Yes – Haisstronica offers crimpers specifically for wire ferrule sleeves (insulated end ferrules). Their ferrule crimping tool is a ratcheting electrical crimp tool that handles a range approximately from AWG 24 to AWG 8, covering most ferrule sizes. This tool produces a firm, square crimp on ferrule connectors without crushing or damaging the insulation. The ratcheting mechanism applies even pressure around the ferrule, resulting in a reliable termination of stranded wire. In short, you can confidently use Haisstronica’s electrical crimping tools to crimp insulated ferrule sleeves for neat and secure wiring ends.

Yes, Haisstronica makes a specialized crimper for spark plug ignition wires. It’s a ratcheting tool with a 3-hole die designed to strip and crimp the terminals on 8 mm–8.5 mm spark plug cables. This ignition wire crimper lets you crimp the plug terminals (both the conductor and the insulation crimps) securely onto the high-voltage wire. The tool usually features built-in stripping holes to remove just the right amount of insulation and a ratchet that ensures you get a firm crimp on the spark plug terminal. Using Haisstronica’s dedicated spark plug terminal crimper is highly recommended for this job – it provides the precise cavity size and leverage needed to crimp thick ignition wires properly. (Note that typical general-purpose electrical crimpers are not suitable for spark plug leads due to the larger diameter and different style of those terminals.)

Haisstronica gives you both options. They offer fixed-die crimpers that are dedicated to specific connector types (for example, one for insulated terminals, another for ferrule sleeves, another for open-barrel pins), and they offer a quick-change jaw crimping tool that can handle multiple connector types by swapping dies. If you prefer simplicity and do the same type of crimps often, you might use separate fixed-die tools optimized for each connector. However, if you want one versatile tool, Haisstronica’s 9-inch ratcheting crimper with interchangeable jaws is ideal – you can swap crimping dies in seconds to switch between connector types. This quick-change system means a single crimper frame can crimp a full range of connectors just by using the appropriate die set. In summary, you don’t need to buy entirely separate tools for every connector if you go with the quick-change system: one quality Haisstronica crimper can cover many needs by using different jaws.

Haisstronica produces tools for almost every kind of electrical crimp connector. You can crimp a wide variety of connectors with their tools, including:

• Insulated terminals: e.g. vinyl/nylon ring terminals, spade lugs, fork terminals, and butt splice connectors (including heat-shrink butt connectors). Haisstronica’s insulated terminal crimpers are color-coded for red/blue/yellow terminals (AWG 22–10).
• Non-insulated terminals: open-barrel terminals and receptacles (common in automotive or electronics connectors like Dupont/JST). They have a specialized open-barrel terminal crimper for these.
• Wire ferrules (end sleeves): insulated ferrule collars for finely stranded wires. Haisstronica’s ferrule crimpers form a solid square crimp on ferrules from small electronics sizes up to larger control wiring sizes.
• Specialty connectors: For example, MC4 solar panel connectors (using the solar crimping tool kit), and spark plug ignition terminals (using the spark plug wire crimper as mentioned above). These tools are purpose-built for those connectors.
• Large cable lugs: Haisstronica also offers heavy-duty crimpers (including hydraulic crimpers) for large gauge battery lugs and cable terminals. These allow you to crimp battery cables and welding cables (e.g. AWG 8 down to 1/0 or larger) with hex or indent style crimps.

In essence, Haisstronica’s crimping tools for wire connectors cover everything from tiny crimp-on butt connectors and ferrules to substantial power lugs. Their product line is remarkably versatile, accommodating various wire types and terminal styles. Whether you're working with standard electrical crimp connectors, automotive plug pins, or marine terminals, there’s likely a Haisstronica tool or die set that fits the job. (The only exception would be very specialized crimping tasks like steel wire rope crimp sleeves, which require a different type of tool not in this range.)

Absolutely. Haisstronica sells additional crimping dies (jaw inserts) separately, so you can expand your crimper’s capabilities or replace worn-out jaws. If you have the Haisstronica quick-change ratcheting crimper frame, you can purchase different die sets for various connector types – for example, dies for insulated terminals (22–10 AWG), dies for solar MC4 connectors (often 14–10 AWG), dies for ferrules, non-insulated terminals, etc. Each die set usually comes with the two halves of the jaw and the retaining screws (if needed) to secure them in the crimper. Swapping them is simple (on the quick-change model it’s tool-free; on other models you might remove a couple of screws). This means you can equip one Haisstronica crimping tool to crimp many types of connectors just by using the appropriate interchangeable dies. Replacement dies are also useful if you wear out a specific crimping head over time – you can just replace the die instead of buying a whole new tool. You can find Haisstronica’s crimping dies on their website or through their authorized retailers, usually listed by the wire gauge range or connector type they support (for instance, “Crimping Die for Solar Connectors AWG 14–10” or a set labeled A, B, C, etc., corresponding to different applications). In short, yes – you can buy additional jaws to customize or maintain your Haisstronica crimper, making it a flexible long-term solution.
