Sta-Kon RB854M EXP INS NYL RNG TRM 18-14 No6 MYLAR

The RB854M is sized for 18 to 14 AWG stranded or solid copper wire. Blue insulation is the standard color code for that range, and this terminal's barrel is blue, so you can identify it in a mixed bin without reading the stamp. If you are terminating 16 AWG control wire or 14 AWG branch wiring in a panel, this is the right barrel size; 12-10 AWG needs a yellow terminal instead.

A ring terminal like the RB854M has a closed tongue, so once the screw is tightened the wire cannot back out even if the screw loosens. That is why inspectors and spec writers call for rings on vibration-prone equipment, motor connections, and grounds. A fork or spade terminal can be slipped out from under a partially loosened screw, which makes it faster to service but less secure. If the connection is a ground or carries vibration, use the ring.

Nylon. Nylon insulation resists abrasion, crushing in tight panel bends, and oils and solvents better than vinyl, and it handles higher temperatures, which is why it is the usual choice for industrial control panels and MRO work rather than light automotive use. The sleeve on the RB854M is nylon and color-coded blue.

It is an expanded-insulation nylon ring terminal, meaning the insulating sleeve extends back over the wire insulation to support the conductor behind the crimp. That extra support is what keeps strands from flexing and fatiguing right at the barrel mouth, which matters on panel doors and anywhere the harness moves.

Order Sta-Kon RB854M. That single manufacturer part number covers the blue nylon insulated ring terminal for 18-14 AWG wire with a No. 6 stud tongue; there are no finish or size options to specify.

Use an insulated-terminal crimper with the blue 18-14 AWG nest, matched to the Sta-Kon barrel. Sta-Kon terminals are designed around Thomas and Betts Sta-Kon tooling, and the color-coded die positions on a standard insulated crimper correspond to the blue 18-14 range. Do not use an uninsulated open-barrel die; it will cut the nylon sleeve.

Country of origin on the RB854M is the United States. If you are procuring for a government, education, or federally funded project with domestic-sourcing language, that is the data point your submittal needs.
