Product Description

The Exhaust Back Pressure Tester Gauge Kit allows you to quickly and accurately diagnose blockages in your vehicle’s exhaust system. By measuring back pressure at idle and 2500 RPM, this kit helps detect clogged catalytic converters, restricted mufflers, and other exhaust issues that can cause poor acceleration, engine overheating, or sluggish performance. Featuring a 2.5-inch dual-scale PSI/BAR gauge with color-coded indicators, a heat-resistant 3.28 ft silicone hose, and M12/M18 adapters, this tester is ideal for professional mechanics, car dealers, and DIY enthusiasts seeking reliable diagnostics.

Product Feature

• 👍Professional Diagnosis of Exhaust Blockage Fault:Exhaust back pressure gauge tester helps accurately diagnose exhaust system restrictions, quickly identifying clogged catalytic converters or mufflers to prevent sluggish engine performance, reduced acceleration, and overheating.
• 👍Simple and Practical Exhaust Back Pressure Gauge Kit: Test exhaust pressure at idle speed and 2500 RPM; idle pressure should not exceed 1.25 PSI (0.09 bar), and readings in the red zone at 3 PSI (0.21 bar) indicate exhaust blockage.
• 👍HD Dual Scale Pressure Gauge & Shockproof Rubber Cover: Features a 2.5" high-visibility dual-scale gauge (PSI/Bar) with color-coded indicators for quick diagnosis, protected by an anti-vibration rubber cover to reduce impact damage.
• 👍3.28 FT Abrasion & Heat-Resistant Hose with M12 & M18 Adapters: High-quality silicone hose offers excellent heat and wear resistance, with sufficient length for testing from the driver’s seat, and includes M12 and M18 thread adapters for wide compatibility.
• 👍Warm Tips: Each pressure gauge is factory calibrated; if the needle is not at zero due to shipping impact, it can be manually adjusted without affecting measurement accuracy.
