Insulated ring terminal for 16-22 AWG, #8 stud
The 2-34148-4 is the red-coded, 16-22 AWG member of TE's Plasti-Grip insulated ring terminal line, terminated to a #8 stud. The PVC insulation sleeve accepts wire insulation diameters from 0.105" to 0.200" (2.67mm to 5.08mm). Tin-plated copper contact, serrated termination for grip on the conductor bundle.
Plasti-Grip vs non-insulated Solistrand peers
The Plasti-Grip 2-34148-4 is an insulated ring terminal; the Solistrand 1377172-7 and 133521-1 are non-insulated, bare-metal terminals for the same #8 stud size and similar wire ranges (14-16 AWG and 18-22 AWG respectively). The insulation sleeve on the Plasti-Grip adds strain relief and prevents accidental shorting to adjacent conductors — a difference that matters when the termination sits in a crowded panel or near a grounded chassis.
