Brand: Setrab Oil Coolers
This O-ring port adapter screws directly into your Setrab oil cooler (sold separately) to connect a 1/2" ID rubber hose without a separate hose end. M22x1.5 threads are standard on Setrab oil coolers.* The M22 end swivels so you can aim the barb in whatever direction you need. Includes O-ring. Sold individually.
* Note that the 6-series coolers (13" long / 11 1/8" without mounting tabs) are also made with -16 O-ring ports; be sure to check before ordering if you have a 6-series cooler.
