Terminal ring connector BLOW 43-016# insulated, stud 5.3 mm, cable 4.3 mm

The BLOW insulated ring terminal connector 43-016# is an electrical crimp terminal designed for fastening a conductor to a 5.3 mm stud. It accepts cables up to 4.3 mm in diameter and combines a tin-plated metal ring with a molded insulating sleeve to provide both an electrical connection and protection against accidental contact and short circuits. The compact construction and standardized stud diameter make this terminal suitable for a wide range of automotive, industrial and general electrical applications where a reliable screw or bolt connection is required.

Advantages

This insulated ring terminal offers a secure mechanical and low-resistance electrical connection when properly crimped. The molded insulation reduces the risk of exposed conductors and improves handling safety during installation and maintenance. The metal ring's flat profile ensures stable contact on a 5.3 mm stud, while the construction is compatible with common crimping tools, enabling repeatable, consistent terminations.

Suitable for

• Automotive battery and accessory connections that use a 5.3 mm stud
• Industrial control panels and terminal blocks requiring bolted connections
• General electrical installations where insulated ring terminals improve safety

Key specifications

• Stud diameter compatibility: 5.3 mm
• Maximum conductor diameter: 4.3 mm
• Connector type: insulated ring terminal
• Construction: metal ring with molded insulating sleeve
• Typical applications: automotive, industrial, electrical installations

How to use

Select a ring terminal sized for a 5.3 mm stud and for your conductor diameter (up to 4.3 mm). Strip the conductor insulation to the recommended length so the bare conductor fills the crimp barrel. Insert the conductor into the terminal barrel and crimp using an appropriate hand or bench crimping tool, ensuring a solid mechanical deformation and electrical contact. Position the ring over the stud and secure with the appropriate nut or bolt, then verify tightness and electrical continuity.

Usage recommendations

Use an approved crimping tool sized for insulated terminals to achieve a reliable crimp. Verify that the conductor size does not exceed 4.3 mm and that the stud is 5.3 mm to ensure correct fit. For environments exposed to moisture or vibration, inspect terminations periodically and consider additional sealing or locking hardware as needed.
