Female Disconnect Terminals

These 3M Scotch female disconnect terminals provide insulated wire connections for automotive and industrial electrical work. The red vinyl insulation identifies the wire gauge range and protects the crimp joint. A pack of 100 pieces supports volume wiring tasks such as vehicle harness repair or panel building.

Vinyl Insulation and Certifications

The vinyl sleeve resists abrasion and common automotive fluids while keeping the crimp covered. CSA certification, UL listing and RoHS compliance confirm the terminals meet recognised safety and environmental standards for permanent installations. The insulation colour also speeds visual identification during assembly or troubleshooting.

18 to 250 Series Compatibility

These terminals accept wire sizes in the 18 to 250 range and mate with matching male tabs of the same series. Buyers using a different tab width or wire gauge outside this range will need a different terminal style to achieve a secure connection.

Questions about this item

Do the red vinyl insulators on these female disconnects become brittle and need replacement after years of engine-bay heat?

The vinyl insulation is rated for continuous operating temperatures typical of automotive wiring; it does not have a published replacement interval, so inspect during routine harness checks.

What current level will cause the 0.87 in copper barrel to hit its thermal limit first during a long drive?

The 18–250 DFX series is UL listed for 250 V applications; sustained current should stay within the wire gauge rating to avoid overheating the barrel.

How much heat does a full 100-piece harness of these connectors add to a closed fuse box after hours of use?

Each vinyl-insulated disconnect adds negligible resistive heat; total rise inside a sealed box depends on the combined load of all circuits, not the connectors alone.
