Master's heat shrink tubing is made of translucent polyolefin and lined with adhesive, allowing for easier visual inspection and preventing wire corrosion. The heat shrink tubes are also designed not to reduce in length, creating better insulation along with superior wire support and strain relief. We are committed to delivering professional-quality butt splice connectors with less voltage drop and a better current flow. We supply Multiseal, Proseal, and Solderseal butt splice connectors in different gauge sizes, ranging from 20 to 10 AWG. Each splice connector is crimped for mechanical reliability, soldered for strength and conductivity, and heat-sealed for superior durability. We also provide heat-seal connectors with varying grades of tensile strength, ranging from 89 to 103 pounds.

If you're looking for the finest crimp and heat-seal connector kits on the market, you have come to the right place. All Multiseal, Proseal, and Solderseal kits come equipped with seamless wire connectors, brazed seam rings, and spades, which prevent opening of the connector barrel for a stronger crimp. All tubing is color-coded with wire gauge imprint, so you can easily identify the correct connector for the job. Select heat-seal kits are available in standard assortment packs and butt splice minipacks.
