This is a rapid process and typically takes about 5 seconds using a heat gun. Using a heat source, eg: heat gun, heat the heat shrink connector. These electrical connectors can only be used once. If the connection is loose, remove wires, dispose of the used connector and repeat the process using a new butt connector. To check connection integrity gently pull the wires on both sides of the butt connector to ensure the connection is not loose and has been successfuly crimped. Repeat the above steps 3 through to step 7 for the wire to be connected on the other side of the butt connector. Repeat Process for Wire on Other Side of Butt Connector To effect a secure crimp a considerable anount of force may be required. Securely hold the wire in the appropriate crimp position and squeeze firmly on the crimper handles. This colour coded system provides a fast and easy way to determine the correct indentation to be used. Using an appropriate wire crimping tool match the colour of the butt connector with the colour coded size gauges in the crimping tool. If the exposed area is too long cut a little off the end using the stripping or crimping tool. At this point it is easily determined if the exposed wire segment is too long for the butt connector about to be used. Insert the newly stripped wire end halfway into the connector. It is now time to select an appropriate butt connector for this wire size - Yellow/ Blue/ Red. We previously determined the correct wire size and recorded it. You may find that wrapping the wire around your other hand provides better grip to assist this process.Īt this point the internal multiple wire strands that are now exposed should be tidied together by twisting. The wire may present some resistance to this movement so it may take some effort. Slide it towards the outside of the wire to remove the plastic casing. Rotate the tool about the wire to ensure it has cut cleanly all the way around the insulation. Rotate the Stripping Tool and Slide Off the Wire Insulation Record the number used on the stripping tool for later. Close and squeeze the handle so that the insulation is cut into. Then place the stripping tool one size smaller than determined in the previous step onto the wire. Now that the outside size of the wire has been determined move in about 3/8 inch from the wire end to be connected. You are looking for a hole size that fits tightly around the outside of the wire so that you struggle to move the wire yet it does not cut into the insulation. Place the wire inside the appropriate hole and close the gap. Move progressively towards the lowest hole until you determine the correct gauge. Beginning with the largest hole check the size of the wire. Grab a wire stripping tool and hold the wire in one hand. How to Connect Electrical Wires using a Heat Shrink Butt Connector:Ĭheck that there is no electrical current running through it. We offer a range of adhesive lined heat shrink butt connectors in different sizes - which are colour coded yellow, blue and red. These red butt terminals are used to terminate wires in the range of 0.5 - 1.5 mm 2 safely or to create safe and reliable connections between two wires. There are many different types of electrical crimp connectors to choose from. We stock over 5,000+ products in our warehouse and our entire range is available at highly competitive trade prices.Īdhesive Lined Heat Shrink Electrical Butt Connectors:Ī red butt heat shrink connector is a type of precision crimp connector commonly used in the profesional automotive garage. In addition to heat shrink electrical butt connectors we supply a wide range of electrical terminals, crimping tools and automotive electrical accessories. How to Install a Heat Shrink Butt Connector: To implement a secure and reliable connection simply insert the wires into the butt terminal, perform a crimping action and then heat shrink for a complete environmental seal. They provide rapid shrink times and maximum abrasion resistance. These red butt connectors are constructed to provide maximum visual clarity for wire inspection purposes. Red Heat Shrink Electrical Butt Terminals: The adhesive lined heat shrink sleeves provide a tightly sealed, safe and secure electrical connection when installed. They provide a quick and easy method to achieve reliable, secure and environmentally sealed electrical connections. The heat shrink ratio for these terminals is a standard 3:1. The insulating casing is engineered from high quality nylon polyolefin and is adhesive lined for secure relaible sealing. These professional grade automotive red heat shrink butt connectors are constructed from premium tin plated copper.
