Choosing a compression tester

Use the points below as a practical starting point, then check the individual product page for the full technical information before ordering.

  • Choose a tester designed for the engine type and expected compression range.
  • Check the supplied adaptors match the spark-plug, glow-plug or injector connection used by the engine.
  • Follow the engine manufacturer test procedure so readings are taken under consistent conditions.
  • Compare cylinder results together rather than relying on a single pressure figure in isolation.

Frequently asked questions

Useful checks before selecting from this product range.

How do I choose the right Sealey Compression Testers?

Start with the intended application, then compare the dimensions, capacity, specification and compatibility shown on the individual product pages. Use the exact model or part number where the product is equipment-specific.

Are all Sealey Compression Testers products interchangeable?

No. Similar-looking products can differ in size, rating, fitment or intended use. Check the individual specification before ordering and do not assume that one model can directly replace another.

What should I do if I am unsure which product I need?

Use the product code, equipment model and application details as your reference. If you are still unsure, contact the Tanair team before ordering so the relevant information can be checked.
