What are ring terminals?
Ring terminals are used to connect wires to a connection point by fitting the open face of the terminal over a stud. These wire connectors create a solid connection as the ring that is fitted over the stud cannot come loose or fall off. These types of crimp connectors are built for long-term use. This removes the possibility of the ring terminal disconnecting. They are widely known for the semi-permanent connections that they create. To make ring terminals even better, they can easily be used with two or more wires depending on the application. Ring terminals are the most secure type of crimp connectors available and are commonly chosen for their durability, ease of use, and longevity in tough conditions.

How do you use ring terminals?
Installing ring terminals is easier than you may think. The first thing you need is the proper tool. Depending on the types of crimp connectors you are using, you will need specific tools. We'll be using the VTTR50 as it can crimp 22 to 8 gauge terminals. Once your wires are properly stripped and prepared simply slide the wire into the terminal body making sure the insulation butts up to the barrel of the ring terminal. Make sure you insert the terminal into the proper crimp nest. Identification is made easy by the colored dots which should match the insulation on the ring terminal. Now, simply close the tool with the terminal barrel centered. One completed cycle of the tool is all it takes to complete the crimp. When inspecting the crimp, look for clean indentations and ensure that the terminal is not damaged or bent. The next step is to activate the heat shrink using the proper tool. All that's left is the tug test. With a gentle pull, you'll be able to tell if the crimp will hold or not.
Where are ring terminals implemented?
Ring terminals are implemented in many systems
Ring terminals are implemented by boat builders, repair shops, and everyday boaters on a daily basis. They are some of the most popular terminals in use today. People use our ring terminals to not only install or repair connections, but they use them in replacement parts as well. They are known for their ease of installation and durability. When used with the proper tools, our ring terminals can be used to create high quality electrical connections. Now that we have covered the basics, let us look at how they are advantageous.
Why use ring terminals, how are they advantageous?
Ring terminals are advantageous as they create a semi-permanent connection point that can be accessed and adjusted if needed. They are often used in applications where the connection point, materials used, or equipment connected may be subject to change. Their versatility allows them to perform in a way other terminals cannot handle. You will commonly find them used on bus bars and other pieces of equipment where studs are present. Ring terminals offer benefits that you cannot get with other types of terminals such as fork terminals.
How do I know which stud size is the right one for my project?
The stud size refers to the size, or diameter, of the stud you will be attaching the ring terminal to. We offer seven different stud size options: #6, #8, #10, ¼”, 5/16”, 3/8” and , ½”. The first three options: #6, #8, and #10 refers to sizes smaller than ¼”. The easiest way to know exactly what stud size you are working with is to measure the shank, or shaft-like section of the stud. You can use a caliper if you have one, otherwise a ruler will work just fine. So, if the shank of the stud has a diameter of 3/8” then you need a 3/8” ring terminal.
What is the difference between ring terminals and fork terminals?
Ring terminals and fork terminals carry several distinct differences and are best suited for applications where those differences offer an advantage. Ring terminals carry an open face that fits over a stud or screw and creates a lasting connection point that will not come loose or pull free. Fork terminals are fully open on one side and allow the operator to add them to a stud or screw without having to fully remove any equipment or connectors. Ring terminals offer a stronger connection point whereas fork terminals may be easier to install in certain situations.
What tools should I use with ring terminals?
Ring terminals can only be used with the correct type of crimper in order to get the strongest connection possible. Using the incorrect tool will lead to unsatisfactory results and likely compromise your electrical connections. Crimp connectors are the most secure of electrical connectors to use. The most versatile crimper we offer is the VTTR50 which can crimp any ring terminals available other than non-insulated, or bare terminals. If you need to crimp non-insulated or bare terminals, use our VT3120CT which can work with all of the ring terminals available. Regardless of the electrical wire connectors you are using, these tools are built with longevity and repeatability in mind. These are the same tools that we actually use on our own internal production lines. This shows just how trustworthy these tools actually are. Think about it, would we use tools that we didn't test and trust? Not likely.
What types of ring terminals are available?
Pacer offers ring terminals in a range of gauge sizes including 22-18 AWG, 16-14 AWG, 12-10 AWG, and 8 AWG. Additionally, we offer them in heat shrink, nylon, vinyl, and non-insulated. We offer so many gauge sizes and insulation types so that you can find exactly what you need to finish your project. By offering you the most solutions possible, we hope to show you that we are the experts and only offer the best. One question that we receive frequently is in relation to the insulation type.
Does the insulation type really matter?
The insulation on a ring terminal plays a major role in the quality and longevity of the connection. Heat shrink ring terminals offer the longest-lasting protection and create an environmental seal. They accomplish this with the epoxy that lines the interior of the terminal. As you activate the heat shrink, that epoxy melts and creates a durable, moisture-proof seal. Nylon insulation ring terminals are the next step down. They offer the same durable connection, just without the epoxy-lined seal. Vinyl insulation is more rigid and offers slightly less protection but is more cost-effective. The non-insulated, or bare terminals are the most affordable option but that comes at the cost of added protections. So, you can see just how important selecting the right insulation for needs can be.
Does Pacer offer ring terminals that create environmentally sealed connections?
Yes, Pacer does offer ring terminals that can be used to create environmentally sealed connections. It is important to note that not all Pacer ring terminals create this type of connection. In order to get the highest quality seal possible, you have to select the correct type of ring terminal. Our epoxy lined heat shrink ring terminals offers the highest level of protection possible and create an environmental seal. They achieve this through the epoxy lining. As the heat shrink is activated, the epoxy melts and is pushed out. As it cools it creates a barrier that protects your connections from exposure.
What industries use Pacer ring terminals?
