Conversions Tech Tinned Copper Compression Lug – 4/0 AWG, 5/16″ Stud
The Conversions Tech Tinned Copper Compression Lug is a seamless tubular, heavy-duty electrical connector engineered for 4/0 AWG copper conductors and a 5/16″ stud interface. Manufactured from high-purity copper and fully tin plated, this lug delivers excellent electrical conductivity, corrosion resistance, and long-term mechanical stability in high-current power distribution applications.
Its seamless barrel construction supports uniform compression during crimping, helping reduce electrical resistance while improving pull-out strength and vibration resistance. This lug is ideal for industrial power systems, battery cables, renewable energy, grounding conductors, and heavy-equipment electrical assemblies.
Key Features
- Seamless tubular copper barrel for uniform crimp compression

Dimensions
Dimensions vary by stud size. If you want the exact 5/16″-stud dimensions in the same format (L, W, T, TT, BL, ID, Pad Length, Strip Length), send the highlighted 5/16″ row/spec sheet and I’ll match it line-for-line.
Typical Applications
- Battery cable terminations
- Power distribution and bus bars
- Renewable energy systems
- Industrial equipment wiring
- Grounding and bonding conductors
Installation Notes
- Use a hydraulic or dieless compression crimp tool rated for 4/0 AWG copper lugs
- Strip conductor insulation to the specified strip length before crimping
- Do not use with aluminum conductors
- Seal with adhesive-lined heat shrink for outdoor or corrosive environments
Frequently Asked Questions (FAQs)
What wire size is this compression lug designed for?
This lug is designed specifically for 4/0 AWG copper conductors.
What stud size does this lug fit?
It is designed for a 5/16″ stud, ensuring a secure bolted connection.
Is this lug seamless or welded?
This is a seamless tubular compression lug, providing uniform crimping and strong mechanical performance.
Why is this lug tin plated?
Tin plating improves corrosion resistance, reduces oxidation, and helps maintain stable electrical contact over time.
What voltage rating does this lug support?
This lug is rated for applications up to 600 volts.
What crimping tool should be used?
Use a hydraulic or dieless compression crimp tool rated for 4/0 AWG copper lugs and follow the tool manufacturer’s die/index guidance.
Can this lug be used outdoors?
Yes. For best results in wet or corrosive environments, seal the termination with adhesive-lined heat shrink.
Is this lug suitable for aluminum wire?
No. This lug is designed for copper conductors only. Use an AL/CU-rated connector for aluminum conductors.
What applications is this lug best suited for?
Ideal for battery cables, power distribution, grounding systems, renewable energy installations, and industrial electrical assemblies.
Do the dimensions change between 3/8″ and 5/16″ stud versions?
Yes—stud size typically changes the ring hole and can affect tongue geometry. If you share the 5/16″-stud spec row, I can populate the exact dimension table.
