Electrical Connectors

Build-Your-Own Weatherproof DC Connectors

Configure a connector for your application by combining housings with pins and sleeves for different wire sizes. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Weatherproof DC Connector Sets

Each set includes one plug and one socket. These connectors withstand moisture, harsh engine fluids, and high temperatures. Also known as weather-pack connectors.

Ready-to-Use Weatherproof DC Connectors

Quickly replace or add connectors to an existing wiring system—connectors come assembled with wire leads already installed. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Deutsch-Style DC Connectors

Use these connectors in vehicles and other agricultural and construction equipment. They have a sealed nylon housing that resists dust and temporary submersion.

Panel-Mount Deutsch-Style DC Connectors

Install these connectors in panels, enclosures, and bulkheads to join equipment with compatible Deutsch-style DC connectors.

Build-Your-Own Molex Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. Use them with standard Molex connectors.

Terminals

Noninsulated Pin Terminals

These solid pins make it easier to insert stranded wire into screw-clamp connections.

Insulated Pin Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Heat-Shrink Snap-Plug Terminals

When heat is applied, the insulation shrinks and creates a seal that keeps out water, salt, and contaminants.

Noninsulated Snap-Plug 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.

Insulated Snap-Plug Terminals

A plastic cover provides electrical insulation.

Deutsch-Style Power Cords

Use these cords in vehicles and other agricultural and construction equipment.

Fasteners

Push-On External Retaining Rings

No groove required—press these rings onto the end of a shaft for a firm grip.

Push-On Retaining Caps

Use these caps to hold components in place and protect shaft ends.

Rectangular Push-On External Retaining Rings

Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Single-Turn Spiral External Retaining Rings

Slide these rings into place with one twist—no tools required—for applications with high thrust loads.

Side-Mount External Retaining Rings

Also known as E-style rings.

Wide-Grip Side-Mount External Retaining Rings

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

Push-On Internal Retaining Rings

No groove required—these rings have teeth that firmly grip the bore.

Single-Turn Spiral Internal Retaining Rings

Slide these rings into place by hand with a single twist for applications with high thrust loads.

Rectangular Push Nuts for Tapping Screws

Rectangular Push Nuts

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.

Side-Mount External Retaining Ring Assortments

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.

Tag Rings

Loop these rings onto tags.
