JS8612-A 1:1 Epoxy Grout Caulking Gun (Plastic Model)
A 1:1 epoxy grout gun in a reinforced plastic body at 250 KG push force and a 300 KG tolerance, 30:1, 1000 g.

Product Overview
A 1:1 epoxy grout gun in a reinforced plastic body at 250 KG push force and a 300 KG tolerance, 30:1, 1000 g. Three specially reinforced steel supports stop the rod slipping under load, which is how a plastic-bodied gun reaches 300 KG. The blue and yellow body is deliberately visible on a site.


Why Buyers Choose This Model
250 KG From A Plastic Body
Three specially reinforced steel supports prevent the rod slipping and carry the load, which is what takes a plastic gun to a 300 KG tolerance.
Designed For 1:1 Epoxy Grout
Meticulously designed for efficient application of epoxy grout at a 1:1 ratio, so the proportion is correct from the first squeeze to the last.
Ergonomic Handle
Optimised to reduce strain during operation, which on epoxy through a mixer is what determines how long a crew can keep working.
Visible On Site
The blue and yellow colour scheme is a deliberate choice: a grout gun that is easy to find on a tiled floor is a grout gun that does not get stood on.
Where It Is Used
- 1:1 epoxy tile grout on floors and walls
- Crews needing force without a steel gun's weight
- Shared-tool sites where tools get mislaid
- Distributor ranges needing a mid-price 1:1 gun
The Buyers This Model Suits
Tile And Stone Installers
Grouts with 1:1 epoxy and needs force through a mixing nozzle without a welded steel gun.
Crews Working Long Sessions
The ergonomic handle is specified to reduce labour intensity and speed the work up, which matters on a large floor.
Distributors Filling A Price Gap
Sits between the light JS8612-B and the welded steel JS8615 models.
What It Fixes
Rods Slipping Under Epoxy Load
The three reinforced steel supports exist specifically to stop the rod slipping and to prevent deformation.
Steel Guns Being Too Heavy
1000 g in reinforced plastic against 970 g of iron on the JS8615, with 50 KG more push force.
Tools Lost On A Tiled Floor
The blue and yellow scheme is visibility, not decoration.
How It Is Built
Robust Plastic Construction
The gun boasts a robust plastic construction that strikes a balance between durability and lightweight design, enhancing ease of operation during extended construction tasks.
Specially Reinforced Steel Supports
Equipped with three steel supports specially reinforced to prevent the gun’s rod from slipping, these supports enhance the rod’s durability, prevent deformation, and avoid scratches.
Eye-Catching Color Scheme
The unique blue and yellow color scheme of the gun’s body captures attention and makes it a standout presence on the construction site.
Ergonomic Handle Design
The ergonomic handle design, optimized to reduce strain during operation, ensures a more comfortable and relaxed construction experience, minimizing labor fatigue.
Time and Energy Saving
The user-friendly handle design not only reduces labor intensity but also speeds up the construction process, boosting efficiency and conserving time and energy.

How This Model Is Made
Parts for the JS8612-A are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off 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.
- Aluminium Tube Painting: Up to 10 colours with customisable patterns.
- Aluminium Tube Laser Engraving: Engraved logos, text and patterns on stamped fittings and aluminium tubes.
- Self-Adhesive Logo Labels: Applied to the product in the position the buyer specifies.
- Multi-Colour Logo Printing: Paint screen printing in any colour, with several colours printed at once.
- Tag And Product Screen Printing: Screen printed tags and product markings, multi-colour capable.
Getting The Best Out Of It
Step 1
Check the cartridge is 1:1 before loading; the gun cannot correct a different ratio.
Step 2
Fit the mixing nozzle and discard the first short length of mixed product.
Step 3
Work steadily rather than forcing the trigger, since 30:1 already provides the mechanical advantage.
Step 4
Clean the plunger seat before the epoxy cures, because cured two-component product does not come off.
How It Compares In Our Range

JS8612-A Questions
What are the ratings?
250 KG push force, 300 KG maximum tolerance, 30:1 drive ratio, 1000 g net weight. Stock colour is blue.
Can a plastic body really take 300 KG?
The load is carried by three specially reinforced steel supports rather than by the plastic itself. Those supports also prevent the rod slipping, which is the usual failure on a plastic grout gun.
How does it compare with the JS8612-B?
JS8612-B is the lighter and cheaper 1:1 option at 100 KG push force, 180 KG tolerance and 50:1, at 650 g. This model has 2.5 times the push force.
How is it packed?
Two pieces per inner box, 20 pieces per master carton at 59 x 41 x 41.5 cm.
What is the minimum order quantity?
2,000 pieces for a customised version, per colour.

Guides That Cover This Model
Choosing A Two-Component Gun By Mix Ratio
The ratio is built into the gun's linkage, so a 1:1 gun cannot dispense a 1:4 product. Match the gun to the cartridge, every time.
