3M 8429-12 Connector Insulator

Product Description

The 3M 8429-12 is a connector insulator designed to provide electrical insulation and protection at wired connection points. Connector insulators of this type are used to cover, seal, and insulate spliced or terminated conductors, preventing accidental contact with energized connections and protecting against moisture and environmental exposure. The 8429-12 is a standard product from 3M's electrical interconnect line and is appropriate for use by licensed electricians and qualified electrical technicians working on low- and line-voltage wiring assemblies.

This connector insulator is suited for residential and light commercial electrical applications where insulated connector coverage is required at wire termination points. Typical install scenarios include panel wiring, junction box connections, and service entry work where exposed terminations must be protected to meet code requirements. It is packaged in a quantity consistent with job-site use.
