Dowells Copper Ring Terminal (Crimp-on Cable Lug) is a non-insulated, electro-tin plated EC-grade copper ring lug for high-performance electrical termination in industrial panels, control racks, and automotive wiring. The seamless malleable barrel compresses uniformly under crimping pressure without cracking, creating a cold-weld bond between the copper strands and the barrel wall – no soldering required. The tin plating protects wire joints from moisture and oxidative corrosion. Supplied in packs of 200 pieces, available across 4 variants covering cable cross-sections from 1.5 sqmm to 6.0 sqmm and stud sizes from M4 to M6 – select the correct item code for your wire size and terminal bolt diameter.
Key Features
EC-Grade electrolytic copper: High-purity copper for minimal electrical resistance and maximum conductivity
Electro-tin plated: Full tin coating protects against moisture, rust, and oxidative corrosion
Seamless malleable barrel: Uniform compression under crimping – no cracking under heavy tool pressure
No soldering required: Compression crimp creates a cold-weld bond – faster installation, no heat risk
Ring / circular lug design: Stays anchored to the terminal stud even under vibration in heavy machinery

Installation Notes
Important – Read Before Crimping
Use a calibrated crimping tool: Always use a manual or hydraulic crimping tool matched to the wire thickness – an undersized or oversized die will produce a weak joint
Strip cleanly: Use stripping pliers to remove the outer insulation without scratching the copper core strands
Add insulation after crimping: These lugs are non-insulated – wrap or slide a heat-shrink tube or insulating sleeve over the bare crimp barrel after compression to protect against short circuits and accidental contact
