Need an easy solution to installing the sensor for your water temperature gauge? This adapter installs in-line with your upper radiator hose and has a 3/8" NPT port. Note than most sensors are 1/8" NPT so you may need an additional 3/8 NPT (male) to 1/8" NPT (female) adapter.
Note: NA/NB radiator hose is 1.25" so for that you need our 32mm/1.25" option also listed on that site. This 38mm/1.5" version fits larger hoses for guys with non-factory 1.5" custom hose applications.
