About Quick-Disconnect Terminals

Quick-disconnect terminals provide fast and secure connections for your wiring. Because they are easy to connect and disconnect, these terminals are convenient for applications that require frequent repair or replacement. When an application calls for a 1/4" quick-disconnect, choose a terminal with a 0.250" tab width.

Insulated Snap-Plug Terminals

Single-Crimp Female

Single-Crimp Male

Double-Crimp Female

Double-Crimp Male

The connection on these terminals is completely covered with insulation when mated, leaving no metal exposed and preventing short-circuiting with nearby wire. Also known as bullet terminals, these have a round tab that requires less space than the flat tab found on most quick-disconnect terminals. Use a crimper (not included) to install wire.

Double-crimp terminals have a long barrel that can be crimped to wire insulation for strain relief and an extra-tight grip in high-vibration applications.

Nylon-insulated terminals are more durable and resist chemicals better than vinyl-insulated terminals.

Also known as bullet terminals, these have a round tab that requires less space than the flat tab found on most quick-disconnect terminals. Because they are noninsulated, you can easily inspect the wire connection. Use a crimper (not included) to install wire.

Heat-Shrink Snap-Plug Terminals

Female

Male

When heat is applied, the insulation shrinks and creates a seal that keeps out water and contaminants. Also known as bullet terminals, these have a round tab that requires less space than the flat tab found on most quick-disconnect terminals. Use a crimper (not included) to install wire.

Female terminals have a fully insulated connection tab, so no metal is exposed when they are mated.

Solder-Loaded Heat-Shrink Snap-Plug Terminals

Female

Male

When heated, the enclosed solder in these terminals melts forming the most secure and electrically conductive connection we offer. The plastic insulation also shrinks when heated, sealing out water and contaminants. Also known as bullet terminals, these terminals have a round tab that takes up less space than the flat tabs on most quick-disconnect terminals.

Female terminals have a fully insulated connection tab, so no metal is exposed when they are mated.

Tap-to-Connector Insulation-Piercing Wire Taps and Plugs

Snap Plug

Tap a wire or add a finished terminal to the end of a wire. The parallel taps quickly connect to your wire without stripping the wire first. Squeeze the tap with standard pliers and the U-shaped contact pierces the insulation and grips the wire. Insert a snap plug into the parallel tap. Parallel tap and snap plug are sold separately.
