Sea-Dog 18 AWG Black Primary Wire 100ft | 8018012
Sea-Dog 18 AWG Black Primary Wire 100ft | 8018012 — Product description
This is Sea-Dog's 18 gauge primary wire in black, wound on a 100-foot spool. Stranded tinned copper under PVC insulation, so it stays flexible and shrugs off the corrosion that kills bare copper on a boat. Good for light-duty DC runs where you don't need heavy gauge.
Eighteen gauge is the wire you reach for when the load is light. Think LED courtesy lights, gauge backlighting, a small pump, or signal runs where you're not pushing much current. Sea-Dog's 18 AWG primary wire gives you 100 feet of it on a single spool, so you can rig a whole boat's worth of small circuits and still have plenty left in the bin.
The conductor is stranded tinned copper, and that matters on the water. Bare copper corrodes and goes green at the ends, but the tin coating holds it off, so your connections stay clean and your crimps keep their grip for years. The strands keep the wire flexible too, which makes it easier to route behind a console or feed through a rigging tube.
The black PVC jacket is your negative or ground color in most DC layouts. Pull what you need off the spool, cut it to length, crimp, done. It's the kind of everyday wire that's worth keeping on hand.

Frequently asked questions
What is 18 gauge wire good for?
Light-duty DC circuits. Think LED lights, gauge and switch backlighting, small pumps, and low-current signal runs. For higher-draw gear you'll want a heavier gauge.
Is the conductor tinned?
Yes. It's stranded tinned copper. The tin coating fights the corrosion that turns bare copper green, so your connections last out on the water.
How much wire is on the spool?
100 feet, all black. Pull off what each run needs and cut it to length.
Why stranded instead of solid wire?
Stranded wire flexes without fatiguing, so it handles the vibration and tight bends of a boat far better than solid wire. It's the standard for marine DC work.
