What You'll Learn
Crimp sleeves are used for electrical wire connections
Crimp sleeves are used to connect two wires or to form a loop at the end of a single wire. They are commonly used for electrical wire connections, and they come in a variety of geometries, sizes, and materials. For example, they can be cylindrical, figure-8, or oval-shaped, and are often made from materials such as aluminium, stainless steel, or copper.
Aluminium crimp sleeves, for instance, are a popular alternative to stainless steel due to their cost-effectiveness, lightweight nature, and resistance to oxidation in humid or saltwater conditions. The atomic structure of aluminium and copper also makes these metals more malleable, allowing them to be pressed into shape more easily than harder metals like steel.
Crimp sleeves designed for smaller cables, such as 0.006" cables, typically use a small sectioned piece of stainless steel or brass tubing that is swaged or pressed to the cable. In some cases, a simple household tool like a pair of pliers can be used to attach the fitting to the cable. However, for larger cables or more complex assemblies, an industrial press or specialised tool may be required to ensure a secure connection.
When using crimp sleeves, it is important to select the correct size and type of sleeve for the specific wire gauge and application. For example, one source mentions that crimp sleeves for 8-10 gauge smooth wire are available, while another source discusses the use of crimp sleeves for 12.5 gauge smooth wire, requiring two crimps per splice. Additionally, it is worth noting that crimp sleeves are commonly used for temporary electrical connections, especially in applications like electric fencing.

They are ideal for creating permanent electrical connections
Crimp sleeves are commonly used wire rope and mechanical cable fittings. They are also known as loop sleeves. Crimp sleeves are popular as they are designed to serve two fundamental cable assembly functions: forming a loop at one or both ends of a length of cable and/or attaching two separate pieces of cable together.
Crimp sleeves are available in different geometries, sizes, and materials. They can be cylindrical, figure-8, or ovular. The most common materials used for crimp sleeves include stainless steel, brass, copper, and aluminium. Aluminium crimp sleeves are a good alternative to stainless steel as they are cost-effective, lightweight, and do not oxidize when introduced to humidity or saltwater conditions.
Crimp sleeves are typically applied to cables using a hand tool or an industrial press. For smaller cables, such as .006” cable, a small, sectioned piece of stainless steel or brass tubing is swaged or pressed to the cable. In the case of miniature brass crimp sleeves, one can attach the fitting to the cable using a household pair of pliers. However, it is important to note that using one's hand to press the crimp sleeve to the cable assembly can introduce variability to the forces being applied to the fitting. An industrial press would provide more reliable and consistent results.
The open tap crimp sleeve is ideal for making permanent electrical connections on 12½ and 14 gauge wire. They are designed to splice any wire product available today and are perfect for creating strong and long-lasting electrical connections.

Crimp sleeves are used in electric fences
To install crimp sleeves, a crimping tool is used to squeeze or swage the sleeve onto the wire. It is important to start at one end and work along the length of the sleeve, overlapping the previous crimp. Compressing the sleeve 4-5 times ensures a solid joint, and it is crucial to ensure that the compressed sleeve remains cylindrical without splitting. When using multiple sleeves per splice, leaving a small gap of at least 1/4" between sleeves is recommended to allow for proper expansion.
Crimp sleeves are commonly used in livestock electric fences, where they provide high-tensile wire connections that are more durable than hand-tied fence knots. They are also useful for trellis fencing. The Strainrite brand, for example, offers crimp sleeves that are designed to add tension or splice strands of high-tensile fencing wire. These sleeves are made in New Zealand and have received positive reviews from customers.
In addition to crimp sleeves, other connectors such as quick-splices, splicers, gripples, and wrap connectors are also used in electric fencing. Quick-splices, for instance, simplify fencing projects by allowing wires to be joined without the need for special tools or technical expertise. However, crimp sleeves offer a versatile solution for creating strong wire connections in electric fences.

They are available in different materials, geometries, and sizes
High-pressure crimp sleeves for electrical wires are available in a variety of materials, geometries, and sizes. The most common materials used for these crimp sleeves are stainless steel, aluminum, brass, and zinc-plated copper. Aluminum crimp sleeves, for instance, are a popular alternative to stainless steel due to their cost-effectiveness, lightweight, and resistance to oxidation in humid or saltwater conditions. They are available in ovular and figure-8 geometries, which can be used interchangeably in certain scenarios.
Zinc-plated copper crimp sleeves, on the other hand, offer similar resistance to humidity and harsh environments. The atomic structure of aluminum and copper makes them more malleable, allowing them to be shaped more easily compared to harder metals. Crimp sleeves can also be made from aluminum alloy (6063-T6), which provides enhanced conductivity, mechanical strength, time and cost efficiency, and consistency.
In terms of geometry, crimp sleeves can be cylindrical, figure-8, or ovular. The ovular shape is created by pressing the fitting into an oval, allowing a single cable to pass through twice or joining two cables. The figure-8 design, meanwhile, ensures more points of contact for the crimp fitting to make with the cable, resulting in a more secure connection.
Crimp sleeves also come in various sizes to accommodate different wire gauges and applications. For instance, mechanical cable larger than 3/8" is considered wire rope, while cable smaller than this is typically referred to as mechanical cable. It's important to select the correct size and material to avoid system failures and ensure the designated load is held securely.

Crimping tools are used to cut, crimp, and strip wires
Crimping tools are used to create secure and reliable connections between wires. They are an essential part of any electrician's toolkit and are commonly used in electronics, telecommunications, and automotive wiring applications. Crimping tools are designed to form a strong connection that is properly sealed from gas or moisture, preventing shortages or faulty electrical connections.
To use a crimping tool effectively, it is important to follow the correct process. First, the insulation must be stripped from the wire, exposing the desired length of the bare wire without damaging the wire conductor. Then, the bare wire end is inserted into the crimp terminal barrel until it reaches the end. The crimp terminal, along with the wire end, is then placed into the crimping tool, ensuring that the terminal is correctly positioned. Next, pressure is applied to the crimping tool handles to compress the crimping die and create a secure connection. Finally, the pressure is released, and the crimp connection is inspected for any signs of damage.
It is crucial to select the appropriate crimping tool and terminal for the specific wire size and type, as well as the application. Common mistakes to avoid include using the wrong size terminal or wire gauge, insufficiently stripping the wire insulation, and over-crimping or under-crimping the terminal. It is also important to ensure compatibility between the crimping tool and the connectors being used, as different connectors may require specific crimping dies or jaws.
Some crimping tools are designed with a ratchet feature, which helps control the crimp and removes human error, resulting in a consistent and reliable connection every time. These tools are especially useful when working with thin cables, where there is a smaller margin for error. Additionally, certain crimping tools come with colour-coded nests or wire gauges imprinted on them to help choose the correct nest for the terminal.
While crimping tools are primarily used for crimping wires, some tools also have the capability to cut and strip wires. For example, the 2-Slot Hayes Crimping Tool is designed to cut, crimp, and strip common fence wires, and some crimping tools may have a feature for scoring insulation to remove it.
