12 BU-S Parker Ferulok Tube Nut 3/4 Steel

12 BU-S Parker Ferulok Fitting

Parker Ferulok Fittings incorporate a fitting body combined with a one-piece ferrule and a nut to form a "bite type" sealing technology that eliminates the expense and time required to produce a flared SAE fluid system for medium pressure systems.

Although Ferulok fittings use a ferrule, the primary seal is formed by the ferrule biting into the tube skin, not by way of compression. This makes them particularly suited for use with medium wall and heavy wall tubing.

Ferulok fittings conform to SAE J514 and Military Spec MIL-F-18866 and are available in steel and stainless steel in a variety of sizes and configurations.
