Waterproof Electrical Connectors Kit for DIY

At ONSSKI, we don't simply sell tools - we empower DIY enthusiasts, craftsmen, and artisans to unleash their creativity and bring their wildest ideas to life. Whether you're a seasoned pro or a rookie DIY-er, join our family and let's make some magic together.

Our crimp connectors are made with tinned thick red copper barrels and polyolefin heat shrink tubing, ensuring high current flow and minimum voltage drop. The heat shrink tubing creates a cable entrance seal, providing environmental sealing protection and shielding wires and cables from abrasion, cuts, wear, and low-impact conditions.

With a 3:1 shrink ratio, the adhesive inside melts when heated with a heat gun, creating a waterproof and insulated seal that prevents electric leakage and corrosion. This marine-grade heat shrink butt splice can be widely applied in the automotive industry, marine applications, science projects, and household electrical wire connections.

Included in the valuable package are 240 pieces of heat shrink butt connectors that can be used on different sizes of wires, catering to a variety of needs.
