Rothewald 3-in-1 Compression Tester 10/12/14mm

If the performance of a petrol (gasoline) engine drops for no apparent reason, then taking a compression measurement on the individual cylinders should help you to track down the problem. The Rothewald 3-in-1 Compression Tester is ideal for this job. It allows you to do both "dry" and "wet" (with the addition of oil) pressure tests on the cylinders.

Features:

• Suitable for 10, 12 and 14 mm spark plug threads
• Suitable for all petrol (gasoline) engines
• Display in bar and psi
• Measures pressures up to 20 bar (300 psi)
• Includes 3 rubber hoses with brass adapters for 10, 12 and 14 mm spark plug threads plus valve and O-ring replacement set

Good to know:
The target is for the readings to comply with the manufacturer's specifications. Normally the individual pressure readings should not vary by more than 10% between cylinders or from the engine manufacturer's specifications.
