Watch a commercial waterproofing crew or a window installer working through hundreds of feet of joint in a day, and you’ll notice their guns look wrong — fatter barrels, no plastic cartridge sticking out, and a foil twist dangling from the nozzle when they reload. That’s a sausage caulk gun, and the foil chubs it fires are how the professional side of the sealant industry has packaged product for decades. Most homeowners have never seen one, which is a shame, because for anyone who moves real quantities of sealant — and even for some serious DIYers — sausage systems are cheaper per ounce, produce far less waste, and lay a noticeably more consistent bead. Here’s how the system works, what it costs, and an honest take on who should actually own one.
What a Sausage Pack Is
Instead of a rigid plastic cartridge with a built-in nozzle, a sausage (also called a chub) is sealant packed in a collapsible aluminum-foil film casing, clipped at both ends — genuinely shaped like a bratwurst. The standard US size is 20 ounces, exactly double the common 10-ounce cartridge, with 10-ounce sausages available in some product lines. The sausage has no nozzle of its own: the gun provides a reusable barrel, a cone-shaped nozzle that threads onto the barrel cap, and a plunger with a flexible cup that crushes the casing from behind, wringing sealant forward like toothpaste. When the sausage is empty, you’re left with a crushed foil disc the size of a hockey puck — that’s the entire waste stream.
Loading takes fifteen seconds once you’ve done it twice: retract the plunger, drop the sausage in nozzle-end first, snip the leading clip end off with snips or a utility knife, screw on the cap and nozzle, squeeze until sealant reaches the tip.
Why Pros Standardized on Sausages
Material cost
Commercial-grade sealants sell meaningfully cheaper per ounce in sausage form. A polyurethane like Sikaflex or a silicone like Dow 795 that runs $10 to $12 in a 10-ounce cartridge is typically $14 to $18 in a 20-ounce sausage — double the product for 40 to 60 percent more money. A crew burning twenty sausages a week saves thousands a year on identical chemistry.
Waste and trash
Empty cartridges are bulky rigid plastic with an ounce of sealant always stranded inside the geometry. Empty sausages crush flat; a day’s production fits in a coffee can, and the plunger cup wrings the casing nearly dry — recovery of product is close to total. On LEED-tracked commercial jobs, that waste reduction is actually specified.
Fewer reloads, better beads
Twice the capacity means half the interruptions, and every reload is a chance for a bead to start fat or stuttery. Sausage guns also tend to be higher-thrust-ratio tools than hardware-store cartridge guns, so thick polyurethanes flow smoothly in cold weather instead of demanding a two-handed death grip.
Reusable nozzles you can shape
Because the nozzle belongs to the gun, not the package, pros cut and keep a quiver of nozzles trimmed for different joint sizes, and simply swap them. You can also buy replacement cones in bulk for pennies.
What the Guns Cost
| Type | Examples | Price |
|---|---|---|
| Manual sausage gun | Albion B12S/B26, Newborn 620AL, COX Jumbo | $40–$120 |
| Cordless powered sausage gun | Milwaukee M18 20oz, DeWalt 20V, Makita 18V | $180–$350 bare tool |
| Combo/convertible (cartridge + sausage) | Albion and COX multi-barrel kits | $70–$150 |
Albion is the name to know in manual guns — the B-line barrels last decades on commercial crews and rebuild parts (plunger cups, barrels, nozzles) are all available separately. Newborn and COX make excellent tools for less. On the powered side, the Milwaukee M18 sausage gun has become the de facto standard on waterproofing and glazing crews; constant-speed motorized flow with a thick polyurethane produces beads a human trigger finger simply can’t match over a long joint. Compare all this to $8 for a basic cartridge gun and you see why the system stays professional: the gun is an investment that only pays back in volume.
What Sealants Come in Sausages
This is the catch for homeowners: sausage packaging is a commercial-line thing. You’ll find polyurethanes (Sikaflex 1a and 2c, Vulkem 116, Masterseal NP1), commercial silicones (Dow 790/795/995, GE SilPruf, Pecora), hybrids/STPs, and specialty glazing and roofing sealants — sold at waterproofing suppliers, glazing distributors, White Cap-style contractor yards, and online. What you will NOT generally find in sausages: the consumer kitchen-and-bath silicones, painter’s acrylics, and adhesive caulks that fill the home-center aisle. Those live in cartridges. So a sausage gun doesn’t replace your cartridge gun; it adds a second, higher-volume system for premium sealants. The good news is the commercial sausages are frequently better products than their retail cousins for the same or less money — NP1 in a sausage around $11 to $14 is one of the best exterior sealant values in the country.
Sausage vs Cartridge vs Bulk: The Full Ladder
For completeness, the sealant packaging ladder runs: 10-ounce cartridge (retail standard), 29-ounce quart cartridge (big rigid tube, needs its own large cartridge gun — common for subfloor adhesive and concrete sealants), 20-ounce sausage (commercial standard), and true bulk — 2-gallon and 5-gallon pails loaded into bulk guns with a follower plate, used by high-volume waterproofing operations. Bulk beats sausages on cost at industrial scale but loading is messy and cleanup real; sausages are the sweet spot of cost, cleanliness, and speed, which is exactly why they own the middle of the professional market. Many sausage guns convert to bulk-loading with a barrel swap if you ever scale up.
Living With a Sausage Gun: The Real-World Quirks
- Cut the clip end cleanly and load that end toward the nozzle. Loading backward or leaving foil flaps means casing fragments migrate into the nozzle mid-bead. Everyone does it exactly once.
- Burp the barrel. After loading, run the plunger up slowly until sealant just appears at the tip before starting your joint, or the first foot of bead is air-spattered.
- Partial sausages store better than partial cartridges. Cap the nozzle or swap to a sealed cap and the foil casing, unlike a punctured cartridge, has no air inlet at the back — opened sausages routinely survive weeks in the gun.
- Clean the plunger cup occasionally. A casing rupture (rare, usually from a gouged barrel or frozen sealant) coats the cup; wipe with the sealant’s solvent before it cures or the cup’s seal degrades.
- Cold thickens everything. Winter crews keep sausages in a warm truck cab or cooler with hand warmers; a warm sausage guns like summer.
Choosing Your First Sausage Gun
If you’re stepping in, three specs matter. Thrust ratio first: 12:1 handles most sealants; 18:1 to 26:1 earns its price on thick polyurethanes and cold-weather work — the higher-ratio Albions are the buy-once choice. Barrel material second: aluminum barrels are lighter and standard; steel survives being dropped off scaffolding. Third, check that the model takes both 10- and 20-ounce sausages if you’ll use smaller specialty packs. Skip bargain imports with plastic plunger cups — the cup is the part doing all the work against the foil casing, and a cheap one leaks past and wastes exactly the product you bought the gun to save. Budget $10 for a bag of spare nozzles and a spare cup with the gun and you’re outfitted for a decade.
Should You Buy One?
If your caulking life is a tub surround every few years and some baseboards, no — a quality dripless cartridge gun covers you, and the consumer products you want don’t come in sausages anyway. The math changes fast with volume. Re-sealing every window and siding joint on a whole house, maintaining rental properties, log-home chinking, RV and marine work, or any recurring exterior sealant program: a $60 Albion or Newborn manual gun plus commercial sausages pays for itself inside the first project — roughly $3 to $5 saved per 20 ounces of premium sealant, plus better product access than the retail aisle offers. Serious volume justifies the Milwaukee. Either way you’ll lay straighter, more consistent beads with less trash at your feet, and you’ll understand why, on any big commercial site in America, the cartridge gun is the amateur tell and the sausage gun is just called “the gun.”
