Rated 1 out of 5 by from They can't figure out 1/8NPT27 vs 1/8NPT28 I purchased this kit and the sensor barely went in 1 turn and bound up on the fittings it comes with; I tried different fittings as well to no avail. I then took out my tap and die set which has both 1/8NPT27 and 1/8NPT28 taps and dies. The sensor is cut to 1/8NPT27 and most fittings including the ones that come in the kit are commonly in 1/8NPT28. Once realizing this I called AutoMeter and was told they've been doing this for 40years and never had anyone complain about this and that even though they are different threads it works fine. My concern is that you are essentially cross threading a soft material (brass) and potentially making the sensor useless to reuse or relocate since the threads are now damaged from being forced into improper threads. To AutoMeter if you read this I encourage you to change you sensor thread cutting process to match the more commonly used 1/8NPT28 size and get better employees in your customer support/service department that will try to help instead of tell them off.

Greetings, is this temperature gauge compatible with the 2259 short sweep sensor? From what I’ve read the included sensor is too long for my transmission (2004 f150). This shallow sensor was suggested to me.

Asked by: JJ24
Thank you for your question. Unfortunately, 6949 has to be used with sensor 2252. If it does not fit your application you would have to look at using an alternate gauge or alternate application for a sensor.
