TU-15B Cylinder Pressure Meter for Diesel Engines
Compression testing for diesel engines requires a dedicated gauge — this TU-15B meter reads cylinder pressure directly. Purpose-built for diesel diagnostics, it isolates weak cylinders and confirms ring/valve condition without guesswork. Essential for anyone diagnosing hard starts, rough idle, or power loss on diesel platforms.
Key Features
- Diesel-rated gauge - Designed to handle high compression pressures specific to diesel engines
- Direct cylinder testing - Threads into glow plug or injector bore for accurate pressure readings
- Portable tool format - Compact enough to carry between jobs, set up in minutes
Specs
- Tool type: Compression pressure meter
- Engine application: Diesel engines only
- Configuration: Single-unit gauge with adapter
What's Included
- TU-15B pressure meter
- Adapter for diesel engine testing
Frequently Asked Questions
Do I need special adapters for different diesel engines?
The TU-15B comes with one adapter. Many diesel engines use the same glow plug or injector bore thread pattern, but you may need additional adapters depending on your specific platform — verify fitment before testing.
What compression readings should I expect on a healthy diesel?
Healthy diesels typically run 400+ PSI compression, well above gasoline engines. Refer to your vehicle's service manual for exact specifications — anything 50+ PSI below spec on one cylinder usually signals a problem.
Can I use this on a gasoline engine?
No. Diesel engines operate at much higher compression pressures. This gauge is calibrated for diesel diagnostics only — using it on a gas engine risks inaccurate readings.
