Description of πŸ”§ Actron CP7827 Compression Tester Kit: Reliable Engine Performance Measurement Tool

Actron's Compression Tester Kit detects worn piston rings, burnt valves, and blown head gaskets. Convenient push-button side release valve allows repeated testing without the need to disconnect between tests. Gauge features a 2-1/2 inch diameter, easy-to-read face with standard and metric scales: 0-300 PSI and 0-2100 kPa. 17 inch, high-pressure, flexible, oil and grease resistant hose features a quick release connection at the gauge for faster, easier use. 14mm and 18mm ends fit most thread sizes while included 14mm long reach adapter is perfect for many late model vehicles wth deeply recessed spark plugs.

Works great but TIGHTEN ADAPTER

Product works as advertised. BUT; Take another second to tighten the adapter onto the hose. Otherwise, after screwing the adapter into the head, the hose will unscrew from the adapter, leaving the adapter screwed into the head. With most engines, you don't have room for an outlet around the adapter. I had to apply CA to the threads on the hose, screw it back into the adapter, let it dry, then unscrew the adapter and head. It was an easily avoidable headache. Simply place a wrench on the adapter

Pros
  • Gauge is 2-1/2" diameter easy to read surface with standard and metric scales: 0-300psi and 0-2100kPa
Cons
  • Fits

Did I get a fake?

The pressure gauge I received will never work. This raises doubts whether I received a fake or all the positive reviews are lies. The pressure gauge uses a non-standard air hose coupling with an O-ring to ensure tightness. Because the check valve is on the other end of the hose (closest to the engine), this air coupling needs to be perfectly sealed to get accurate readings and to hold readings and not instantly reset to zero. Well the o-ring has absolutely nothing to hold it in place. So as…

Pros
  • Actron Compression Test Kit detects worn piston rings, burned valves and head gaskets.
Cons
  • Compatibility

Robust pressure gauge suitable for diagnostic, test and measuring equipment

This compression tester is easy to use and quickly shows over the condition of your bottles or the quality of your recovery. I recently converted a Honda Civic and during a compression test the readings were initially fine (over 100psi) per cylinder (dry compression results). However after a few cranks all readings have dropped to zero, at first I thought the sensor was broken but it was absolutely fine, my timing belt slipped causing the cam timing to fail and the valves were open at the TDC…

Pros
  • Flexible, oil and grease resistant 17 inch high-pressure hose with quick coupling on the pressure gauge for quicker and easier use
Cons
  • Some difficulties
