OVERVIEW

These anodized billet aluminum adapter fittings can be used in any application using a 9/16"-18 O-ring port. This is the same thread pitch used in 6AN ORB (O-Ring Boss) fittings. They all feature FKM O-rings for all oil and fuel types. O-rings should be lubricated with engine oil, o-ring lube, or petroleum jelly before installation.
