nVent KING INNOVATION 20210 DryConn GTSR Direct Bury Waterproof Wire Connector with Yellow Nut, #18 to #10 AWG, 50V Low Voltage Irrigation Splice, UL Listed, 20210 (Formerly: King Innovation)

What It Is

The nVent KING INNOVATION 20210 DryConn GTSR is a direct-bury, waterproof wire connector for low-voltage (50V max) outdoor wiring, specifically designed for irrigation systems, landscape lighting, and lawn mower electrical splices (e.g., solenoid wires, battery connections). The yellow nut handles #18 to #10 AWG wire.

Fitment & Compatibility

• Wire gauge: Use only with solid or stranded copper wire between #18 AWG (small) and #10 AWG (thick). Check your mower’s wiring—most mower harnesses use #14 or #16 AWG, so this works for common splices.
• Voltage: Rated for 50V max, so it’s safe for 12V mower batteries, ignition coils, and solenoid valves, but not for 120V/240V AC circuits.
• Application: Best for outdoor splices (direct burial in soil or exposed to rain) on mowers with low-voltage electrical systems. Not for high-heat areas near engines or exhaust.
• Compatibility: No specific mower brand/model limits—works on any machine using #18–#10 wire. Confirm your wire is copper (not aluminum) for proper sealing.

Key Things to Know

• Waterproof seal: The gel inside self-seals around wires and stays flexible, preventing corrosion even when buried. No tape or heat shrink needed.
• Installation: Easy—strip 3/8” of insulation, insert wires fully into the connector, twist the nut until it clicks. The “click” confirms a secure, waterproof connection.
• Common gotcha: Don’t over-tighten—the nut can crack if forced past the click. Also, ensure wires are fully seated; partial insertion leaves gaps that let moisture in.
• Reusability: Not reusable. Once twisted, the gel locks in place and the connector must be cut off for rework.

Should You Buy It

Buy this if you need a fast, reliable waterproof splice for low-voltage mower wiring (e.g., repairing a corroded solenoid harness or extending battery cables) and want a no-tape solution that lasts years underground. Skip it for high-voltage or engine-bay connections.
