Buying advice

When selecting butt terminals, consider the wire gauge range, insulation material, and crimping tool compatibility. Nylon insulated terminals offer better heat resistance, while vinyl is more flexible. For high-vibration environments, look for braided seam construction. Always check the temperature rating. Use a ratcheting crimper for consistent results.
