Abstract
1,202,186. Tube couplings. PARKERHANNIFIN CORP. 30 Jan., 1969, No. 5230/69. Heading F2G. A tube coupling comprises a ferrule 4 which is arranged to be radially contracted at one end into gripping and sealing engagement around a tube T by being urged against a flared mouth 5 of a body 2 by a nut 3 which is in threaded engagement with the body 2. The flared mouth 5 has a 15 to 25 degrees taper and the ferrule 4 is provided with an external tapered portion of taper less than the flared mouth 5 and the maximum thickness of the ferrule is substantially twice the minimum thickness of the one end of the ferrule. The tapered portion of the ferrule 4 adjacent the one end merges into a taper of substantially the same angle as the flared mouth for initial engagement with the flared mouth 5. The ferrule is provided at its other end with a portion 12 which is guided in a counterbore 76 of the nut 3. In the construction shown the other end of the ferrule is provided with a beveled face 13 adjoining an annular end face 15, the line between the two faces being initially in engagement with a shoulder 6 of the nut. When the nut 3 is tightened on the body both ends of the ferrule are urged into engagement with the tube, the one end of the ferrule biting into the tube (Fig. 3, not shown). The annular end face is approximately 0À005 inch to 0À010 inch in radial width, and the radial inner corner of the annular end face is beveled 0À005 inch maximum.
