Ferrule crimp connectors have grown in popularity over the years, especially when fitting aftermarket electronics to vehicles.

Wire ferrules, when used with the correct crimping tool, replace the need for �tinning� the wire ends with solder. The ferrules are crimped on to the end of a bare wire to improve support of the wire and the connection quality. The 4-tooth crimping tool supplied ensures a tidy and very strong crimp. Quicker and easier than tinning the wire end. The simplest and safest way for our customers to pay for items is through PayPal.
