Sausage Stuffing Horn / Tube

A tapered nozzle that funnels ground meat into casings when making fresh sausage.

A sausage stuffing horn is a cone-shaped tube that attaches to a grinder or stuffer, over which an empty casing is gathered like a sleeve. As ground, seasoned meat is forced through the horn it fills the casing steadily, with the casing fed off the tip as it plumps. Horns come in several diameters to match casing sizes from breakfast links to large salami.

A sausage stuffing horn is the simplest piece of equipment in the sausage maker's kit, and one of the most consequential. It is a passive fitting—a short, hollow tube with no moving parts—that mounts onto the outlet of a meat grinder or sausage stuffer and narrows the flow of seasoned meat to a diameter small enough to enter a casing. Its job is purely dimensional: reduce the outlet, give the casing something smooth to slide along, and present the casing at a controlled speed. Get it right and the horn disappears into the process. Get it wrong—wrong diameter, warm, or rushed—and every link in the batch pays the price.

The outside diameter of the horn sets the diameter of the finished sausage, since the casing wraps tightly around the meat as it leaves the tip with only small variation from how firmly the mix is packed. A casing should slide on with slight resistance and feed off the tip under the operator's control. Too narrow and the casing tears as it climbs on. Too wide and it wrinkles, traps air, and bursts when the meat expands during cooking. Most home sausage makers end up owning two or three horns—a 13 mm for sheep and breakfast links, a 19–22 mm for bratwurst and standard hog casings, and sometimes a 30+ mm horn for large pork or beef rounds.

The horn also controls, indirectly, how gently the meat is handled. A dedicated sausage stuffer pushes meat with a piston at low pressure, keeping fat particles intact and the mix cold. A grinder's stuffing attachment uses the same auger that just ground the meat, smearing fat and warming the mix. The horn works with both, but link quality is dramatically better with a real stuffer—and that is one variable the horn cannot fix on its own.

Types & varieties

Plastic (food-grade nylon or polypropylene)

The most common home-use horn; lightweight, inexpensive, and often translucent so you can see air pockets moving through the bore.

Stainless steel

Preferred for heavy and commercial use; resists warping, handles high pressures, and is the most sanitary option.

Straight (cylindrical) tube

Uniform diameter end-to-end; produces the most even sausage diameter and is the standard for fresh links.

Tapered or conical horn

Narrows toward the tip; helps the casing climb on and lets one horn serve several casing sizes by feeding from different points along its length.

Multi-piece set

Bundled with a stuffer or grinder to cover snack-stick through bratwurst sizes; typically three or four interchangeable tubes.

Funnel-style horn

Short and wide-flared; used for filling large hog or beef casings, or for transferring mix without a stuffer.

Sizing the horn to the casing

A horn is sized by its outside diameter, because that is the dimension the casing sees. A 19 mm horn makes a 19 mm sausage, give or take a millimeter for casing stretch and how firmly the mix is packed. The general rule is that a casing should slide on with a little resistance—snug enough not to balloon off as it fills, loose enough to feed off the tip without tearing. The pairings below cover the great majority of fresh and cured sausage work at home:

Sheep casings (16–22 mm when relaxed): 13–15 mm horn
Hog casings (28–42 mm when relaxed): 19–25 mm horn
Beef rounds (35–55 mm when relaxed): 25–38 mm horn
Collagen snack-stick casings: 10–13 mm horn
Fibrous salami casings: match the labeled diameter, usually 19, 22, or 25 mm

Common uses

Filling natural hog casings for bratwurst, kielbasa, Italian sausage, and boudin blancFilling natural sheep casings for breakfast links, merguez, and chipolataFilling collagen or fibrous casings for snack sticks, summer sausage, and salamiLinking fresh sausages by twisting filled casings to uniform lengthsStuffing burger-style patties or large meat logs when a wide horn is fittedExtruding cookie dough, mashed-potato shapes, or churros from a stuffer (off-label use)

Tips & pitfalls

Match horn diameter to casing diameter: the casing should slide on with slight resistance, not balloon off the tip and not catch or tear on the way up.
Keep the meat, horn, and stuffer barrel cold (around 32–38 °F / 0–3 °C); warm fat smears into a paste and the casing begins to slip off the horn mid-fill.
Slide the casing all the way onto the horn and tie a knot or clip the end before you begin pumping—any air left inside the horn gets trapped as bubbles in the first few links.
Hold the filled casing at the tip with your fingers and let it slide off as it fills; a slow, even pace prevents blowouts far better than a fast push.
Prick trapped air pockets with a clean sausage pricker or sterile needle before cooking or hanging; bubbles expand in the heat and split the casing from the inside.
Do not pack the stuffer so tight that fat squeezes out ahead of the protein matrix—aim for firm but not compressed, and the links will have a clean, springy bite.
Avoid using a grinder's stuffing attachment for long runs if you have a dedicated stuffer available; the grinder shears rather than pushes, which smears fat and overheats the mix.
If a casing sticks or will not feed on, slip it off and soak it longer in warm water; dry or under-soaked casings are the single most common cause of torn links.

Good to know

Also called: Stuffing tube, sausage horn, stuffing nozzle, stuffer funnel
Function: Passive fitting that narrows the outlet of a grinder or stuffer to casing diameter and presents a smooth surface for the casing to slide along
Common materials: Food-grade white nylon or polypropylene plastic; stainless steel; aluminum occasionally seen but less preferred for acidic mixes
Typical diameters: Roughly 10 mm (snack sticks) up to 38 mm (large hog and beef casings); 13, 19, 22, 25, and 32 mm are widely stocked
Pairs with: Vertical and horizontal sausage stuffers (manual or electric) and the stuffing outlet of most meat grinders
Casings it fits: Natural hog, sheep, and beef casings; collagen casings; fibrous casings; cellulose peelable casings
Cleaning: Plastic horns are usually dishwasher safe; stainless steel is easiest to sanitize and lasts longest
Approximate price range: Plastic horns $5–15 individually, sets $15–40; stainless-steel horns $15–60 each
