  • Product colorBlack
  • Secure connections for automotive and marine wiring using tinned copper ring terminals
  • Waterproof and dustproof seal from 3:1 heat-shrink tubing with adhesive lining
  • Pure copper construction ensures excellent conductivity and long-term durability
  • Flame-retardant PVC insulation sleeve adds safety during electrical installations
  • 260-piece assortment covers AWG 22-10 with #10, 1/4", 5/16" and 3/8" stud sizes

Marine Grade Ring Terminal Assortment

This 260-piece kit supplies insulated ring terminals in three colours and four stud sizes, covering wire gauges from AWG 22-10. It is designed for installers who need a single box that handles automotive, marine and general low-voltage wiring jobs.

Heat Shrink Seal and Copper Conductivity

Each terminal uses pure copper with a 3:1 shrink ratio tubing that seals against water and dust when heated. The flame-retardant PVC sleeve adds insulation, while the tinned finish resists corrosion in damp environments.

260 Terminals Across Four Stud Sizes

The box contains #10, 1/4", 5/16" and 3/8" ring terminals colour-coded for AWG 22-16, 16-14 and 12-10 ranges. Buyers needing larger lugs, spade ends or a built-in crimper must choose a different kit.

Questions about this item

How do I install these marine grade heat shrink ring connectors and which step is most often done wrong?

Strip the wire to the correct length for AWG 22-10, crimp the tinned copper barrel with a proper ratchet tool, then apply heat evenly until the 3:1 shrink tubing seals; the step most often done wrong is using insufficient heat so the adhesive liner does not fully melt and seal.

What maintenance or replacement will these 260PCS connectors need later?

The heat shrink seal is permanent; inspect each ring terminal periodically for corrosion on the #10, 1/4", 5/16" or 3/8" studs and replace any connector where the tinned copper shows green oxidation or the tubing has cracked.

What limit appears first under sustained use?

The 3:1 shrink tubing adhesive liner can degrade if the joint regularly exceeds its temperature rating, so the waterproof seal fails before the tinned copper barrel or the PVC insulation sleeve.
