Sierra EC04500-100 Female Fully Insulated Quick Disconnects 16-14 AWG Blue 100-Pack

The Sierra EC04500-100 is a bulk pack of 100 fully insulated female quick disconnect terminals designed for reliable solderless wire terminations in marine, automotive, and powersports electrical systems. Rated for 16-14 AWG wire, these blue nylon-insulated connectors provide a fast, secure push-on connection to matching male spade terminals found on switches, relays, fuse blocks, and other electrical components.

The full nylon insulation sleeve protects each connection against short circuits, abrasion, and electrical isolation failure — critical in the demanding marine environment where vibration, moisture, and corrosion are constant concerns. The color-coded blue housing makes wire gauge identification fast and easy during installation.

Key Features:
