THE BETABITE PRINCIPLENutCoupling BodyTHE BETABITE PRINCIPLETubeFerrule Secondary Bite Primary BiteAs the coupling nut is tightened, the ferrule moves along the tube. When the ferrule outside diameter contacts the innertaper of the coupling body, the front cutting edge (1) of the ferrule makes the primary “bite” cleanly into the outer surfaceof the tube. At the point where the secondary “bite” (2) comes into contact with the surface of the tube, a sharp increasein torque will occur. This signals to the operative that a perfect, pressure-tight joint has been achieved and no furthertightening is necessary. At the same time, the ferrule is clamped firmly by the nut on the tube (3) providing a perfect antivibrationlock.ADVANTAGES OF THE BETABITE PRINCIPLEBBTHREE POINT CONTACT WITH OUTSIDE DIAMETER OF TUBE.BBSUPERIOR SEALING QUALITIES.BBTHE OPERATIVE WILL “FEEL” WHEN A PERFECT JOINT HAS BEEN MADE.BBREMOVES POSSIBILITY OF OVERTIGHTENING.BBAVOIDS NARROWING OR “NECKING” OF THIN-WALL TUBES.BBJOINT MAY BE BROKEN AND RE-MADE REPEATEDLY.3
