Pico Wiring Heat Shrink Butt Connectors Waterproof

Pico Wiring heat shrink butt connectors are crimp-style wire splice connectors. Each one has an adhesive-lined nylon heat shrink sleeve. They join two wires end to end and seal the splice against moisture and corrosion. They suit automotive, marine, RV, trailer and powersports wiring repairs and upgrades where a waterproof butt splice is needed.

Key Features:

• Seamless copper barrel: gives a solid crimp with no barrel splitting.
• Adhesive-lined nylon heat shrink sleeve: the inner adhesive wall melts as heat is applied, fills voids around the wires, and cools into a permanent waterproof, corrosion-resistant seal.
• Translucent sleeve: lets you check that the wire is seated correctly, and shrinks about 30% faster.
• Wire stop and flared sleeve: the wire stop prevents over-insertion, and the flared sleeve makes it easier to feed in the wire.
• Electrical and mechanical ratings: maximum electrical rating of 750 volts and tensile strength of 4000 psi.
• Temperature range: insulation shrinks at 212°F (100°C). Operating temperature is -67°F to 257°F (-55°C to 125°C).

Simple Installation: Insert a stripped wire into each end of the connector barrel and crimp firmly. Apply heat slowly until the adhesive softens and the outer sleeve shrinks. Let it cool for a sealed connection that resists moisture and corrosion.

Choose the connector that matches your wire gauge from the variants listed on this page. Each gives a dependable, sealed splice for harsh, wet or high-vibration environments.
