Sta-Kon F9013 NON-INS FERRULE 14, 2.5 MM2, LG .47

The F9013 wire ferrule is sized for 14 AWG conductor, which is the 2.5 mm2 metric equivalent called out in the part description. Barrel length is .47 inch. If you are terminating 16 AWG or 12 AWG strands you need a different ferrule size, since the crimp barrel is dimensioned for one conductor cross-section and an undersized or oversized wire will not hold a reliable crimp.

Bare. The F9013 is a non-insulated ferrule, so there is no plastic collar on the back end to color-code the size or to support the wire insulation. That is what you want inside a terminal block or a spring-cage connector where the clamp depth is tight and an insulated collar would get in the way. If you need strain relief at the insulation or color-by-size identification on a control panel, order an insulated ferrule instead.

Copper. The F9013 ferrule body is copper, which makes it a copper-to-copper termination on stranded copper wire. Do not use it on aluminum conductor, because a copper barrel crimped onto aluminum is a dissimilar-metal joint and aluminum terminations require a connector rated and marked for that service.

A ferrule gathers the strands of a 14 AWG stranded conductor into one solid copper pin so the screw or spring clamp bears on the barrel rather than on loose strands. That keeps strands from splaying out of the terminal, from being cut by the screw, and from loosening as the joint relaxes. On control panels and VFD terminations it is standard practice, and many European terminal blocks are specified that way. The F9013 gives you a .47 inch barrel to seat in the clamp.

Order Sta-Kon F9013. That manufacturer part number is the 14 AWG / 2.5 mm2 non-insulated copper ferrule with a .47 inch length. There is one configuration of it, so no finish, color, or length suffix needs to be specified.

Ferrules are crimped with a ferrule crimper, not with a standard insulated-terminal tool. The jaws form a square, hex, or trapezoid profile around the full barrel length so the copper compresses evenly onto the strands. A ferrule crimper with a die for 2.5 mm2 (14 AWG) is what matches the F9013. A tool that only has nest profiles for insulated ring and fork terminals will deform the barrel and leave a loose joint.
