Adhesive-filled heat shrink wire connectors designed for landscape and architectural lighting splices. Each medium connector provides a waterproof, direct-burial seal and two levels of strain relief to preserve connections in wet or high-stress environments.

  • Waterproof adhesive-lined heat-shrink tube creates a moisture-tight seal to prevent shorts and corrosion.
  • Tin-coated copper butt splice ensures solid metal-to-metal contact for reliable electrical continuity.
  • Medium size fits two 10 AWG (6.0 mm2) or three 12 AWG (4.0 mm2) conductors—ideal for splitting home runs.
  • Two levels of strain relief from crimping and heat-shrink tubing reduce stress on leads and fixtures.
  • Sold in a pack of 20; compatible with the LightingShrink ratcheting crimper tool for consistent crimps.

These connectors are purpose-built for installers who need fast, secure, and weatherproof splices for low-voltage lighting. Use proper crimping tools and a heat source per manufacturer instructions to achieve a permanent, watertight seal.
