- Engine Compression Test Kit Petrol & Diesel Glow Spark & Injector Adaptors -

---

A petrol and diesel engine compression tester kit used for checking compression pressure up to 50 bar. It is suited to fault-finding when dealing with hard starting, low power, uneven running or suspected compression loss across a range of engine types.

Used for vehicle maintenance, servicing and diagnostic work, this kit helps when assessing engine condition before deeper strip-down or repair. It is suitable for use on most cars, trucks, buses, agricultural and marine engines, making it useful in garages, workshops and for mechanics carrying out regular inspection work on mixed vehicle fleets. The included adaptors also make it relevant for both petrol spark plug applications and diesel glow plug or injector testing on many modern and older engines.

Compression pressure testing is covered up to 50 bar, with quick couplings for straight or angled versions to help when access around the engine bay is restricted. The kit includes glow plug adaptors, spark plug adaptors in M10, M12, M14 and M18, plus injector adaptors in M20, M22 and M24, along with stanadyne injector coverage and an additional pressure gauge for pressure drop testing. That spread of fittings helps cover a wide range of common testing jobs without needing separate adaptors, which is useful for regular diagnostic work across different vehicles and engine layouts.
