6 Best Weston Stuffer Funnels For Beginners That Prevent Common Issues

You’ve spent hours grinding and seasoning the perfect sausage mix, your casings are soaked, and the stuffer is loaded. Then it happens: the casing splits, air pockets form, or the meat just won’t flow. These common frustrations often boil down to one small, overlooked piece of equipment—the stuffer funnel. Choosing the right funnel isn’t just about convenience; it’s about protecting your time, effort, and ingredients.

Why the Right Stuffer Funnel Prevents Headaches

The stuffer funnel, or stuffing tube, is the critical link between your sausage stuffer and your casing. Its job is to guide the meat mixture into the casing smoothly and evenly. When the funnel is too large for the casing, you risk tearing it before you even start. If it’s too small, you create excessive backpressure, leading to "blowouts" where the meat bursts through the side of the casing.

The two biggest culprits for beginner issues are size mismatches and material. A plastic funnel might create more friction than a stainless steel one, causing delicate sheep casings to snag and rip. Conversely, a steel funnel that’s just a millimeter too wide for your collagen snack stick casings will make loading them impossible without splitting them.

Ultimately, the right funnel makes the entire process faster and more enjoyable. It allows you to produce uniformly filled links without air pockets, which are the enemy of good texture and proper curing. A smooth stuffing process means your meat mix stays cold, your casings stay intact, and you end up with a product you’re proud of.

Weston 3pc. Stainless Steel Set for Versatility

If you plan on making more than one type of sausage, this set is your starting point. It’s the multi-tool of the sausage-making world. You get the flexibility to experiment without having to buy a new funnel for every recipe.

This set typically includes a small, medium, and large funnel, often around 10mm, 20mm, and 30mm. The 10mm is perfect for slim snack sticks, the 20mm handles breakfast links and small Italian sausage, and the 30mm is your go-to for standard bratwurst and kielbasa. This range covers about 80% of the sausages a hobbyist will ever make.

The real advantage here is the stainless steel construction. It’s far superior to the plastic funnels that often come with starter kits. Steel is easier to sanitize, won’t hold onto flavors from your last batch of spicy chorizo, and provides a slicker surface for casings to slide onto. It’s a "buy it once, use it for life" investment that pays for itself in reduced frustration.

Weston 13mm Funnel for Perfect Snack Sticks

Making snack sticks, pepperoni, or any other small-diameter sausage presents a unique challenge. You’re working with delicate, narrow casings that are incredibly easy to tear. Using a standard-sized funnel is a recipe for disaster; you’ll spend more time re-loading ripped casings than you will stuffing.

This is where a specialized funnel like the Weston 13mm shines. Its slim profile is designed specifically for collagen or natural sheep casings in the 18-21mm range. The narrow tube allows the casing to slide on without being stretched to its breaking point, and it ensures a consistent fill without excessive pressure.

Is it a one-trick pony? Yes, but it’s a trick it does perfectly. If you are serious about making snack sticks, this funnel is not a luxury—it’s a necessity. It turns a potentially infuriating task into a smooth, efficient process, giving you the professional-looking results you’re after.

Weston 30mm Funnel for Fast Bratwurst Stuffing

When you move up to larger sausages like bratwurst, Italian sausage, or kielbasa, your main enemy is time. The longer your meat mix sits out, the warmer it gets, which can lead to fat smearing and a poor final texture. A wider funnel is your best defense against this.

The Weston 30mm funnel allows for a high volume of meat to flow quickly and easily into larger hog casings. Trying to stuff a 25-pound batch of brats through a narrow 20mm funnel is a slow, tedious process that puts unnecessary strain on your stuffer and your patience. The 30mm tube drastically cuts down your stuffing time.

This funnel is all about efficiency at scale. For a small 5-pound batch, it’s a nice convenience. For anyone processing a significant amount of meat from a deer or a hog, it’s an essential tool for maintaining quality. You get a firm, even fill without the risk of overworking the meat or letting it warm up.

Weston 4pc. Plastic Funnel Set: A Starter Kit

Let’s be practical: not everyone wants to dive into the deep end with stainless steel. If you’re just testing the waters of sausage making, the Weston plastic funnel set is an intelligent and low-cost entry point. It gives you a range of sizes to experiment with before you know what you’ll make most often.

This kit typically includes four sizes, covering everything from small snack sticks to larger summer sausage. The primary benefit is affordability. You can learn the ropes, figure out which sizes you prefer, and understand the stuffing process without a significant financial commitment.

However, you have to accept the tradeoffs. Plastic is more prone to friction, which can make loading natural casings a bit trickier. It can also stain and retain odors over time, and it simply isn’t as durable as steel. Think of this set as your training wheels; it’s the perfect way to start, learn, and decide where you want to invest in better equipment down the road.

Weston #8 Grinder Kit for All-in-One Grinding

Sometimes the problem isn’t the funnel itself, but how it connects to your equipment. Many beginners start by stuffing directly from their meat grinder, and finding funnels that fit a specific grinder model can be a headache. This kit solves that problem by design.

The Weston #8 Grinder Kit is a matched set, usually including a grinder knife, two grinding plates, and a set of stuffing funnels. The key here is guaranteed compatibility. You know the funnels will attach securely to your #8 grinder head, eliminating any wiggling or leaking that can happen with mismatched parts.

This is the ideal solution for the person who uses their grinder for both grinding and stuffing. It streamlines the process by ensuring all your components work together seamlessly. It’s not a universal funnel set, but for the specific task of stuffing with a #8 grinder, it’s the most straightforward and frustration-free option available.

Weston 40mm Stainless Funnel for Durability

When you’re making large, heavy sausages like summer sausage, bologna, or salami, you need equipment that can handle the pressure. These sausages require a very tight fill to prevent air pockets and ensure proper curing. A flimsy plastic funnel can flex or even crack under that kind of force.

The Weston 40mm Stainless Funnel is built for this heavy-duty work. Its wide diameter is made for large fibrous or collagen casings, and the robust steel construction won’t budge, even when you’re cranking down on a 15-pound stuffer full of dense, cold meat. This ensures you get that crucial, tight pack every time.

This is a specialized tool for a specific purpose. You won’t use it for brats or snack sticks, but for the craft of charcuterie and large-format cured sausages, it is indispensable. It represents a commitment to a particular style of sausage making and provides the durability needed to do it right for years to come.

Matching Weston Funnel Size to Your Sausage Casing

All this talk about funnels comes down to one simple rule: the funnel must match the casing. The funnel’s outer diameter should be significantly smaller than the final stuffed diameter of your sausage. This gives you room to load plenty of casing onto the funnel and allows it to fill out properly without tearing.

Here is a simple guide to get you started. Think of it as a baseline, and don’t be afraid to adjust based on your specific casings.

• Snack Sticks & Pepperoni (18-22mm casings): Use a 10mm to 13mm funnel.
• Breakfast Links & Frankfurters (22-26mm casings): Use a 15mm to 20mm funnel.
• Bratwurst & Italian Sausage (30-38mm casings): Use a 20mm to 30mm funnel.
• Summer Sausage & Salami (40mm+ casings): Use a 30mm to 40mm funnel.

The most common beginner mistake is trying to use a funnel that’s too close in size to the casing. For example, using a 30mm funnel for a 32mm casing leaves no room for error and invites tearing. Always choose a funnel that gives the casing plenty of space to bunch up and expand as it fills. This single principle will solve the majority of your stuffing problems.

Choosing the right stuffer funnel is a small detail that makes a world of difference. It transforms sausage making from a frustrating chore into a rewarding craft. By matching your funnel to your casing and investing in the right materials for the job, you set yourself up for success and a freezer full of delicious, homemade sausage.
