Ancor 22-18 Male Heatshrink Snap Plug - 100-Pack

The Ancor 22-18 Male Heatshrink Snap Plug 100-Pack delivers marine-grade electrical connections built to withstand saltwater, UV exposure, and harsh offshore conditions. These connectors combine cross-linked polyolefin tubing with heat-activated adhesive and nylon insulation to create impervious seals that resist salt water, oil, acids, and sunlight—essential features for any boat's electrical system.

Cross-linked polyolefin tubing is significantly stronger and more heat-resistant than standard PVC, eliminating the burn-through risk that compromises cheaper connectors in high-current applications. The integrated heat-activated adhesive lining provides both waterproof sealing and mechanical strain relief at the connection point—critical where vibration and flexing would otherwise degrade conventional crimped connections. UL Listed and CSA Recognized certification confirms these connectors meet North American electrical safety standards for marine environments.

Weekend anglers and serious offshore crews rely on these connectors for panel wiring, bilge pump circuits, navigation systems, and engine instrumentation where moisture intrusion and corrosion cause most mid-season failures. The 22-18 gauge range handles typical marine accessories from fish finders to trim tabs without oversizing. A 100-pack ensures spares for seasonal maintenance and emergency repairs miles from the dock.

Ancor supplies original equipment manufacturers and is preferred by professional marine electricians for deck-level reliability. These heatshrink snap plugs represent a pragmatic investment for any boater maintaining or upgrading 12V/24V systems in saltwater service, where connection failure can leave you dead in the water.
