D Shaped Ring Terminal: Partially Insulated, 18 to 14 AWG, Crimp Connection MPN:14RB-4

The d shaped ring terminal is a popular option for making connections in electrical circuits and features a partial insulation that helps protect against accidental short circuits while still allowing for easy connection to a wire. It's made of high-quality, tinned copper material making it strong and corrosion resistant, perfect for environments exposed to moisture or chemicals, available in size ranging from 18 - 14 AWG suitable for wires of varying thicknesses; the insulation color may vary from yellow or red depending on the type but the crimping function is identical so users won't have difficulty finding compatible options when changing sizes. The d shaped design offers more space within the terminal to increase surface area between wire and the connection resulting in a secure and solid connection providing efficient power transfer, eliminating worries about loose connections which could cause potential safety hazards in circuits or systems!
