A fast, easy and waterproof way to join wiresMarine grade butt connectors make quick work of joining wires; and unlike their automotive counterparts they are able to stand up to the harsh marine environment. Ancor heat shrink connectors offer a watertight seal. A heat activated adhesive built into the sleeve of the heat shrink tubing seals the wires from the harsh marine environment and provides vibration and strain relief. The barrels are designed to tightly grip the wire with minimal effort. Wire specific sizing assures a strong connection. Spend less time working on your boat and more time out on the water.The Ancor Single Crimp Ratcheting Wire Terminal Crimper produces the proper crimp every time and gives you the confidence of a secure connection. ABYC (American Boat and Yacht Council) guideline 11.14.3.8 recommends the use of ratcheting same-branded crimpers.Key FeaturesHeat activated adhesive is built into the sleeve of the heat shrink tubingShrinks to form a watertight sealTinned for corrosion resistancePure copper for maximum current flowBrazed seam for maximum strengthDifferent from automotive terminals by being designed for marine environmentInsulators are easy to crimp and will not splitBarrels are designed to tightly grip wires with the least amount of effortUL 486C listed and CSA recognized
