Cartridge Caulking Guns
Skeleton and frame guns for 300 ml cartridge sealant, from a 175 g economy PP frame to a 750 g nine-bearing body

Cartridge, sausage and powered guns for joint sealing and waterproofing trades
Sealing is the last operation on a building and the first one to be blamed when water gets in. The tools that matter are the ones that keep a bead the right size for a full shift and stop dispensing the moment the trigger is released, because wasted sealant and uneven joints are the same problem seen from two sides.
A gun without anti-drip keeps feeding after the trigger is released. Over a day that is measurable product loss plus clean-up. Anti-drip is standard on every professional model we make, and adjustable on the JS8605, JS8608 and JS8611 series.
Cold sealant needs more force, and a frame rated only to its working figure bends. That is why push force and maximum tolerance are published separately: JS-8622-A is 180 KG working and 250 KG tolerance.
Contractors rarely standardise on one product. JS8611 is adjustable from 18:1 to 28:1 so a single gun handles thin acrylic and stiff polyurethane without being wrong for both.
Expansion joints run for metres. The nine-bearing sausage guns cut pull weight, and the pneumatic and battery models remove it.

Viscosity and pack format decide the gun. Send the product datasheet and the pack size rather than asking for a category.
Occasional, trade or professional maps onto bearing count, body construction and tolerance figure. We quote one model per tier so your range has clear steps.
Anti-drip behaviour depends on the sealant as well as the gun. Samples let the crew confirm it before you buy quantity.
One barrel colour and logo treatment across the tiers makes a coherent own-brand range rather than a shelf of unrelated tools.
Push plates, rods and handle sleeves are quoted with the order so your trade customers can be serviced.
Push force, maximum tolerance and drive ratio describe three different things. Confusing them is the most common reason a gun fails in the field.
Sausage packs cut cost per litre and packaging waste; cartridges are simpler and universally stocked. The right answer depends on who your customer is.
Bearing count is the single clearest indicator of duty level on a sausage gun. Three, seven and nine are genuinely different tools.
Releasing the trigger retracts the rod and drops the pressure inside the cartridge, so the sealant stops being pushed. On JS8605, JS8608-A and JS8611 the amount of retraction is adjustable from the rear attachment.
Cartridges are convenient and widely stocked; sausages cost less per litre and produce far less waste packaging. Crews sealing all day usually move to sausage, which is why the sausage range has the higher bearing counts.
JS8611, at 18:1 to 28:1 with 160 KG push force and 200 KG tolerance, for contractors who cannot standardise on a single sealant.
Production lead time is not published on our old site and depends on quantity, colour and whether tooling is involved. Send the model and quantity on WhatsApp and we will confirm a date before you commit.
Push plates, rods and handle sleeves are available across the current range. For a model you bought several years ago, send us a photo and we will confirm what still fits.
Tell us the products your crews use and the problems they keep hitting, and we will name models rather than categories.
