Conversions Tech Tinned Copper Compression Lug – 2/0 AWG, 3/8″ Stud
The Conversions Tech Tinned Copper Compression Lug is a seamless tubular, heavy-duty electrical connector engineered for 2/0 AWG copper conductors and a 3/8″ 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.
The seamless barrel construction ensures uniform compression during crimping, reducing electrical resistance while improving pull-out strength and vibration resistance. The 3/8″ stud ring is ideal for battery terminals, bus bars, grounding points, inverters, and industrial distribution blocks where standard hardware sizes are used.

Frequently Asked Questions (FAQs)
What wire size is this compression lug designed for?
This lug is designed specifically for 2/0 AWG copper conductors.
What stud size does this lug fit?
It is designed for a 3/8″ stud and uses a nominal 0.390″ stud hole.
Is this lug seamless or welded?
This is a seamless tubular compression lug, providing uniform compression 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 600V.
What crimping tool should be used?
Use a hydraulic or dieless compression crimp tool rated for 2/0 AWG copper lugs and follow tool manufacturer guidance.
What is the recommended strip length?
The recommended strip length is 0.790″ to ensure full conductor insertion.
Can this lug be used outdoors?
Yes. For wet or corrosive environments, sealing with adhesive-lined heat shrink is recommended.
Is this lug suitable for aluminum wire?
No. This lug is designed for copper conductors only.
Do dimensions change across stud sizes?
Within this 2/0 AWG seamless tubular series, the primary dimensional change is the stud hole size. Always verify hardware clearance for your application.
