3M 7000058872 Female T-tap Disconnect 22-18 Awg

Product Description

The 3M 7000058872 is a nylon-insulated, self-stripping female quick slide disconnect designed for mid-span wire tapping on 22-18 AWG conductors. The T-tap design allows an electrician or installer to establish an electrical connection to an existing wire without cutting or stripping the wire. The connector mates with a 0.250 inch male tab for a reusable quick-connect termination. Maximum insulation outer diameter is 0.150 inches, and the connector is rated for operating temperatures up to 221 degrees F (105 degrees C). Suitable for low-voltage wiring work in residential and light commercial electrical, HVAC controls, and automotive-style harness applications.

This T-tap disconnect is used wherever a branch connection must be made to a live wire run without interrupting the existing conductor. Typical applications include adding a circuit branch to a control wire in an HVAC system, tapping into a low-voltage wire for an accessory circuit, or any scenario where mid-span splicing without wire prep is required. The mated male tab size is 0.250 inches, compatible with standard quick-connect male tabs such as the MNG10-250 DMI. The recommended application tool is the E-9BM Crimping Tool.

Key Features

• Self-stripping T-tap design — no wire cutting or stripping required at the tap point
• Accepts 22-18 AWG conductors for a wide range of light-gauge wiring applications
• Mates with 0.250 inch male tab for a reusable quick-connect termination
• Nylon insulation rated to 221 degrees F (105 degrees C) operating temperature
• Maximum insulation outer diameter of 0.150 inches
• Compatible with E-9BM Crimping Tool for consistent, tooled terminations

Compatibility

Designed to mate with 0.250 inch male tab connectors, including the MNG10-250 DMI. Recommended application tool is the 3M E-9BM Crimping Tool. Suitable for 22-18 AWG wire in low-voltage control and signal wiring applications.

Installation Notes

Installation is typically performed by licensed electricians or HVAC technicians working on low-voltage control wiring. De-energize the circuit before making any connections and verify the wire gauge falls within the 22-18 AWG range before applying the connector. Use the E-9BM Crimping Tool or an equivalent tool approved for self-stripping T-tap connectors to ensure a secure, gas-tight termination. Work performed on electrical systems must conform to applicable NEC requirements and any local code amendments.
