Part # 315203 Tinned for corrosion resistance. Pure copper for maximum current flow. Brazed seam for maximum strength. Nylon insulator preferred by experts, for Marine Grade resistance to sunlight, water, oil, chemicals, vibration and cut-through damage. Adhesive built into heat shrink tubing shrinks to form a tight seal and the ultimate in vibration and strain relief.
Part # 313203 The flanged tips of these terminals makes it less likely for them to slip off the stud accidentally under marginal connection conditions. Constructed with cross-linked polyolefin tubing which is much stronger than PVC tubing and will not burn like PVC. The heat-activated adhesive lining provides an impervious seal to saltwater, oil, acids, and sunlight, as well as providing strain relief.
