Terminal ring connector BLOW 43-011# insulated screw 3.7 mm for 4.3 mm cable

Insulated ring terminal connector BLOW 43-011# is designed to provide a reliable screw-type connection for electrical cables with an outer diameter of approximately 4.3 mm. The ring's internal diameter is 3.7 mm, enabling a secure fit onto studs and screw terminals. The insulated sleeve reduces the risk of accidental short circuits and offers basic mechanical strain relief for the conductor joint. The connector is suitable for crimping to a prepared conductor and intended for use in automotive, industrial and household wiring installations where a firm screw connection is required.

Advantages

The insulated construction provides electrical isolation around the crimped area, reducing the likelihood of contact with adjacent conductive parts. The 3.7 mm ring internal diameter is matched to common screw terminal sizes, ensuring consistent mechanical retention. The terminal is compatible with standard crimping tools and offers a compact, space-saving form factor for tight wiring spaces. Its design supports both electrical conductivity and mechanical stability when correctly installed.

Suitable for

• Fastening cables to screw terminals on automotive batteries and chassis.
• Connection points in industrial control panels and equipment.
• Household electrical appliances and repair tasks requiring insulated ring connections.
• Any application where a crimped insulated ring terminal is preferred for secure screw fastening.

Key specifications

• Ring internal diameter: 3.7 mm
• Intended cable outer diameter: 4.3 mm
• Connection type: insulated ring for screw fastening
• Mounting method: stud or screw terminal
• Termination method: crimp

How to use

Strip the cable insulation to expose the conductor length recommended for the terminal. Insert the conductor fully into the terminal barrel, then use an appropriate crimping tool to compress the barrel around the conductor until a secure mechanical and electrical connection is achieved. Slide the insulated sleeve into position to cover the crimped area if not pre-assembled. Mount the ring onto the stud or screw and tighten to the manufacturer's recommended torque for the connected terminal size to ensure good contact without deforming the ring.

Usage recommendations

Use a matched crimping tool for insulated terminals and verify the crimp quality by visual inspection and, if necessary, a pull test. Select the correct ring terminal size for the conductor cross-section and the screw/stud diameter. Avoid excessive torque that can damage the ring or conductor; follow the equipment manufacturer's torque specifications where available.
