Review on 🧪 ABN Engine Oil Pressure and Transmission Fluid Diagnostic Tester Tool Kit – 500 PSI / 35 Bar Gauge, Hose, and Adapters" - Refining for Enhanced SEO: Engine Oil Pressure and Transmission Fluid Diagnostic Tester Kit – 500 PSI / 35 Bar Gauge, Hose, and Adapters by David Perez

I work on motorcycles so I have to route the hose of this gauge in tight places with limited access. The first time I used it I was able to tighten the threads but I couldn't tighten the hose. I figured it was my very limited access (this was my first use of a gauge) and I didn't know what size wrench was required to attach the hex to the engine-side hose. After spending 15 minutes I pulled the sensor back out and found that the hex (see picture) is 11.4mm. This can only be the result of poor quality production. it also means that a standard pipe wrench or wrench cannot be used to tighten the hose. 11mm/12mm/7/16"/1/2" are all useless. So if you're not able to use a wrench, vise or something like that, you could be in trouble. I contacted the company, explained the problem and asked for the hose to be replaced. At first they didn't want to help me but after some discussion they refunded me the money for my purchase as they couldn't send a replacement tube and they are temporarily out of stock. so it is in balance. I give him 3 stars.
