Butt Connecter ( Reducing)
A reducing butt connector joins two wires of different sizes in one insulated sleeve, with each end sized to its own wire. Auto electricians, appliance and harness makers, panel builders and dealers use it where a thick feed meets a thinner branch. This step down butt connector, also called a reducing splice connector, removes the need to double over or pack the smaller wire.

Reducing Splice Connector for Mixed Wire Sizes
Packing a thin wire into a large barrel gives a weak crimp that can pull out. A reducer wire connector has two barrels, each matched to its wire, so both sides crimp fully. Colours on each end show the size band, which makes picking easy. It is common on auto wiring, sensor leads and appliance repairs where a heavy lead meets a lighter one. See the product page for the size pairs available.
Crimp each side with a butt connector crimping tool, using the die that matches that end, and strip both wires with a wire stripper first. Every order comes direct from Ashwin Tools with 10-day returns. Auto electrical dealers can apply through our dealership programme.
