Tubular ring lug Cimco 181540 Copper plating Straight 501 pcs

Cimco 181540 is a tubular ring lug designed for creating reliable, low-resistance connections in electrical assemblies. The lug has a straight tubular shape with copper plating to improve conductivity and resist corrosion. Supplied in a pack of 501 pieces, it is intended for repetitive or bulk installation tasks where consistent mechanical and electrical performance is required.

Advantages

The copper plating provides improved electrical conductivity and offers corrosion protection compared with untreated bases. The tubular design ensures a secure crimped connection with predictable mechanical strength and uniform contact area. Supplied in a large quantity pack, the product reduces the need for frequent reordering and supports batch wiring operations. The straight configuration simplifies insertion into terminal blocks and mating components.

Suitable for

• Mass termination and bulk wiring in control panels
• Automotive harness repairs and assembly
• Industrial machinery electrical connections
• Electrical maintenance and service kits
• Any application requiring circular ring terminations for bolted connections

Key specifications

• Connector type: tubular ring lug, straight orientation
• Material finish: copper plating for enhanced conductivity
• Pack quantity: 501 pieces suitable for bulk use
• Intended use: crimp termination for stranded or solid conductors
• Typical mechanical characteristics: designed for secure crimp and bolted ring connections

How to use

Select a lug size appropriate to the conductor cross-section and the bolt or stud diameter of the mating terminal. Strip the conductor to the specified length, insert the conductor fully into the tubular opening, and crimp with a suitable crimping tool or press rated for the lug size. After crimping, inspect the joint for a solid, deformation-free crimp and verify electrical continuity. Fit the ring over the bolt or stud and secure with the proper nut and washer as required for the application.

Usage recommendations

Use a matched crimping die and calibrated tool to achieve reliable mechanical strength and low contact resistance. Where environmental exposure is expected, consider additional protection such as insulating sleeves, heat-shrink tubing, or conformal coatings to extend service life. Store the pack in a dry environment to avoid contamination of the copper-plated surfaces.
