BLOW connector ring insulated with screw 3.7 mm for 4.3 mm cable

Insulated ring terminal from BLOW with a 3.7 mm ring diameter designed for use with 4.3 mm cable. This connector provides a secure mechanical and electrical connection through screw fastening and features insulation that covers the crimped area to reduce the risk of short circuits and improve handling safety. The ring-style terminal is suitable for applications where a reliable screw-mounted connection is required and where insulated protection around the conductor is preferred.

Advantages

The insulated ring terminal combines a metallic contact surface for stable conductivity with a molded insulating sleeve that prevents accidental contact and reduces corrosion risk at the crimp. The screw-mounted ring ensures a firm mechanical attachment to terminals or studs, maintaining electrical continuity under vibration or movement. Its size matches commonly used 4.3 mm cable ranges and supports straightforward crimping with standard tools.

Suitable for

• Automotive wiring and battery connections
• Electrical repairs and household wiring
• Industrial control panels and terminal blocks
• Maintenance tasks requiring screw-mounted connections

Key specifications

• Ring inner diameter: 3.7 mm
• Compatible conductor size: for use with 4.3 mm cable
• Connection method: screw-mounted ring terminal
• Insulation: molded sleeve covering crimp area
• Material: conductive metal contact with insulating polymer sleeve

How to use

Strip the cable insulation to the appropriate length, insert the stripped conductor into the terminal barrel, and crimp using a suitable crimp tool sized for the connector. Position the ring over the terminal stud or screw and secure with the appropriate screw or nut, ensuring firm mechanical contact without over-tightening. Verify electrical continuity and that the insulation fully covers the crimped area to avoid exposed conductor.

Usage recommendations

Use the connector with correctly sized cable and a compatible crimping tool to ensure a reliable joint. Choose corrosion-resistant screws or washers in environments exposed to moisture, and regularly inspect connections in high-vibration applications.
