Full details
This guide is for mechanics and automotive enthusiasts who need to diagnose catalytic converter and exhaust system issues. The Sealey Catalytic Converter Back Pressure Test Kit (VSE953) helps you quickly assess the condition of your catalytic converter by measuring back pressure. A key benefit is the ability to diagnose issues without removing components, though it's important to note that this kit measures relative back pressure, not absolute values, so it is useful when comparing to a known good value.

FAQs
What does the gauge measure?
The gauge measures back pressure in the exhaust system and vacuum in other systems like low-pressure fuel systems and engine vacuum.
How do I connect the kit?
Connect the appropriate adaptor into the oxygen sensor port or other suitable location in the exhaust system. Then attach the gauge to the adaptor.
What does high back pressure indicate?
High back pressure typically indicates a restriction in the exhaust system, such as a blocked catalytic converter or silencer.
Can I use this kit on all vehicles?
The kit is compatible with most vehicles. However, it's best to consult the vehicle's service manual.
What should I do if the gauge reads zero?
Check all connections for leaks or obstructions. Ensure the engine is running and that the system is sealed.
How do I interpret the color-coded scale?
The color-coded scale on the gauge provides a quick reference for diagnosing potential issues within the exhaust system. Consult the manual for specific interpretations of each color range.
Where can I find replacement parts?
Contact your local Sealey distributor or check the Sealey website for replacement parts.
