OTC 7215 Exhaust Back Pressure Gauge

I ordered this tool via a confident reference and expected all in order…until I read reviews below describing mismatched parts, incomplete set with no adapters, defective metal… all of it. It scared the heck out of me while it was shipping. I even emailed to OTC about how I could order adapters if they were missing. In their words, “all 4 of those parts are obsolete without replacement“.I received everything. 2019 and 2021 must have been a fluke.I am not a mechanic and I wonder about my installation of the tool, but I got a below 0 reading on my catalytic converter back pressure and I am unsure what that indicates, whether installation was improper, the equipment was damaged or defective, or if the cat has a leak.

After using it twice, it paid for itself. Takes the guess out of bad Catalytic Converters.

This tool is simple to use, if only getting to the hole to install it in was that easy.

The gauge is big and easy to read. The steel braided hose is good and just long enough. The gauge is 1/4" pipe and the hose is 1/8" pipe. You'll have to buy adapters to connect them together. Otherwise it works fine. It only fits one size sensor so you might need an adapter there also. I was lucky.

I use this tool every time a car comes in with a suspected Catalytic Convertor failure and when used with my Snap-On Scan tool, I've saved many customers thousands of dollars by correctly diagnosing their vehicles the first time (and only half of the vehicles with Cat Codes P0420/P0430 actually needed a new Cat).

works great , im happy with this tool, only its not easily adaptable , could use easier attachments for the not so easy to get to O2 sensor location considering exhaust gets very hot in a short time. not a great value but it a good tool. I would still recommend it for it s good quality and usefulness.

A great way to see if there are any pressure in the motor.

A gift for my son who is a professional mechanic. He says it works well.

Bon produit

worked well and had the correct adapter for my application, the braided hose stays cool enough to handle and protects from damage. a hard case would be nice, but that's about it.
