Description
The Duramax compression tester is a specialized diagnostic tool designed to measure the internal cylinder pressure of Duramax diesel engines, including the LLY, LBZ, and LMM models.
It operates by inserting the compression gauge adapter into the injector port of each cylinder, then cranking the engine to record the pressure generated within the combustion chamber. This allows for accurate assessment of engine health and identification of issues such as worn piston rings or valve leakage.
The tester features a threaded connection compatible with a 1/8″ NPT fitting.
