Insulated Butt Connector, Yellow, 12-10 AWG – Philmore 45-3607B-YL

Philmore 45-3607B-YL — Insulated Butt Connectors, Yellow, 12-10 AWG

Philmore 45-3607B-YL insulated butt connectors provide a simple, color-coded solution for joining two conductors with a crimped termination. The yellow insulation identifies the 12–10 AWG range for quick gauge selection on the jobsite and helps streamline inventory and service-van stocking. These sleeves are designed to retain the crimp under vibration and movement, giving consistent mechanical and electrical continuity for repair, retrofit, and OEM harness assembly. The insulated sleeve provides basic electrical isolation and strain relief while keeping the splice compact for use in dense control panels and vehicle harnesses. When used with a quality crimping tool rated for insulated terminals, these connectors speed installations and reduce rework compared with uninsulated or soldered splices. Their common size and straightforward application make them a practical choice for AV installers, low-voltage technicians, and electronics benches where repeatable splices are required. The seamless, color-coded design also aids quick identification during troubleshooting and maintenance.

The simple form factor supports standard wire-preparation and crimping workflows without requiring specialty tooling beyond an insulated-terminal crimper. Tri-Tek Electronics stocks Philmore terminals at our Mesa, Arizona location and ships nationwide to Phoenix, Chandler, Tempe, Gilbert, Scottsdale, Glendale and beyond.

Key Features:

• Color-coded yellow insulation for rapid 12–10 AWG identification
• Insulated sleeve provides electrical isolation and basic strain relief
• Designed for crimp termination to produce consistent mechanical and electrical splices
• Seamless construction for smooth insertion and reliable contact

Specifications:

• Manufacturer: Philmore
• MPN: 45-3607B-YL

Typical Applications:

• Field wire splices for electrical and low-voltage installations
• MRO and service-van stocking for rapid repairs
• OEM wiring harness assembly and control-panel wiring
• Automotive and marine wiring where color-coded gauge identification speeds work

Installation or Use Example:

• An AV installer completes a speaker run, strips both conductor ends to the recommended length, inserts each conductor into the yellow 12–10 AWG insulated butt connector, and uses a ratcheting crimper rated for insulated terminals to form a secure, locked splice before bundling and securing the harness.
