Wire Crimp Terminal Set

Unique-Bargains supplies ten tubular insulated ferrules in black for 4AWG 25mm2 conductors. Each terminal combines a tin-plated copper tube with a plastic sleeve that allows visual inspection of the crimp. The design prevents corrosion and provides a waterproof seal for harsh environments. Suitable for marine and automobile wiring tasks.

Marine And Auto Installers

These ferrules suit technicians who need sealed, inspectable connections on thick power cables. Builders working with smaller gauge wires or different terminal styles should look at other connector types. The pack contains only the ten crimp terminals themselves. No crimping tool, heat-shrink tubing or additional hardware is included in the package.

4AWG 25mm2 Wire Gauge Fit

The copper tube measures 7.5 x 8 x 16mm inner diameter, outer diameter and length to match 4AWG 25mm2 cable. Correct wire gauge alignment is the single specification that decides whether this terminal fits the job. Verify the conductor size before ordering to ensure a proper crimp and seal.

Questions about this item

What crimping tool accepts the 7.5 mm inner diameter copper tube?

A ratchet crimper with a 25 mm² / 4 AWG die set will fully compress the 7.5 mm inner diameter tube without damaging the black insulation sleeve.

Will the 16 mm barrel length fit inside my existing terminal block?

The 16 mm copper barrel matches standard 25 mm² block depths; measure your block cavity to confirm it accepts a 16 mm insertion length.

How can I verify each crimp is watertight after assembly?

The transparent insulation lets you see the wire fully seated to the barrel end; tug gently and confirm no conductor strands are visible past the crimp line.
