amount of torque necessary to deform the gripping means 42 into the surface of the tubing the external arc of each individual wedge member 48 has a shorter arc length than the internal arc length of the wedge member this feature facilitates axial compression of the collet to grasp the tubing without creating undesirable rotation of the collet by the rotating nut the collet camming surface 46 is of greater angle of taper than the nut camming surface 26 in the preferred embodiment the collet camming surface 46 is oriented at approximately 18 u00b0 20 u00b0 relative to the collet bore 40 while the nut camming surface 26 is oriented at approximately 18 u00b0 20 u00b0 relative to the nut bore 22 with the chosen collet camming surface 46 having a greater angle of taper than the nut camming surface fig2 illustrates the connector assembly 10 in a partially assembled position slideably engaging a piece of tubing 18 to assemble tubing 18 is received by the connector bore 14 and rested against seat 68 the ferrule 28 and the collet 38 are then slipped along the tubing 18 through their respective bores 30 40 followed by the nut 20 the nut 20 is slipped along the tubing 18 until the nut can threadably engage the connector body 12 note that the ferrule 28 and the collet 38 are aligned so that the collet front face 44 is generally parallel to the ferrule rear face 32 and the ferrule blunt nose 34 will contact the connector body 12 as the nut 20 threadably engages the connector body 12 the ferrule 28 and the collet 38 are drawn toward the connector body 12 at the partially assembled position shown in fig2 the ferrule conical surface 36 is starting to engage.
