O-Ring Boss Adapters and Fittings
O-Ring Bosses (ORB) use the same SAE threads as AN fittings, but ORBs do not have the 37° sealing flare that AN fittings use. O-Ring bosses seal around the face of the female port with an O-ring. Sizes are the same between AN and ORB fittings, but AN fitting nomenclature is typically "xxAN" (6AN, 10AN, 12AN) where ORB nomenclature is simply a dash number, "-xx" (-6, -10, -12).
O-Ring boss adapters require a chamfer in the female port to provide a proper seat for the O-ring. All of these adapters include the O-ring. The AN920, AN921, and AN922-sytle angled adapters also include an aluminum sealing washer. Equivalent AN numbers are given for reference where applicable. These fittings conform to JIC and SAE specifications.
In addition to these male-to-male adapters, we also offer several different O-Ring Boss to AN Hose Ends to connect directly to your standard braided AN hose. We also stock an extensive selection of M22x1.5 O-Ring Boss to Male AN Adapters for Setrab oil coolers.
Note: AN nomenclature can be confusing because the nominal size does not refer to the size of the threads. If the sizes are confusing you, please have a look at our Technical Document explaining The Logic Behind AN Hose and Fitting Sizes.
