This O-ring port adapter allows you to connect a standard 16AN hose end to your Setrab oil cooler (sold separately). M22x1.5 threads are standard on Setrab oil coolers.* 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.
Note: The threads on the 16AN side of this adapter have slight flat spots. This is because the adapter is cut from raw hex stock that is slightly smaller across the flats (32.5mm) than the OD of 16AN threads (1 5/16" / 33.3mm). This does not affect performance or sealing.
