Installation Procedure

Funnel Barrel Feature provides an excellent electrical

and mechanical connection.

• Funnel design guides wire into position.

tubing effectively resists abrasion, scoring, cut-through,

and the effects of long term aging.

Versatile and Easy to Use – 3M heat shrink terminals,

splices and disconnects are available in wire sizes 22–10

AWG, and can be installed easily with a recommended tool

and heat source. The connectors are color-coded for wire

range identification, and the transparent tubing allows for

visual inspection.

• No wire strand hang-up as the wire is inserted, giving

a fast, positive installation.

• Wire is in place, ready for crimping.

For maximum crimping performance, barrel of connector

must be properly indexed in the crimp tool station.

Correct crimping is important

to assure a strong connection

High Temperature Terminals

and Connectors

3M high temperature terminals and connectors are

constructed of steel with a nickel plating. Their temperature

rating for continuous use at 900°F (482°C) makes them

perfect for use in ovens, motors, light fixtures and other

applications where other connectors would corrode or melt.

There is no applicable UL or CSA standard for high

temperature steel parts.

Application Procedure for

Heat Shrink Products:

1. Strip wires to appropriate

length as indicated on package

label.

2. Insert wire into terminal

and crimp with correct

station of a recommended tool.

3. Apply heat with a

recommended heat source.
