Caliso DK05737 Blue Heat Shrink Ring Terminal Connector

The Caliso DK05737 is a blue heat shrink ring terminal designed for reliable, weatherproof electrical connections in automotive, marine, RV, and powersports wiring applications. The blue color coding identifies compatibility with the industry-standard 16–14 AWG wire gauge range, making it easy to select the correct terminal at a glance.

The ring-style design features a closed loop that slides over a stud or screw and stays securely in place even when the fastener is slightly loose or the connection is subject to vibration. The heat shrink sleeve, when activated with a heat gun, contracts tightly around the wire insulation to form a moisture-resistant, insulated seal that protects against corrosion, abrasion, and vibration-induced fatigue.

Key Features:

• Blue color coding for 16–14 AWG wire gauge identification
• Heat shrink sleeve provides a secure, insulated, moisture-resistant seal
• Ring-style terminal stays in place on studs and screws for a permanent connection
• Suitable for automotive, marine, RV, powersports, and general electrical wiring
• Protects the connection from corrosion, vibration, and abrasion
• Crimp-and-shrink installation for fast, reliable termination

The Caliso DK05737 blue heat shrink ring terminal is an essential component for any wiring harness build, repair, or upgrade where a clean, long-lasting, and environmentally protected electrical connection is required.
