ATS-18MM Diff Pressure Tester Adapter

June 5, 2024

Well, the tester comes with a 18mm adapter but ordered a 14mm to have for auto plugs. They sent me an 18mm. Reorder the 14mm. What the heck… 9 bucks…

Appears to be of good quality. The adapter that came with the pressure tester threads appear to be stripped or cross threaded by last user.

Polish the threads on a buffing wheel and its a lot easier to get in and out.

I purchased 2 testers and neither would fit into my 18mm spark plug holes. I had to return them and buy a different 18mm tester.
