JS8615-2 1:1 Welding Steel-Type Dual-Component Tile Grout Adhesive Gun (With linkage labor-saving device)
A welded steel 1:1 dual-component grout gun with a linkage labour-saving device: 200 KG push force, 230 KG tolerance, and a 45:1 drive ratio, at 800 g.

Product Overview
A welded steel 1:1 dual-component grout gun with a linkage labour-saving device: 200 KG push force, 230 KG tolerance, and a 45:1 drive ratio, at 800 g. The high ratio plus the linkage is what keeps a full pack of epoxy workable through a static mixer by hand.
Why Buyers Choose This Model
45:1 With A Labour-Saving Linkage
A very high drive ratio combined with a linkage labour-saving device, which together are what make a 45:1 gun usable through a full pack rather than only the easy first third.
Welded Steel At 800 g
Welded steel construction at 800 g, lighter than the plastic-bodied JS8612-A while carrying a 230 KG tolerance.
1:1 Ratio Held Mechanically
Both rods driven from the one linkage, so the proportion does not drift as the cartridge empties.
12 Pieces Per Carton
Packed 12 per carton at 62 x 47 x 35 cm, which is worth knowing when planning a mixed container of grout guns.
Where It Is Used
- 1:1 epoxy grout on large tiled areas
- Continuous professional grouting
- Work where trigger effort is the limiting factor
- Distributor ranges needing a welded steel 1:1
The Buyers This Model Suits
Professional Tiling Crews
Grouts continuously and needs the labour-saving linkage rather than raw force.
Contractors On Stiff Epoxy
Works with products where a 30:1 gun becomes hard going after the first third of the pack.
Distributors Needing Steel At Mid Price
Sits below the 420 KG JS8615-3 while keeping the welded steel construction.
What It Fixes
Trigger Effort Through A Full Pack
45:1 plus the linkage device is the specific answer to the pull getting heavier as the pack empties.
Steel Guns Being Heavy
800 g of welded steel is lighter than most plastic grout guns of similar capability.
Ratio Drift Late In The Cartridge
The one-linkage drive holds the proportion to the end.

How This Model Is Made
Parts for the JS8615-2 are produced in our own workshops in Jinli Town, Zhaoqing. This model is predominantly a metal product, made on our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.

Getting The Best Out Of It
Step 1
Confirm the cartridge is 1:1 before loading.
Step 2
Fit the static mixing nozzle and discard the first short length of mixed product.
Step 3
Let the 45:1 ratio and the linkage do the work rather than gripping harder.
Step 4
Clean the plunger seat and nozzle mount before the epoxy cures.
