure inside each cylinder during the compression stroke, helping you identify worn rings, leaking valves, or head gasket issues before they become bigger repairs.

Does this kit work on multiple diesel engines?
Yes. The 18-piece set ships with multiple glow plug and injector adapters so it fits a wide range of common diesel cars, light trucks, and small commercial engines.

How accurate is the 0-1000 PSI gauge?
The dual-scale gauge reads up to 1000 PSI / 70 BAR with clearly marked increments, giving you the resolution needed to spot a weak cylinder against the rest.

Is the case durable for daily shop use?
The blow-molded carrying case keeps every adapter in its own slot, so the kit stays organized in a service bay or under a workbench between jobs.
