Heat sealable and heat shrinkable sleeve

HEAT-SEALABLE AND HEAT-SHRINKABLE SLEEVE

The connections between wires must guarantee good current flow, but also avoid energy leakage. Heat-sealable and heat-shrinkable sleeves fulfill this function. These are connecting elements for your cables and other electrical wires.

What is a heat-sealable and heat-shrinkable sleeve

The heat-weldable and heat-shrinkable sleeve is a sleeve that differs from a normal sleeve due to its material and its components. If traditional sleeves are made of metal and crimped, heat-weldable and heat-shrinkable sleeves come in cylindrical form made from special plastic elements. However, they are made up of a metallic component to improve the conductivity of electricity (new generation sleeves). This component is generally a tin ring, there are also two other rings guaranteeing the tightness of the connection. To fix the wires together, you need to heat the sleeve. Heating the sheaths ensures that the wires are held in place and the electricity passes through correctly.

Operation of the heat-sealable and heat-shrinkable sleeve

The operation of the heat-sealable and heat-shrinkable sleeve is quite simple. However, you must equip yourself with special tools. Pliers to strip your wires and a device to heat the sheath like a heat gun. You will first need to strip your wires to the correct length. Once the wires are stripped, you can twist them for more grip. Insert the wires to be connected inside the sleeve then heat the plastic sheath. The sheath will then retract on itself, the middle tin ring will also melt and completely weld the wires for better conduction of electricity. Pull on the wire with the sleeve cooled to ensure the wires are holding properly. Please note, this action is irreversible; it will be difficult to disconnect the sleeve except by cutting it.

The different types of heat-weldable and heat-shrinkable sleeves available

We have various heat-weldable and heat-shrinkable sleeves on site ready for delivery.They are of various sizes and dimensions intended for all types of wires and cables. There are models from 1 mm² to 20 mm² and models of various lengths. Our stock concerns transparent sleeves with ring, and single-color sleeves (black, red, yellow) so that you can find your way through your connections. We sell our sleeves individually, in batches, or in kits. The sleeves offered are certified and are from recognized brands. They respect a set of standards, particularly in terms of tension, but also in terms of resistance to high temperatures. Choosing our sleeves means guaranteeing an electrical connection for life.

Role of heat-weldable and heat-shrinkable sleeves

This type of part has a dual role, allowing you to connect your wires, but also to seal your wires. The connection of your wires is thus improved thanks to the tin ring which is an excellent conductor. The sealing rings at each end prevent any moisture or product from the vehicle (acid, grease, etc.) from filtering through. The sheath system guarantees extreme fixation of the two wires. You will no longer be able to disconnect your wires through the sleeve, you will have to cut it to another length. Use this type of fitting only for permanent connections.
