Aluminum Water Temp Meter Temperature Gauge Joint Pipe Radiator Sensor Adaptor Attachment Hose Clamps （40mm/1/8''NPT）

Exactly what I needed as I didn't have a spot on block to install sensor. Good product that works good.

Worked perfectly well for my 300Zx

The 42mm water temp connector works great. I did end up having to drill and tap the 1/8 " NPT to 1/4" NPT but was easy. $10 drill and tap kit from lowes and whammo, in like flin. I used it for proper coolant tempurature on an electric fan conversion kit for diesel sprinter van.

The adapter itself is nice but the ground screw was too long: it can’t be threaded in completely not allowing a user to cinch a ground wire securely. Further, the hose clamps were to small for use with a 38mm ID radiator hose. I am going to have to replace both the ground screw and the hose clamps at additional expense. Probably should have bought a more expensive adapter and saved some money.

This adapter seems to be built well. Thought ordering is very confusing. I followed the instructions and ordered a 26mm for my kawasaki teryx. I received a 30mm adapter which was about 1/8” to big.This was frustrating as it set me back a week on my project.

Wonder fit

I haven't installed it yet, but I have thoroughly inspected it. I plan to use it on my built turbo Corvette with a Haltech ecu to mount a Bosch coolant pressure/temp sensor, so its safe to say you should grab this one if you are in the market for one. I vouch for it.
