The VALUE COLLECTION BD-18557 is an IDC tap quick splice connector designed for fast, tool-free wire tapping on 18 to 14 AWG conductors. IDC (insulation displacement contact) termination allows a technician to splice into an existing wire run without stripping insulation. The connector accepts two wire entries and is rated for a maximum operating temperature of 194 degrees F. The black housing provides basic identification at a glance. These connectors are commonly used by electricians, HVAC technicians, and low-voltage installers who need a reliable inline tap without soldering or wire nuts.
This connector is suited for residential and light commercial applications where a branch connection must be made to an existing wire run. Typical use cases include tapping into thermostat wiring, sensor circuits, lighting control runs, and other low-voltage or secondary wiring in HVAC, electrical, and building automation installations. Each package contains 25 connectors, making it practical for service trucks and panel shops that go through splice connectors regularly. The IDC termination method keeps installation time low on repetitive wiring tasks.
Designed as an OEM-style replacement and general-use tap splice connector for 18 to 14 AWG wire applications in low-voltage electrical, HVAC control, and building automation wiring systems.
Installation is performed by electricians or HVAC technicians following applicable NEC guidelines for the circuit type. De-energize the circuit before inserting conductors into the connector. Seat the wire fully before closing the IDC cap to ensure the displacement contact pierces the insulation cleanly. Do not exceed the rated wire size range, as undersized or oversized conductors will result in an unreliable connection.
