Abstract
A tube coupling comprising a male member having a spherical surface at one end for extending into the flared end of a tube with a female member threadedly connected to the male member for providing a clearance space between the spherical surface of the male member and an appropriately configured and sized inside surface of the female member. A unique ferrule having a pair of concentric, spaced apart contact surfaces is mounted in the clearance space between the inside surface of the female member and the flared end of the tube when the spherical seat of the male member is within the flared end of the tube. Upon tightening of the female member on the male member, the ferrule causes the flared end of the tube to deform between its concentric, spaced apart contact surfaces and conform to the spherical seat of the male member to effect sealing.
