distance of varying width and depth grooves 22 and 24 the crimping tool rotates eccentrically on the coil tubing resulting in lesser penetration at the thick portion of installation clamp 25 and deeper penetration at the thin portion of installation clamp this results in a narrow width and shallow depth at the thin portion of the installation clamp position on the coil tubing and a wider width and deeper depth at the thick portion of the installation clamp position on the coil tubing the crimping tool has a screw type feed mechanism which presses the sections of coil tubing to the desired depth as the roller indenter is pushed against it because the grooves are of varying width and depth they lock with the coil tubing and hence the sections of coil tubing do not rotate relative to the spoolable connector thereby enabling the spoolable connector 10 to effectively transmit torque between the two opposing sections of coil tubing the varying width of the groove acts as a wedge so as to grip the opposing sections of coil tubing rotationally thereby enabling the connector to effectively transmit torque between the opposing sections of coil tubing the varying depth compresses the portions of coil tubing harder on the connector thereby preventing any rotation the varying width and depth grooves 22 and 24 are machined.
