Petrol Compression Tester Kit 598559 – Key FAQs

• What does a compression test tell you?
  It measures cylinder pressure during cranking, helping indicate the sealing condition of the engine and highlighting issues such as worn piston rings, leaking valves or gasket problems.

• What engines is this kit suitable for?
  It’s designed for petrol engines and is suitable for a wide range of vehicles and small engines that use 14mm or 18mm spark plug threads.

• What is the maximum pressure reading?
  The gauge reads up to 300psi (20bar), covering most common petrol engine compression ranges.

• What spark plug thread sizes does it fit?
  It supports 14mm and 18mm spark plug threads using the supplied fittings.

• What are the hoses and fittings made from?
  The kit uses a durable rubber hose with brass ends and steel couplings for a strong, reliable connection.

• How do I know if my compression is “good”?
  You compare readings across cylinders and check against the engine manufacturer’s specifications; consistent readings are often as important as the absolute pressure value.

• Is it suitable for professional use and DIY?
  Yes, it’s designed to be straightforward to use for capable DIYers while still offering the durability and accuracy needed for workshop diagnostics.
