Proseal Butt Splice Connector Jar


Master Appliance's butt connectors are the first choice of electricians, auto repair specialists, and other professionals that demand high performance. You will be hard-pressed to find superior crimp and seal splice connectors on the market, and every butt splice connector we supply is crimped for mechanical reliability, soldered for strength and conductivity, and heat-sealed for superior durability. We offer three different gauge sizes to choose from: 10 – 12 AWG (Yellow), 14 – 16 AWG (Blue), and 18 – 20 AWG (Red). All crimp butt connectors are color-coded with wire gauge imprint, so you can quickly and easily identify the correct part for the job. To ensure better wire contact, less voltage drop, and better current flow, all Proseal butt splice connectors are designed with brazed seam rings and spades.

In terms of durable insulation and watertight connections, our butt connectors set the standard for quality and consistent performance. All the heat-shrink tubing we supply is made of entirely of translucent, adhesive-lined polyolefin to allow for easier visual inspection and prevention of wire corrosion. Plus, the tubing that comes with our splice connectors will not reduce in length, so you can count on superior wire support and strain relief wherever it is needed most. Proseal butt splice connectors are free of lead and have 89 pounds of tensile strength, so you can maintain the original integrity of wire connections and wiring harnesses that conform with OEM standards. If you have any questions about our crimp butt connectors or need help finding the right butt splice connector for the job, please don't hesitate to contact us today.
