• Funnel barrel construction for easy wire insertion.
• Nylon-insulated terminals with grip feature a brass sleeve for strain relief and vibration protection.
• Non-slip ridge for proper tool positioning.
• Beveled leading edge for easy wire insulation entry.

Barrel Styles:

• Non-Insulated (Butted Seam, Brazed Seam)
• Vinyl Insulated (Brazed and Butted Seams)
• Nylon Insulated (Butted Seam with Insulation Grip)
• Heat Shrink (Brazed Seam)

High Temperature Terminals and Connectors:

• Constructed of steel with nickel plating.
• Continuous use rating of 900F (482C).
• Suitable for ovens, motors, light fixtures, and other high-temperature applications.
• No applicable UL or CSA standard for high temperature steel parts.

Insulation Grip: Provides a second crimp on wire insulation for additional wire strain relief, excellent for high vibration applications.

Disconnects:

• Insulated: Barrel insulation only.
• Fully Insulated: Insulated from barrel to receptacle/tab.
