Crimp Terminals for Reliable Electrical Connections

Quick Answer

Crimp terminals join wires securely without soldering, using a compression fit between terminal and wire. We stock them in pure copper or brass, both tin coated, in insulated and non-insulated types, sold in packs of 50.

Why Crimping Instead of Soldering

Crimping produces a joint by compressing a terminal around a stripped wire end rather than melting solder into the connection. Done correctly, it's fast, repeatable, and doesn't need much training to get a reliable result, which is a big part of why it's the standard method in automotive and industrial wiring rather than soldering every joint by hand.

Materials

Our lugs are pure copper, tin coated. Crimp terminals are either pure copper or brass, also tin coated. The tin coating helps resist corrosion and keeps the connection point conductive over the life of the wiring, rather than degrading at the joint over time.

Types We Stock

Non-insulated terminals for applications where the connection will be covered or protected separately, and pre-insulated terminals with a PVC insulated barrel for a self-contained, protected connection straight out of the pack.

Pairing with Heat Shrink

For extra protection against moisture and abrasion, crimp terminals are often finished with heat shrink tubing over the joint, adding sealing on top of the crimp itself. This combination is common wherever a connection needs to hold up in an outdoor or engine bay environment rather than a dry indoor panel.

Getting a Reliable Crimp

The connection quality depends on matching terminal size to wire gauge and using a proper crimping tool rather than pliers or a makeshift substitute. A correctly sized crimp on the right tool gives a consistent, repeatable result every time, which is what makes crimping reliable enough to use without soldering as a backup.

Common Questions

What are crimp terminals used for?

Joining wires securely without soldering, common in automotive, industrial and general electrical work.

What materials are your crimp terminals made from?

Pure copper or brass, both tin coated, with lugs made from pure copper, tin coated.

What's the difference between insulated and non-insulated terminals?

Insulated terminals come with a PVC barrel for built-in protection. Non-insulated terminals suit applications where the connection is protected separately, such as under heat shrink.

Can crimp terminals be used with heat shrink tubing?

Yes, heat shrink is commonly added over a crimped joint for extra moisture and abrasion protection.

What pack size do these come in?

Sold in packs of 50.
