WHAT MAKE MASTER SOLDERSEAL® HEAT-SHRINK CONNECTORS BETTER


MAKE ELECTRICAL CONNECTIONS FAST & RELIABLE – If you perform routine work on electrical circuits and wire terminals, heat-shrink connectors are must-have accessories that simplify and speed up any application. Master’s Solderseal® heat-shrink connectors are lead-free and feature 102 lbs of tensile strength, ensuring lasting integrity of wire connections and wiring harnesses that meet strict OEM standards.
VERSATILE KIT OPTIONS
TWO ASSORTMENTS AVAILABLE – Choose from our compact MiniPak, which includes an assortment of 10–12 AWG (Yellow), 14–16 AWG (Blue), 18–20 AWG (Red), and 22–24 AWG (Red) connectors for smaller applications—or our large 135-piece assortment that keeps you fully stocked for future projects.
SUPERIOR MATERIALS & DESIGN
HIGH-QUALITY HEAT-SHRINK TUBING – Each Solderseal® connector features translucent, adhesive-lined polyolefin tubing that allows easy visual inspection, prevents wire corrosion, and provides a water-resistant seal. Our shrink tubing maintains its full length after heating to deliver better insulation, superior wire support, and strain relief.
BUILT-IN SOLDER & FLUX FOR EFFICIENCY
PRE-MEASURED SOLDER & FLUX – Every connector includes low-temperature, pre-measured solder and flux, giving you greater tensile strength, superior current flow, and consistent conductivity. Solderseal® connectors are soldered for strength and heat-sealed for durable insulation—ideal when traditional soldering is difficult or time-consuming.
APPLICATIONS
- Automotive and marine wiring
- Electrical circuit repair and maintenance
- Industrial and OEM wiring harnesses

If you perform routine work on electrical circuits and wire terminals, heat-shrink connectors are must-have accessories that can help you make any kind of electrical application quick and easy to complete. Solderseal heat-shrink connectors are free of lead and have 102 pounds of tensile strength, so you can maintain the original integrity of the wire connections and wiring harnesses that conform with OEM standards. We offer two different solder and heat-seal connector kits to choose from. MiniPaks come with an assortment of 10 – 12 AWG (Yellow), 14 – 16 AWG (Blue), and 18 – 20 AWG (Red) Solderseal connectors as well as 22 – 24 AWG (Red) to suit oversized applications. Alternatively, you can stock up for future applications by choosing our large assortment with over 135 pieces to suit any need.
Master's heat-shrink tubing is made of translucent, adhesive-lined polyolefin to allow for easier visual inspection, prevent corrosion of wires, and provide a water-resistant seal. Furthermore, our heat-shrink tubing will not reduce in size, providing better insulation along with superior wire support and strain relief. Where soldering may be too tough, Solderseal heat-shrink connectors may be the ideal solution, because they come fully equipped with pre-measured solder and flux to ensure greater tensile strength and superior current flow. All Solderseal heat-shrink connectors are soldered for strength and conductivity, and heat-sealed for durable insulation you can count on. If you have any questions about our Solderseal connector assortment kits, please feel free to contact us for additional information or further assistance.
