Fully insulated, waterproof female quick disconnect for 16-14 AWG stranded copper wire. The heat shrink covers the whole 0.250" receptacle as well as the crimp, so no bare metal is exposed once it is plugged onto a tab. The adhesive-lined heat shrink sleeve melts and seals around the wire insulation when heated, blocking moisture, salt and road spray from reaching the crimp. Made in USA.
Use it for: general-purpose automotive, trailer, marine and equipment wiring — lighting, horns, fans and accessory circuits on boats, trailers, truck and off-road wiring, outdoor lighting and anywhere a connection sees water, washdown or vibration, especially where the terminal sits close to other connections or grounded metal.
Choose something else if: you are working dry and indoors — a nylon fully insulated disconnect crimps faster and needs no heat gun. Install with a ratcheting crimper, then heat until the adhesive shows at the ends.

• Marine Electrical Systems - Connect windlass motors, bilge pumps, navigation lights, and electronics in boats where saltwater exposure requires waterproof connections that can still be disconnected for maintenance or winter storage.
• Trailer & RV Exterior Wiring - Wire running lights, brake lights, and exterior accessories exposed to road spray, weather, and moisture where waterproof quick-disconnect capability allows easy trailer unhitching or component replacement.
• Outdoor Power Equipment - Connect charging systems, electric start motors, and accessories on lawn tractors, generators, and outdoor machinery where weather exposure and seasonal storage require waterproof modular connections.
• Underground Irrigation & Lighting - Wire valve solenoids, pump controls, and landscape lighting in buried applications where waterproof connections prevent corrosion while allowing access for repairs or seasonal adjustments.
