Tinned copper barrel, nylon insulation, and serrations that grip the wire so your splice holds up under vibration and salt air. Five to a pack. The everyday connector for joining two runs end to end on a 12 or 24 volt DC system.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen you're splicing two wires end to end on a boat, you want a connection that holds and doesn't corrode six months later. The Ancor 230120 is a single crimp butt connector sized for 12-10 gauge wire, and it's built the way marine wiring should be. Tinned copper barrel, nylon insulation, and serrations inside the barrel that bite the wire so it won't pull back out. You get five of them in this pack.\u003c\/p\u003e\n\u003cp\u003eHere's what single crimp means in practice. Each end of the connector takes one crimp to lock onto the wire. Strip your wire, slide it into the barrel until it bottoms out, and crimp. Do the same on the other side and you've joined two runs into one continuous conductor. It's the everyday splice you reach for when you're extending a bilge pump lead, repairing a chafed run behind the dash, or tying in a new accessory circuit.\u003c\/p\u003e\n\u003cp\u003eThe barrel is the part that matters most out here. Ancor uses a seamless tinned copper barrel, so there's no split seam to open up under vibration, and the tin plating fights the corrosion that eats bare copper alive in salt air. Serrations stamped inside the barrel grip the wire strands, which keeps the splice from backing out when the boat's pounding through chop. Tinned copper also gives you low electrical resistance, so you're not dropping voltage across the joint.\u003c\/p\u003e\n\u003cp\u003eThe insulation is nylon, and that's a deliberate choice. Nylon is tougher than vinyl. It won't split or crack when you crimp it, and it stands up to abrasion and heat better than a thin vinyl sleeve. The 12-10 gauge size is color coded yellow, so anyone working the circuit later can read the gauge at a glance. Yellow is the standard code for 12-10 gauge terminals, so it matches the rest of a properly color coded harness.\u003c\/p\u003e\n\u003cp\u003eUse these anywhere you're joining 12 or 10 gauge wire on a 12 volt or 24 volt DC system. Bilge pumps, livewell pumps, nav lights, stereo power leads, accessory circuits, trailer wiring. If you rig boats for a living you probably go through these by the hundred. For a weekend repair, a five pack covers most jobs with a couple to spare.\u003c\/p\u003e\n\u003cp\u003eOne honest note on water. The nylon insulation resists moisture and the tinned barrel resists corrosion, so these hold up well in the damp, splashy reality of a boat. But nylon butt connectors aren't adhesive lined heat shrink. They don't seal the splice against standing water. If you're making a connection that sits underwater or somewhere that floods, like deep in a bilge, step up to an adhesive lined heat shrink butt connector that melts a watertight seal around the wire. For everything above the waterline and out of standing water, these do the job and do it cleanly.\u003c\/p\u003e\n\u003cp\u003eCrimp them with a proper ratcheting crimper sized for insulated terminals. A good crimp is the whole game with butt connectors. Too loose and the wire works free, too crushed and you nick the strands. A ratcheting tool takes the guesswork out and gives you the same clean crimp every time. Give each side a gentle tug after you crimp, and if it holds, you're good to go.\u003c\/p\u003e\n\u003cp\u003eAncor has been building marine grade wire and connectors for decades, and the whole line is designed around the reality that a boat's electrical system lives in a harsh, wet, vibrating environment that destroys gear built for dry land. These butt connectors carry that same marine grade pedigree. The tinned copper, the seamless barrel, the nylon insulation, they're all there because standard connectors fail early on the water. It's the difference between a repair you make once and one you're back fixing next season.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSingle crimp butt connector for 12-10 AWG wire, joins two runs end to end\u003c\/li\u003e\n  \u003cli\u003eSeamless tinned copper barrel resists corrosion in salt air and keeps electrical resistance low\u003c\/li\u003e\n  \u003cli\u003eInternal barrel serrations grip the wire strands to stop pull-out under vibration\u003c\/li\u003e\n  \u003cli\u003eNylon insulation won't split or crack when crimped, tougher than vinyl\u003c\/li\u003e\n  \u003cli\u003e12-10 gauge size color coded yellow for easy gauge identification\u003c\/li\u003e\n  \u003cli\u003eMarine grade construction built for 12V and 24V DC boat wiring\u003c\/li\u003e\n  \u003cli\u003eHandles bilge pumps, nav lights, livewell pumps, stereo leads, and accessory circuits\u003c\/li\u003e\n  \u003cli\u003ePack of 5 connectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Ancor reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat wire gauge do these butt connectors fit?\u003c\/summary\u003e\n    \u003cp\u003eThey're sized for 12-10 AWG wire.
