O-Ring Boss to AN Hose Ends
These special hose ends fit our standard Stainless Steel Braided Racing Hose (Part No. 3270-Size) as well as Aeroquip Startlite Racing Hose (Part No. 3492-Size). They all have male UNF threads to fit standard SAE/JIC/AN O-Ring ports.
O-Ring boss adapters require a chamfer in the female port to provide a proper seat for the O-ring. All of these hose ends include the O-ring.
In addition to these hose ends, we also offer several different O-Ring Boss to Male AN Adapters for use with other types of hose. We also offer an extensive selection of M22x1.5 O-Ring Boss to AN Hose Ends for Setrab oil coolers.
Note: AN nomenclature can be confusing because the nominal size does not refer to the size of the threads or the OD of the hose. If the sizes are confusing you, please have a look at our Technical Document explaining The Logic Behind AN Hose and Fitting Sizes.
