3M 7000133378 Ring Heat Shrink Connector 25 Per Bottle

Product Description

The 3M 7000133378 is a ring-style heat shrink wire connector sold in bottles of 25. This connector combines a copper ring terminal with a polyolefin heat shrink sleeve, creating a moisture-resistant, insulated termination point once heat is applied. Electrical technicians and low-voltage installers use these connectors to terminate wire ends at screw terminals, lugs, and binding posts in residential, commercial, and light industrial wiring applications. The heat shrink sleeve bonds to the wire jacket as it shrinks, reducing the risk of pull-out and protecting the connection from corrosion and vibration-related failure.

Ring heat shrink connectors like the 7000133378 are commonly used in HVAC control wiring, panel work, automotive electrical, marine applications, and general electrical maintenance. They are suited for any environment where a secure, insulated ring termination is needed and where exposed crimp connections would be vulnerable to moisture or mechanical stress. Sold in a 25-count bottle, this format supports service truck stocking and job-site use by electricians, HVAC technicians, and marine service professionals.

Key Features

• Ring terminal style for screw and lug terminations
• Heat shrink sleeve provides insulation and moisture resistance after activation
• 25 connectors per bottle for convenient service stocking
• Polyolefin shrink material bonds to wire jacket when heated
• Reduces corrosion and vibration-related connection failure

Compatibility

Designed as an OEM-style ring heat shrink connector suitable for general electrical, HVAC control wiring, and low-voltage termination applications where a ring terminal with heat shrink insulation is required.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians. Strip wire to the appropriate length, insert into the connector barrel, and crimp using a ratcheting or standard crimp tool before applying heat to shrink the sleeve. Always de-energize the circuit before making any terminations. Follow applicable NEC requirements for wire gauge, connector rating, and enclosure type.
