Heat Shrink Butt Splices

Sentry Wiring’s Heat Shrink Butt Splices deliver dependable, weather-resistant connections designed to perform in harsh, high-vibration environments. These premium connectors feature a heat-activated adhesive lining that seals out moisture and corrosion—ideal for fleet vehicles, upfitters, municipal service equipment, and marine or outdoor wiring.

We proudly offer Opti-Clear splices, which provide a transparent heat shrink sleeve for easy visual inspection of the crimp and wire engagement—so you know your connection is solid and secure. Available in a range of wire gauge sizes, these splices ensure a strong mechanical bond, excellent conductivity, and long-term reliability.

Trusted by professionals who value performance, clarity, and confidence in every connection.
