PetsTEK 20 Pack Direct Bury Waterproof Wire Splice Kit, Wire Nut Electrical Connectors for Wire Break Repair, Compatible with PetSafe, SportDog, Dogtra In-Ground Dog Fence Systems, Made in USA

What It Is

This is a 20-pack of direct-bury waterproof wire splice connectors designed for repairing broken or cut wires in in-ground pet containment fence systems. It’s not for lawn mowers—it’s for the buried wire loops used with brands like PetSafe, SportDog, and Dogtra.

Fitment & Compatibility

Before buying, confirm your fence system uses a single-strand 20–22 AWG solid copper wire (most do). These connectors work with standard underground fence wire, not braided or multi-strand cables. No deck size or mower model applies—this is purely for the boundary wire, not for mower electrical systems. If your fence wire is thicker than 18 AWG or is shielded/coaxial, these splices won’t fit.

Key Things to Know

• Waterproof rating: Each connector uses a silicone gel sealant that holds up underground without additional tape or heat shrink—tested for direct burial.
• Installation: No stripping or crimping required. Insert both wire ends, twist the cap until it clicks, and the internal gel seals the connection. Takes about 30 seconds per splice.
• Common gotcha: The connector works best with clean, dry wire ends. Dirt or moisture on the wire can reduce the seal’s effectiveness—wipe the wire with a dry cloth before inserting.
• Made in USA: All 20 pieces are manufactured domestically, which may matter for quality consistency.

Should You Buy It

If you have a broken underground fence wire and want a fast, no-tool repair that’s rated for direct burial, this kit is a solid choice. It’s overkill if you only need one splice, but the 20-pack price per connector is reasonable for multiple repairs or sharing with a neighbor. Skip it if your fence uses stranded or shielded wire—these are designed for solid 20–22 AWG only.
