Description

Ancor 311425 heat shrink ring terminals are marine-grade electrical terminals for 16–14 AWG wire with a 1/4″ stud size. These blue ring terminals use adhesive-lined heat shrink insulation to help seal the crimped connection against moisture, salt water, oil, fuel, and other marine contaminants while adding strain relief at the wire connection. Each package includes 25 terminals for marine wiring, helm, battery, panel, and accessory installations where a secure ring terminal connection is required.

Application Compatibility

These terminals are suitable for marine DC wiring applications using 16–14 AWG stranded wire and a 1/4″ post, stud, or screw connection. Common uses include battery switch wiring, fuse blocks, terminal blocks, helm wiring, bilge pump circuits, lighting circuits, electronics wiring, and other boat electrical connections where a sealed ring terminal is preferred.

Fitment Notice

This is a wiring terminal, not an engine-specific part. Confirm the wire gauge, stud size, terminal clearance, and circuit requirements before ordering. These are intended for 16–14 AWG wire and 1/4″ mounting studs; use a different Ancor terminal size if the wire gauge or stud size is different.

When This Part Needs Replacement

Replace ring terminals when they are corroded, loose, overheated, cracked, poorly crimped, exposed to moisture intrusion, or no longer holding the wire securely. Terminals should also be replaced during wiring repairs when the old connection shows green corrosion, broken strands, heat damage, or weak continuity.

Installation Notes

Strip the wire to the correct length, insert it fully into the terminal barrel, and crimp with a proper marine-grade crimping tool. Apply controlled heat evenly to shrink the tubing until the adhesive flows and seals around the wire insulation. Avoid overheating the sleeve, and always support the wire so the terminal is not carrying unnecessary strain.

Parts Desk Insight

The two details to match are wire size and stud size. A heat shrink ring terminal that fits the wire but has the wrong ring diameter can create a poor connection or make installation awkward, so confirm both 16–14 AWG and 1/4″ stud before ordering.
