US PRO 5323 Petrol Engine Compression Tester Kit

The US PRO 5323 Petrol Engine Compression Tester Kit is a practical and easy to use diagnostic tool designed for checking the compression levels of petrol engines. Whether you are carrying out basic fault finding, routine maintenance, or confirming engine condition before further repairs, this kit provides a clear and reliable way to assess cylinder performance without complex setup.

Compression testing is one of the most effective ways to identify common engine issues such as worn piston rings, leaking valves, blown head gaskets, or uneven cylinder wear. This kit is built with simplicity in mind, making it suitable for DIY users, home mechanics, and general vehicle maintenance where a straightforward compression check is required.

At the heart of the kit is a large 65mm diameter gauge that is easy to read at a glance. The dual scale display shows readings in both PSI and bar, allowing compatibility with a wide range of manuals and reference values. With a measurement range of 0 to 300 PSI and 0 to 21 bar, it covers the majority of petrol engine compression requirements.

The kit includes both a rigid stem and a flexible hose, giving you the versatility to work in tighter engine bays or awkward plug positions. The flexible hose helps reduce strain on threads while ensuring a secure seal during testing. Common 14mm and 18mm spark plug adaptors are included, making the tester compatible with most petrol engines found in cars, vans, motorcycles, and small engines.

Designed for repeated use, the components are simple, durable, and easy to store, making this kit a cost effective addition to any tool collection for basic engine diagnostics.
