Tubular ring lug Cimco 183924

The Cimco 183924 tubular ring lug is a straight electrical connector engineered to provide reliable, low-resistance connections in wiring systems. Constructed from aluminum with copper contact surfaces, this lug combines good conductivity with mechanical durability. Designed for single-unit sale, the tubular shape allows secure crimping and a firm attachment to conductors while the ring terminal ensures a stable bolted connection to posts or studs.

Advantages

The combination of aluminum body and copper contact areas offers improved current transfer compared with plain aluminum terminals while maintaining resistance to deformation under crimping. The straight tubular design supports consistent crimp profiles and minimizes the risk of loose strands. A ring termination provides a solid mechanical and electrical connection when fastened, reducing the chance of intermittent contact in vibrating or thermally cycling environments.

Key specifications

How to use

Select a lug size that matches the conductor cross-section. Strip the insulation to the appropriate length, insert the conductor fully into the tubular barrel, and perform a crimp with a suitable crimping tool or hydraulic crimper designed for tubular terminals. Verify that the crimped connection is mechanically secure and that no loose strands are present. Attach the ring to the stud or bolt and tighten to the recommended torque for the stud and conductor size to ensure a low-resistance, vibration-resistant connection.

Recommendations

Ensure compatibility between conductor material and the lug; where dissimilar metals are joined, use appropriate anti-oxidation compound or a transition connector per installation standards. Inspect crimp quality visually and with a pull test where required, and apply the correct torque to bolted connections to maintain electrical integrity over time.
