Parts Desk Insights
Best Use Case: Use these terminals when you need a #10 ring lug style termination on 22-18 AWG marine wiring, with the heat-shrink adhesive helping seal the connection after crimping.
Common Issues: Most connection problems come from incorrect crimping or wire gauge mismatch—confirm the wire falls within the 22-18 AWG range and ensure the adhesive-lined tubing fully shrinks to cover the crimp for a proper seal.
