12-10 AWG Heat Shrink Butt Connector - 25 PackButt splices are crimp connectors used to safely connect one or more wires to another wire. Step-down butt splices are meant to connect a higher-gauge wire to a lower-gauge wire. They could also be used to connect two or more smaller-gauge wires to a single wire. When selecting which type to get, pay special attention to whether they are epoxy lined or not. Many manufacturers do not line the interior of their butt splices with meltable glue. This epoxy reacts to heat and expands, creating a superior, environmentally sealed connection.Features: Made from tinned copper and various insulations Up to 600 Volts Not applicable to all styles Operating Temp: -55AdegC to 125AdegC UL, CSA, RoHS Compliant Benefits & Protections Impact Resistant Multiple Uses Long Term Protection Easy to Install Specifications: Wire Range: #12-10 AWG Insulation Color: Yellow Max Wire Insulation Outer Diameter (inch): 0.28" Package Size: Twenty-five Specifications: Gauge: 12-10 AWG Heat Shrink: Yes Package Qty: 25 Type: Butt Connectors Box Dimensions: 1"H x 3"W x 4"L WT: 0.1 lbs UPC: 840248206709 Quick Guide (pdf).embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }
