The adapter fits standard oxygen sensor ports in both 12mm and 18mm sizes, making it compatible with the vast majority of modern and older vehicles. Always verify your vehicle's oxygen sensor thread size before use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does a high back pressure reading indicate when using this exhaust tester?\u003c\/h4\u003e\n\u003cp\u003eA: Higher-than-normal readings typically indicate a restriction within the exhaust system — such as a clogged catalytic converter or a collapsed muffler. For reference, pressure should remain below 1.25 PSI at idle and below 3 PSI at 2,500 RPM. Readings above these thresholds suggest the exhaust system should be inspected and serviced.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this pressure gauge kit suitable for DIY home mechanics?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The kit is designed for both professional mechanics and home garage enthusiasts. It comes in a convenient blow-molded carry case with all adapters included, and the large dual-scale dial (0–300 PSI \/ 0–20 Bar) makes readings easy to interpret without specialized training.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this gauge measure both compression and vacuum pressure?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
