Introduction

Ring connectors provide a reliable way to attach wires to terminal screws in automotive, marine, and household electrical systems.

  • Choose the correct ring diameter to match your terminal screw size.
  • Select insulated or non-insulated versions based on the environment.
  • Verify wire gauge compatibility before crimping for a secure connection.

Browse ring connectors sized for your specific wiring needs.

FAQs

Most ring connectors are made from copper or brass with tin plating for corrosion resistance and conductivity.

Reusing ring connectors is not recommended because crimping can deform the metal and weaken the connection.

Only heat-shrink or fully insulated ring connectors should be used outdoors to protect against moisture and corrosion.

A proper crimping tool matched to the connector size ensures a secure, gas-tight connection without damaging the wire.

Yes, common stud hole diameters include #6, #8, #10, 1/4 inch, 5/16 inch, and 3/8 inch to fit various terminal screws.
