Ancor 22-18 Butt Connector Heat Shrink Red 250 Pack Jar

The Ancor 22-18 Butt Connector Heat Shrink Red 250 Pack Jar is the professional-grade solution for reliable electrical connections in marine, automotive, and industrial wiring applications. Designed for wire gauges between 22 and 18 AWG, these heat shrink butt connectors deliver secure, weatherproof terminal connections that eliminate the risk of corrosion and connection failure. This 250-piece jar is ideal for technicians, installers, and maintenance professionals who demand consistent quality across high-volume projects.

Each connector combines a tinned copper barrel with integrated heat shrink tubing that seals and insulates the joint after crimping and heating. The red color coding provides immediate visual identification of wire gauge compatibility, reducing installation errors in the field. The heat shrink element shrinks at approximately 221°F, creating a tight, moisture-resistant seal that protects against oxidation, salt spray, and harsh environmental exposure—critical features for marine and outdoor electrical systems. Ancor's precision engineering ensures minimal voltage drop and maximum contact integrity even under vibration and thermal cycling.

Technicians installing wiring harnesses on boats, RVs, trucks, and industrial equipment will appreciate the convenience of the reusable clear plastic jar with flip lid, which keeps connectors organized and visible on the workbench or in a service vehicle. Whether you're splicing power distribution circuits, repair harnesses, or creating custom cable assemblies, the 250-count bulk format ensures you won't run short mid-project. These connectors are industry-standard for marine electronics, auxiliary lighting circuits, and any 22–18 AWG application requiring permanent, sealed connections.
